Unprocessable entity
Last updated: June 17, 2026
The requested action could not be performed, is semantically incorrect, or failed business validation. The following issues may return from an UNPROCESSABLE_ENTITY error.
Returns from the Billing Agreements API.
| Cause | Previously canceled: The payer performed an API call to modify,
execute, or otherwise interact with a previously canceled billing
agreement. Oversight: The payer misunderstood the current agreement status. Business logic error: The system that is integrated with the API
improperly checked the agreement status before attempting operations.
|
|---|
| Impact | Operations failure: The payer potentially cannot perform operations,
such as processing payments, on the canceled agreement. Service disruption: Unintended or improperly communicated canceled
billing agreements can disrupt service or billing processes. Payer dissatisfaction: Repeated transaction failures can lead to
frustration and confusion among payers.
|
|---|
| Resolution | Verify agreement status: Confirm the canceled status of the billing
agreement. Review business logic: Ensure that the integrated system properly
checks the status before attempting operations. Communicate with payers: Inform the payer about the unintended
canceled billing agreement to resolve issues. - Create a new billing agreement.
|
|---|
Returns from the Billing Agreements API.
| Cause | Incorrect billing agreement ID: The ID in the API request is
incorrect. Improper billing agreement: The API request uses a missing billing
agreement. Permission issue: The requesting account lacks permissions to manage
the billing agreement.
|
|---|
| Impact | Disrupted workflows: Workflows that use the billing agreement ID can be
disrupted, which can lead to failures in other business operations. |
|---|
| Resolution | Verify billing agreement ID: Ensure the accuracy of the billing
agreement ID in the API request. Check agreement status: Confirm that the billing agreement ID belongs
to an active billing agreement. Elevate permission: Ensure that the requesting account holds
appropriate permissions to manage the billing agreement.
|
|---|
Returns from the PayPal Orders v2 or Payments v1 APIs.
| Cause | - You tried to pay with an expired card.
- An expired card cannot be used for payments.
- The payer must use a different card or payment method.
|
|---|
| Impact | PayPal stops the payment. The payer cannot finish the purchase. This can
cause lost sales. |
|---|
| Resolution | - Show an error message that the card is expired.
- Ask the payer to use a different card or payment method.
- Help the payer switch payment methods and finish the payment.
|
|---|
Returns from the Billing Agreements API.
| Cause | Duplicate reference: The transaction or billing agreement attempts to
reference the sender and receiver of payment as the same entity, which is
invalid. |
|---|
| Impact | Disrupted workflows: Intended payments or subscription setup fail,
leading to unprocessable billing agreements and transactions. Disrupted revenue: Failed processes can lead to disruption of
automated systems that use billing agreements and ongoing
subscriptions.
|
|---|
| Resolution | Confirm separation: Ensure that the sender and receiver are different
entities. Review API request: Ensure you use distinct PayPal account IDs or
email addresses for the sender and receiver. Implement validation checks: Ensure that your application checks to
prevent users from setting up billing agreements with duplicate
entities. Verify account details: Ensure that your application uses the correct
account details for transactions and billing agreements. Implement retry mechanism: Develop business logic that waits a short
period before attempting the request again, gradually increasing the
wait time with each attempt.
|
|---|
Returns from the Billing Agreements API.
| Cause | Unsupported code: PayPal does not support the currency code in the API
request. Region limitations: The region from which the API was initiated may
not support the currency code. Account restrictions: The merchant account may have restrictions or
limitations on supported currencies.
|
|---|
| Impact | Process failure: The billing agreement fails due to the use of
unsupported currencies. Revenue loss: Subscriptions or recurring payments do not proceed due
to this error, causing delays or issues for the payer.
|
|---|
| Resolution | Verify currency support: Confirm that PayPal supports the currency
code. Verify currency settings: Confirm that your PayPal business account
can use the necessary currencies . Cross-check regional restrictions: Ensure that your region does not
restrict the currency used in your transaction or billing agreement. Change currency codes: Change the currency code used in your API
request to a supported currency for your location or account.
