Webhook

Webhooks are available via application and profile level subscriptions. This set of APIs allows you to create, list, and delete subscriptions as well as test your webhook subscription endpoints.

For more information on creating and managing webhooks, and specific event types, please see Webhooks & Notifications.

The Webhook Resource

All webhook event notification payloads have the same high-level structure. Top-level properties are common to all events. The data property is an object that can contain various properties. The exact properties that the data object contains depends on the event type and schema version of the event.

Common Properties

dataobject

Event type- and schema version-specific details

subscription_idtext

ID of the webhook subscription that triggered the event notification

event_typestring

Event type (what event happened in our system)

schema_versionstring

Schema version (what notification structure is being used to model the event)

sent_atdatetime

When the event notification was sent from our system

Webhook Payload

Test Notifications for Application Subscriptions

Test notifications can be generated for existing application subscriptions using the API.

Test notifications will have the correct structure for their source subscription's event type and version, and will contain "dummy" data. These data include random UUIDs, entity IDs of zero, current dates and times, and hard-coded status codes.

Test notifications are delivered with the usual notification HTTP request headers, including a unique delivery ID for the notification, and a "test notification" flag set to true. You can check for the presence of this test flag to determine that an incoming notification is a test notification which should not be processed as real data. See the section Event HTTP requests for more information on request headers.

When test notifications are created with the API, they are queued for sending in the same way as non-test notifications. This means that there may be some delay in notification delivery, and delivery failures will result in attempts to redeliver the notification later. The API returns the delivery IDs of the notifications that have been successfully queued for sending, which can be correlated with the delivery ID header values for notifications you later receive.

Please note that this test notification API is only available for application-based subscriptions. Profile-based subscriptions do not currently support this testing feature.

curl -X POST "https://api.sandbox.transferwise.tech/v3/applications/{{clientKey}}/subscriptions/{{subscriptionId}}/test-notifications" \
