Configuring a webhook callback for external applications

BMC Helix Innovation Studio supports webhook callbacks in an external application (only Adobe Sign and DocuSign is supported for now), so that the platform receives real-time notifications whenever an event takes place in the external application. These notifications can then be used to trigger specific rules or processes.

For more information, see Example of webhook callback in external applications


If you want to use the webhook callback in multiple applications, you must create a new configuration for each application. 

Before you begin

Adobe Sign
  • Ensure that you have an Adobe Sign account. 
  • Create your application in Adobe Sign. See  Create an application Open link  for the detailed steps.  
  • Get the Application ID from Adobe Sign. You get the application ID after  Creating an application Open link  and  Configuring OAuth Open link  in Adobe Sign. 
  • Make sure that you have a DocuSign account.
  • Generate the Hash-based Message Authentication Code (HMAC) key in DocuSign and copy it.
    See Setting up HMAC security with your application Open link in DocuSign.

    Important: The entire HMAC key is displayed only after it is created. Make sure that your save it securely.

To configure the webhook callback

  1. Log in to BMC Helix Innovation Studio and navigate to the Administration tab. 
  2. Select Integrations > Web APIs > Webhook callback configuration
  3. On the Webhook callback configurations page, click New

  4. On the Create New Callback Configuration page, in Configuration name, type a meaningful name for this configuration. 
    Example: Webhook-for-digitalSign


    For the callback configuration to work correctly, the configuration name must be the same in the development, QA, and production environments.

  5. From the Bundle name list, select the name of the application for which you want to use the webhook callback.
  6. From the Processor list, select one of the following options:
    • Adobe Sign
    • DocuSign
  7. To provide the external application's authentication credentials, perform one of the following steps:
    • (If you selected Adobe Sign), in X-ADOBESIGN-CLIENT ID, enter the Application Id that you received earlier.
    • (If you selected DocuSign), in DOCUSIGN_HMAC_KEY, enter the HMAC key that you received earlier.
  8. Click Save
  9. On the Webhook Call Configuration page, open the configuration that you created. 
    In Callback URL, the URL is populated automatically.

The following image is an example of configuring a webhook callback for Adobe Sign:

Adding the webhook callback URL in external applications

After you've configured the webhook callback, you must add the webhook URL (callback URL) in Adobe Sign or DocuSign so that the application can connect to BMC Helix Innovation Studio.

To add the webhook URL in Adobe Sign

In Adobe Sign, you can add the webhook URL in the following ways:

  • By using Adobe Sign REST API Open link
  • By using the Webhook UI. To use this method, perform the steps below:
  1. Log in to Adobe Sign. 
  2. Click the Account tab
  3. Select Webhooks, and click  Create a new webhook
  4. On the Create page, in Name, enter a name for the webhook. 
    Example: Webhook-For-Adobe 
  5. From the Scope list, select Account.
  6. In Url, type the Webhook URL that is displayed when configuring the webhook callback. 
  7. From the Events list, select the events in Adobe Sign for which you want to be notified. 
  8. In Notification Parameters, select the check boxes corresponding to the parameters for the selected events. 
  9. Click Save
    The settings are saved only if the Webhook URL is valid and publicly accessible.

You have configured the webhook callback in BMC Helix Innovation Studio and selected the events for which you want to be notified. 

To add the webhook URL in DocuSign

In DocuSign, you can add the webhook URL by completing the steps described in  Creating a Custom Connect configuration Open link  in DocuSign. 


When specifying the URL to Publish in DocuSign, make sure that you change the webhook URL received earlier from http://webhookurl/ to https://webhookurl.

Triggering a rule to perform actions in an application

You can use the webhook configuration to trigger a rule in an application developed on BMC Helix Innovation Studio after the selected events occur in Adobe Sign or DocuSign.

Learn how to trigger a rule based on a webhook callback.

Troubleshooting the webhook callbacks

The Webhook Callback Entry Data record definition contains the audit information of callbacks coming from the external application.

To view the audit data, in the Workspace tab, select the application in which you are using the webhook callback and select Records > Webhook Callback > Edit Data