|
|---|
Returns from the Billing Agreements, Payments v1, and Orders v2 APIs.
| Cause |
- Duplicate invoice ID: The API request uses a duplicate invoice ID. All
transactions and billing agreements require a unique
invoice_id. - Reused invoice ID: The transaction or
billing agreement uses a processed invoice ID typically due to a logic
error or failure to manually update the ID.
|
|---|
| Impact |
- Rejected requests: The system prevents the completion of billing
operations, potentially affecting liquidity and payer satisfaction.
|
|---|
| Resolution | Contact customer support : If your workflow requires duplicate invoice IDs, contact customer
support. Confirm invoice usage: Confirm the use of unique invoice IDs in your
billing agreements and transactions. Implement invoice ID mechanisms: Develop logic that generates a unique
invoice ID for each transaction and billing agreement. Incorporate logs: Track and verify invoice IDs in the application to
prevent reuse and assist with future debugging.
|
|---|
Returns from the Billing Agreements API.
| Cause | Billing address issues: PayPal could not confirm the billing address
for the payment method. Expired card: The payer used an expired or canceled payment
instrument, such as a credit card. Declined transaction: The bank or card issuer declined the transaction
due to reasons such as suspected fraud or account restrictions. Potential risk: The payer account may have insufficient funds, may
pose a risk, or may have encountered a compliance issue. Incorrect billing information: The user entered incorrect information,
such as CVV, expiration date, or account number.
|
|---|
| Impact | Payment failure: The payer cannot complete the payment, potentially
affecting their access to services or products. Payer dissatisfaction: Repeated transaction failures can lead to
frustration among payers. Revenue loss: The merchant may experience a loss of revenue due to
unsuccessful transactions.
|
|---|
| Resolution | Verify payment method: Ensure that the payer uses a valid, active, and
sufficiently funded payment method. Fund availability: Confirm with the payer that their account holds
sufficient funds or is within their credit limit. Contact financial institution: Encourage payers to contact their bank
or card issuer to resolve any temporary holds or restrictions. Update billing instrument: If the payer used an expired or invalid
instrument, ask the payer to update their payment information.
|
|---|
Returns from the Billing Agreements API.
| Cause | |
|---|
| Impact | Disrupted workflows: The merchant cannot process future payments from
the payer without manually acquiring authorization again. Disrupted revenue: Additional authorization requests can impact
post-purchase revenue streams.
|
|---|
| Resolution | Contact customer support: Send a request to customer support to enable
reference transactions for your account. Enabling reference
transactions may require you to provide additional information about
your account. For more information, see Initiate future transactions . Verify configurations: Ensure that you configured your account
settings to support reference transactions. PayPal may request
additional information regarding your account to enable this feature.
For more information, see Initiate future transactions .
|
|---|
Returns from the Billing Agreements API.
| Cause | No approval: The merchant did not request or was not approved for
channel-initiated billing. Improper configuration: The merchant account settings do not include
necessary features, configurations, or permissions. Account restrictions or limitations: The merchant account may have
restrictions or limitations based on their account type or region.
|
|---|
| Impact | Process failure: The merchant cannot create or manage their billing
agreement. Revenue loss: Subscriptions, recurring payments, or other
functionality reliant on channel-initiated billing do not proceed due
to this error.
|
|---|
| Resolution | Contact customer support: Work with customer support or your account
manager to inquire about enabling channel-initiated billing support. Review account settings: Ensure that your account settings support the
desired billing features.
|
|---|
Returns from the Payments v2 or Orders v2 APIs.
| Cause | The PayPal order_id has already been authorized through
an API request. If the order was created with intent="AUTHORIZE", only
one authorization is allowed per order. A second authorization will be
declined with this error code. The merchant may have made a duplicate request or call that failed
because the original call succeeded and has already blocked funds on
the customer's PayPal account. The merchant may have missed reading the successful API response from
the original authorization call due to network issues or system
latencies.
