Webhooks
POST /v1/webhooks/{id}/test — Send a Test Event
Deliver a test event synchronously and see the exact HTTP status and error your server returned.
POST
Send a test event
Sends a
webhook.test event inline and hands back what actually happened — the real response status and error text. Use it to confirm your signature check passes before you depend on push in production.
A failed test still returns HTTP 200 here; read the delivered field, not the status code.
Authentication required. Send your key as Authorization: Bearer csb_pub_.... A read key is enough — managing webhooks moves no money.
