Partially updates a subscription's event families, events, or transport configuration. Only fields included in the request body will be modified.

Finding Your Customer Subdomain

Your subdomain is found in your Avaya Infinity portal URL and is required for all API calls.

Example: If your portal URL is:

https://core.avaya1234.ec.avayacloud.com/app/core-config-ui/

Your subdomain is: avaya1234

To use this API:

1. Find your subdomain from your Infinity portal URL (as shown above)
2. Get your Bearer token using the EVENT_NOTIFICATION client credential (see Authentication below)
3. In the API explorer on the right:
   • Click on {customerId} in the URL field and replace it with your actual subdomain
   • Paste your Bearer token in the Credentials section
   • Enter the subscriptionId and provide only the fields you want to change

Authentication

This endpoint requires a valid OAuth 2.0 Bearer token. To get started, contact Avaya Support to request a client_id and client_secret provisioned with the EVENT_NOTIFICATION scope.

Once you have your credentials, generate an access token and include it in the Authorization: Bearer <token> header of each request.

Important Notes

• All fields are optional — only fields explicitly provided will be modified.
• Returns a 404 if no subscription exists with the specified ID.

Rate Limiting

• This endpoint implements DOS protection and rate limiting. If you receive a 429 Too Many Requests response, implement exponential backoff before retrying.