|
|---|
| Impact | There is no impact on the original authorization. This is a decline on
a second attempt at authorizing the same PayPal order. A merchant cannot authorize a partial amount of an order and authorize
the remainder separately. In that situation, the merchant must create
a new PayPal order or realize a loss in sales.
|
|---|
| Resolution | Authorize the full order amount in a single request, then create
multiple captures instead of multiple authorizations. Create multiple captures by setting final_capture="false" in the capture API requests. This allows for cases such as a split
shipment when captures occur at different times based on inventory
availability. If the API call was made because the merchant's systems weren't
updated with the latest order status in PayPal, the merchant may want
to integrate PayPal webhooks.
Webhooks are instant HTTP POST requests from PayPal to the merchant
servers, allowing them to automatically receive and update the latest
PayPal order status. If the API calls take too long and cause PayPal responses to time out
on the merchant end, contact PayPal technical support.
|
|---|
Returns from the Orders v2 API.
| Cause | The PayPal order is already in the "captured" state: The payment is
complete, and funds have settled into the merchant's PayPal account.
No new captures can be created on the given order. Single capture per order: If you're creating PayPal orders with
intent="SALE", only one capture is allowed per PayPal
order. Duplicate request due to missing API response record: The merchant did
not record an API success response on the initial capture call and
made the same request again. Upon seeing the initial request go
through, PayPal rejects the request as a duplicate.
|
|---|
| Impact | If the merchant has captured only a partial amount of the total order,
they will not be able to capture the remaining amount unless they
create a new PayPal order. No buyer impact if the original intent was to have a single (partial
or full) capture on the order. However, there's likely a sync issue
between merchant records and the latest PayPal order statuses,
resulting in a redundant capture API call.
|
|---|
| Resolution | If you want to create multiple captures, use
intent="AUTHORIZE", not intent="SALE". With
intent="AUTHORIZE", an
authorization is
created first on the PayPal order. Then, one or more captures can be
created on the authorization. Ensure that the final_capture parameter in the capture authorized payment API call is set as false to accommodate further capture API calls.
You'll also need to provide a unique invoice_id for each
capture. If you want to create a single-shot capture, that's already happened.
Ensure the API response (success or decline) is recorded in the
database to avoid duplicate API calls. You may want to subscribe to PayPal webhooks that are HTTP POST requests to inform merchant servers about payment status changes.
|
|---|
Returns from the Payments v1 or Orders v2 APIs.
| Cause | Incomplete checkout process: The buyer may have initiated the checkout
process but did not complete the approval step required by PayPal. Missing payment source: The request may not include a valid
payment_source, which is required for the order approval.
|
|---|
| Impact | The payment is declined, and the payment is not processed. This can lead
to delays in completing the purchase. |
|---|
| Resolution | Redirect to approval URL: Ensure that the buyer is redirected to the '
rel':'approve' URL returned as part of the HATEOAS links
within the Create Order call. This URL directs the buyer to the PayPal
checkout flow to approve the order. Include valid payment source: Ensure that the request includes a valid
payment_source.
|
|---|
Returns from the Orders v2 API.
| Cause | The API returns this error when the payee's account is not set up to
receive card payments. The payment is not processed and will not go
through until card payments are enabled on the payee's account. This error may also show up if the payee has not been fully onboarded
to accept payments with PayPal Complete Payments.
|
|---|
| Impact | The payment process is halted, preventing the buyer from finalizing
their purchase. This can lead to lost sales if the issue is not
resolved promptly. The error affects all customers who attempt to send payments to this
specific payee, not just a single customer.
|
|---|
| Resolution | Make sure the payee has completed onboarding correctly. If you are
using the PayPal Complete Payments platform, ask the payee to go
through the onboarding process again and confirm that card payments
are included. If the issue persists, contact PayPal support. If the payee manages their own onboarding, ask them to contact PayPal
directly to enable card payments on their account.
|
|---|
Returns from the Billing Agreements API.
