URL Onboarding

Important: PayPal for Marketplaces is available to select partners for approved use cases. For more information, reach out to your PayPal account manager or contact us:


The URL onboarding option requires less setup than Upfront onboarding, but requires that your merchants complete all signup fields. You use a URL with static parameters to direct the merchant to PayPal. You don’t have to call the REST API to pre-fill information, but you might have to whitelist the return URL.


Before you can use the Connected Onboarding API:

Integration steps

To use the URL option to onboard your merchants:

1. Required Place a PayPal signup URL on your site.
2. Required Whitelist the return URL.
3. Required Confirm your merchant's email address.
4. Optional but recommended Show your merchant account status.

Place a PayPal signup URL on your site

Add a link or button to your site that directs merchants to create a PayPal account, or to log into an existing PayPal account and configure it to accept payments. In the URL, pass the following parameters:

channelId The channel. Set to partner.
partnerId Your payer ID, which is your PayPal account number.
partnerClientId The partner's client ID.
returnToPartnerUrl The URL to return to your site. You might need to whitelist this URL.
partnerLogoUrl The URL to your logo. Can be displayed during the onboarding process. Applies only if the partner is not using in-context display through a mini-browser.
merchantId The unique ID of the merchant in your system. Required if the partner intends to use REST APIs to show the merchant’s account status.
productIntentId Set to addipmt.
features For the list of supported features, review our permissions page
showPermissions A Boolean that if set to true, shows permissions in the onboarding flow.
Note: PayPal generates permissions based on the feature list that you specify.
integrationType The type of integration between you and your merchants. To specify OAUTH_THIRD_PARTY, set to TO.

Here’s a sample URL:


Whitelist the return URL

To return the merchant to your site, ask your PayPal account manager to whitelist the URL. If you do not whitelist this URL, the merchant is redirected to the account setup page.

Confirm your merchant's email address

After you create the merchant account, the merchant receives a welcome email. To confirm the email associated with the account, the merchant should click the link in the email and follow the instructions.

Show your merchant account status

The following sample call and parameters shows the merchant’s encrypted account number (payer_id) and HATEOAS links that let you access the status of the integration:

GET /v1/customer/partners/partner_id/merchant-integrations?tracking_id=merchant_handle
  • partner_id. Your payer_id.

  • merchant_handle. The ID you created for the merchant when you shared customer data with the call to POST /v1/customer/partner-referrals.

The call returns the merchant ID and a HATEOAS link to access status data for the integration:

  "merchant_id": "RH6V5EPUPUW3S",
  "tracking_id": "karricepnoint1",
  "links": [{
    "href": "/v1/customer/partners/XJPHPNFGXYGG6/merchant-integrations/RH6V5EPUPUW3S",
    "rel": "get",
    "method": "GET"

Use the following HATEOAS link, which includes your partner_id and the encrypted ID of the merchant, to obtain the integration data for the specified merchant:

"href": "/v1/customer/partners/XJPHPNFGXYGG6/merchant-integrations/RH6V5EPUPUW3S"

Or, use GET to retrieve the status of the account:

GET /v1/customer/partners/partner_id/merchant-integrations/merchant_id

The response includes:

  • The payer ID of the merchant if the merchant has granted permission to access their account.
  • The tracking ID of the merchant, which is the ID that you created when you shared customer data.
  • The email confirmation status. The value is true or false.
  • A list of permissions that the merchant has granted you
  • The product for which the merchant has been onboarded (such as Express Checkout).
  • The product status, which is active or inactive.
  • Indicates whether the merchant is restricted from receiving payments. Value is true or false.

For example:

  "merchant_id": "T49KQUTWRGKBJ",
  "tracking_id": "Karrisunitrackingid",
  "products": [{
    "name": "EXPRESS_CHECKOUT"
  "payments_receivable": true,
  "primary_email_confirmed": false,
  "oauth_integrations": [{
    "integration_type": "OAUTH_THIRD_PARTY",
    "integration_method": "PAYPAL",
    "oauth_third_party": [{

When you send a transaction to PayPal for a merchant who has not completed PayPal account setup, the status of the transaction is set to pending. PayPal sends a PAYMENT.CAPTURE.PENDING webhook with the reason code Seller_setup_pending.

Once the merchant has completed PayPal account setup, PayPal sends these webhooks:

  • PAYMENT.CAPTURE.COMPLETED to indicate that the payment capture has changed from pending to completed.
  • MERCHANT.ONBOARDING.COMPLETED to indicate that the merchant has completed account setup. You can subscribe to webhooks to be alerted when a merchant's account setup is complete.

PayPal also sends the MERCHANT.PARTNER-CONSENT.REVOKED webhook when the merchant account is closed, or the account setup consents have been revoked.

For more information about these webhook events, see Webhook event names.


You have completed connected path onboarding.
