Delete Subscription

Permanently deletes an existing subscription by its subscriptionId. Once deleted, the subscription cannot be recovered and will stop delivering events immediately.

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 of the subscription to delete

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.

POST https://core.avaya1234.ec.avayacloud.com/auth/realms/avaya/protocol/openid-connect/token
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials&client_id=<your_client_id>&client_secret=<your_client_secret>&scope=EVENT_NOTIFICATION

Important Notes

• This action cannot be undone. Confirm the correct subscriptionId before proceeding.
• Returns 204 No Content on success — no response body is returned.
• Returns a 404 if no subscription exists with the specified ID.

DOS Protection & Rate Limiting

• This endpoint implements DOS protection and rate limiting.

Security Implementation Guidelines

• Never expose your client_secret or Bearer token to client-side applications.
• Implement proper error handling — avoid surfacing internal error details to end users.
