Webhooks Management API

The PayPal REST APIs use webhooks for event notification. Webhooks are HTTP callbacks that receive notification messages for events. After you configure a webhook listener for your app, you can create a webhook, which subscribes the webhook listener for your app to events. The notifications namespace contains resource collections for webhooks.

Webhooks (resource group)

Use the /webhooks resource to subscribe your webhook listener to events, list webhooks for an app, show details for, update, delete, and list event subscriptions for webhooks.

List webhooks

GET/v1/notifications/webhooks

Lists webhooks for an app.

Query parameters

anchor_type
enum
Filters the webhooks in the response by an anchor_id entity type.
Possible values: APPLICATION,ACCOUNT.

Sample Request

curl -v -X GET https://api-m.sandbox.paypal.com/v1/notifications/webhooks \
-H "Content-Type: application/json" \
-H "Authorization: Bearer Access-Token"

Response

A successful request returns the HTTP 200 OK status code and a JSON response body that lists webhooks with webhook details.

link_description

href
string

method
enum
The HTTP method required to make the related call.

pairs

patch

`op`

enum

required

The operation.

The possible values are:

add.
Depending on the target location reference, completes one of these functions:
- The target location is an array index. Inserts a new value into the array at the specified index.
- The target location is an object parameter that does not already exist. Adds a new parameter to the object.
- The target location is an object parameter that does exist. Replaces that parameter's value.
The value parameter defines the value to add. For more information, see 4.1. add.
remove. Removes the value at the target location. For the operation to succeed, the target location must exist. For more information, see 4.2. remove.
replace. Replaces the value at the target location with a new value. The operation object must contain a value parameter that defines the replacement value. For the operation to succeed, the target location must exist. For more information, see 4.3. replace.
move. Removes the value at a specified location and adds it to the target location. The operation object must contain a from parameter, which is a string that contains a JSON pointer value that references the location in the target document from which to move the value. For the operation to succeed, the from location must exist. For more information, see 4.4. move.
copy. Copies the value at a specified location to the target location. The operation object must contain a from parameter, which is a string that contains a JSON pointer value that references the location in the target document from which to copy the value. For the operation to succeed, the from location must exist. For more information, see 4.5. copy.

test. Tests that a value at the target location is equal to a specified value. The operation object must contain a value parameter that defines the value to compare to the target location's value. For the operation to succeed, the target location must be equal to the value value. For test, equal indicates that the value at the target location and the value that value defines are of the same JSON type. The data type of the value determines how equality is defined:

Type	Considered equal if both values
strings	Contain the same number of Unicode characters and their code points are byte-by-byte equal.
numbers	Are numerically equal.
arrays	Contain the same number of values, and each value is equal to the value at the corresponding position in the other array, by using these type-specific rules.
objects	Contain the same number of parameters, and each parameter is equal to a parameter in the other object, by comparing their keys (as strings) and their values (by using these type-specific rules).
literals (`false`, `true`, and `null`)	Are the same. The comparison is a logical comparison. For example, whitespace between the parameter values of an array is not significant. Also, ordering of the serialization of object parameters is not significant.

For more information, see 4.6. test.

from
string
The JSON Pointer to the target document location from which to move the value. Required for the move operation.
path
string
The JSON Pointer to the target document location at which to complete the operation.
value
number,integer,string,boolean,null,array,object
The value to apply. The remove operation does not require a value.
