Frequently asked questions
How is this different from a real delivery?
How is this different from a real delivery?
Only the data. The payload carries
"test": true and synthetic events, but it travels the identical code path with the same headers, the same HMAC signing and the same timeout. If your verification passes here it will pass in production.Does a test move the watermark?
Does a test move the watermark?
No. A test fire never advances the watermark and never consumes real events, so you can run it as often as you need while building your receiver.
Is there a limit?
Is there a limit?
Roughly 10 test fires per hour per key.
