Webhook Event Payload Overview

Payload info

Webhook notification payloads are delivered using the application/json content type. The payload object contains all the relevant information about what just happened, including the type of event and the data associated with that event. Acrobat Sign then sends the payload object, via an HTTP POST request, to any endpoint URLs that you have defined as webhook URLs.

Payload size and truncation

The payload size is restricted to 10 MB. If an event generates a larger payload, a webhook is triggered but the conditional parameters attributes, if they’re in the request, will be removed to reduce the size of the payload. Also, a conditionalParametersTrimmed array object will be included in the response for this case to tell the client which conditionalParameters info is removed. The truncation occurs in the following order:

  • includeSignedDocuments

  • includeParticipantsInfo

  • includeDocumentsInfo

  • includeDetailedInfo

The truncation order is as follows:

  • Signed documents in a base 64 encoded format

  • Participant info

  • Document info

  • Detailed info

Truncation may happen, for example, on an agreement completion event if it includes a signed document in a base 64 encoded format as well or for an agreement with multiple form fields.

Basic webhook payload

All events include the following common payload attributes. Additional parameters returned along with specific event payload objects for particular keys are defined in the payload specifications for each event.

Parameter name

Type

Description

Possible values

webhookId

String

Webhook identifier of the webhook for which the notification sent

webhookname

String

Name of the webhook which was provided while creating a webhook

webhookNotificationId

String

The unique identifier of the webhook notification. This will be helpful in identifying duplicate notifications, if any.

webhookNotificationApplicableUsers

Object

An array of the details of the users for which this notification is delivered. For example: Say User A and User B are in a Group G1. Say User C is in Group G2, and both these groups and all 3 users are in Account A. Assume, group level “webhook W1” is registered on Group G1 and group level “webhook W2” is registered on Group G2. Now an agreement is sent by User A and to User B. And User B delegates the signing to User C. In the above case, the sign will generate only two notifications (corresponding to W1 and W2) for the delegation event. The current field for W1 notification will be an array of details of User A and User B. The current field for W2 notification will be an array of details of User C.