| Cause | Account lock: Violation of PayPal's Acceptable Use Policy due to suspicious activities can lead to an account lock or security
concerns. Account closure: The payer or PayPal closed the account due to policy
violations or other administrative reasons.
|
|---|
| Impact | Billing agreement failure: This error prevents payers from creating or
processing billing agreements and their associated transactions. Service operations: Merchants and payers can experience service loss,
which can cause revenue loss.
|
|---|
| Resolution | Contact customer support : Work with customer support to resolve the issue. Settle account: Resolve debts or disputes that led to the account lock
or closure, then retry the billing agreement.
|
|---|
Returns from the Billing Agreements API.
| Cause | Insufficient funds: The payer does not have enough available funds or
credit. Account limitations: The payer's account may have limitations or
restrictions. Unverified account: The payer uses an unverified account or did not
perform required updates, which prevents payments. Payment method issue: The payer used an expired or canceled payment
instrument, such as a credit card. Account restrictions: The payer account encounters a compliance issue
or external issue that restricts payment processing.
|
|---|
| Impact | Payment failure: The payer cannot complete the payment, potentially
affecting their access to services or products. Payer dissatisfaction: Repeated transaction failures can lead to
frustration among payers. Revenue loss: The merchant may experience a loss of revenue due to
unsuccessful transactions.
|
|---|
| Resolution | Check account status: Verify that both the payer's and merchant's
PayPal accounts are in good standing without any limitations or
restrictions. Verify payment method: Ensure that the payer uses a valid, active, and
sufficiently funded payment method. Configure alternative payment options: Suggest that the payer use a
different payment method. Update account info: Ensure that the payer includes up-to-date account
information, such as billing address and linked payment methods.
|
|---|
Returns from the Billing Agreements API.
| Cause | Request conflict: Multiple requests conflict for the same resource, such
as a billing agreement. PayPal requires the initial request to complete
before processing another request. |
|---|
| Impact | Operation hold: Multiple requests cause a halt on new operations on
the affected resource until the resource processes the original
request. Processing delay: Multiple requests can delay planned modifications or
renewals of a resource.
|
|---|
| Resolution | Verify request status: Check the status of the previous request to
ensure its completion before initiating a new request. Queue requests: Process requests sequentially in a queue, allowing
each request to complete before initiating the next request. Implement error handling: Develop business logic to handle this error
and respond appropriately, such as notifying users of the delay or
logging the error for further analysis.
|
|---|
Returns from the Billing Agreements, Payments v1, and Orders v2 APIs.
| Cause | The API returns this error when a PayPal payment fails due to an issue
with the payment method the buyer selected in their PayPal wallet. |
|---|
| Impact | The payment process is halted, preventing the buyer from finalizing their
purchase. This can lead to lost sales if the issue is not resolved
promptly. |
|---|
| Resolution | Display the error message to the buyer, explaining that the payment
did not go through and that they need to try a different payment
method within their wallet. Redirect the buyer to PayPal checkout so they can choose another
payment source. If the issue persists, ask the buyer to use a different payment
method, such as a credit card. If the issue still persists, suggest that the buyer contact PayPal to
resolve any issues with their PayPal wallet. Use clear instructions to help the buyer complete the payment and
reduce friction during checkout.
|
|---|
Returns from the Orders v2 or Vault v3 APIs.
| Cause | The API returns this error when a transaction is attempted using a saved
payment method token, but the card linked to the token is expired. As a
result, the transaction fails. The buyer must use a different card or
choose another payment method to continue. |
|---|
| Impact | The payment process is halted, preventing the buyer from finalizing their
purchase. This can lead to lost sales if the issue is not resolved
promptly. |
|---|
| Resolution | Enable Real-Time Account Updater (RTAU): If you use PayPal Complete
Payments with advanced credit and debit cards, enable Real-Time
Account Updater on your vault integration. This feature syncs with
card issuers and automatically updates saved cards with new expiration
dates when cards are renewed. Display the error message: Let the buyer know their saved card has
expired. Update the saved payment token: After you receive a new payment token,
update it in your database and remove the old token linked to the
expired card from the PayPal vault and your system. Use clear instructions to help the buyer complete the payment and
reduce the risk of dropped transactions.
