Need a way to send ARB issue events (failed credit card processing, cancelled subscription, etc...)

[adamanetforum]

I've logged into the sandbox website. I've created my sandbox API keys and I've created a test user and a test subscription both with test credit card numbers.  What I don't see are ways to send test webhook notifications to my testing/stage server.  Is there a way to send test data simply by filling out a form that will use the key's I've created but with a made up customerProfileId so that I can see if the webhook works on my end, but using your authentication methods?

nah there’s no built-in form or button to trigger fake ARB webhooks directly from the Authorize.Net sandbox. what most people do is manually POST sample webhook JSON payloads to their own endpoint using something like Postman or curl, just copy the exact format from the docs and sign it with your sandbox signature key. the sandbox only sends real webhooks when an actual test event happens (like creating a test subscription and letting it fail, cancel, etc). so if you just want to test your server’s handling, sending mock requests yourself is the way to go.