|
|---|
Returns from the Payments v1, Orders v2 APIs, and Billing Agreements API.
| Cause | Incorrect formatting: The API request's shipping address fields (such
as street, city, state, postal code, and country) contain formatting
errors or invalid characters. Missing fields: The API request does not contain required shipping
address fields. Validation failure: The address does not match the standards or
validation rules set by PayPal or the postal service of the specified
country. Mismatch: The country code and the country name provided may mismatch,
causing the error.
|
|---|
| Impact | Process failure: The billing agreement, transaction, or subscription
setup will not proceed. Workflow disruption: Delays in processing payments or setting up
recurring billing agreements can impact payer satisfaction and
business operations.
|
|---|
| Resolution | Verify fields: Verify that all required fields in the shipping address
use correct formatting. Match address: Ensure that the address fields, such as street, city,
state, postal code, and country, match the expected format for the
specified country. Verify country code: Ensure that the country code matches the country
name, using address validation tools or services to confirm its
accuracy. Revise address: Contact the payer to correct or confirm the address
details.
|
|---|
Returns from the Payments v1 or Orders v2 APIs.
| Cause | This error occurs when PayPal does not recognize the token ID in the API
request. Possible causes include an invalid or mistyped token. It can also
occur if the API caller does not have the required permissions from the
receiver's account to use the token. |
|---|
| Impact | The payment process is halted, preventing the buyer from finalizing their
purchase. This can lead to lost sales if the issue is not resolved
promptly. |
|---|
| Resolution | Check permissions: If one PayPal account calls an API on behalf of
another, ensure the receiving account has granted the necessary
permissions to the caller. Permissions can be granted using the PayPal
Permissions API or manually through the account settings. Review your code: Ensure the token ID is not altered or modified
before the API call. Reissue token: If the token is invalid or expired, generate a new
token and use it in the API request.
|
|---|
Returns from the Billing Agreements API.
| Cause | Payment method issues: The payment method linked to the billing
agreement might be invalid, expired, or otherwise unable to process
the payment. Insufficient funds: The payer's account may not have enough funds or
credit to cover the transaction amount. Account limitations: The payer's PayPal account might have limitations
or restrictions. Risk factors: If PayPal detects any potential risks based on merchant
history or if there's high risk associated with the transaction,
PayPal will refuse the transaction.
|
|---|
| Impact | Payment failure: The payer's failure to complete the payment can
potentially affect their access to services or products. Payer dissatisfaction: Repeated transaction failures can lead to payer
frustration. Revenue loss: The merchant may experience a loss of revenue due to
unsuccessful transactions.
|
|---|
| Resolution | Verify payment method: Ensure that the payer uses a valid, active, and
sufficiently funded payment method. Check account status: Verify that both the payer's and merchant's
PayPal accounts operate in good standing without any limitations or
restrictions. Correct API request: Double-check the API request parameters to ensure
they are correct and complete.
|
|---|
Returns from the Billing Agreements API.
| Cause | Account restrictions: The payee account restrictions permit only
transactions in certain currencies. Disabled currency: The payee did not enable the specified currency in
their account settings. Region limitations: Certain regions do not make available specific
currencies for the merchant account, resulting in a currency mismatch
during a transaction.
|
|---|
| Impact | Process failure: The merchant cannot create or manage their billing
agreement. Impacted business operations: PayPal does not record failed
transactions, which prevents tracking of fund transfer issues and
could impact subscription services or billing agreements.
|
|---|
| Resolution | - Confirm that PayPal supports the currency code.
Configure account: Ensure that you have enabled the specified currency
in your account settings to accept payment from the payee account. Currency conversion: Consider using a supported currency or handle
currency conversion with PayPal currency conversion services.
