}Webhook payload examples FAQ
- Are these real field names, or a mockup?
- Real — the field list for each event comes straight from the same registry the API validates against and the OpenAPI spec renders from. Only the example values shown are illustrative.
- Is the signature shown a real, working signature?
- Yes — it’s computed with the same HMAC-SHA256 scheme SkedCast’s webhook delivery actually signs with, over the exact JSON body shown, using whatever secret you type in.
- Can I use my own webhook secret to test this?
- Yes — paste your real endpoint secret and the generated signature will match what your own receiver should compute for that body, useful for testing your verification code.
- Does this actually send the webhook anywhere?
- No — this only builds and signs an example locally in your browser; nothing is sent to any endpoint. Use the "Test webhook" action in the console to send a real test delivery.
- Why does the body change when I pick a different event?
- Each event carries a different set of real fields in its `data` object — the generator rebuilds the example to match exactly the fields that event actually sends.
- What headers does a real delivery carry besides the signature?
- X-SkedCast-Event (the event type), X-SkedCast-Delivery (a stable id to dedupe retries on), X-SkedCast-Attempt (a 1-based retry counter), plus the Standard Webhooks headers (webhook-id, webhook-timestamp, webhook-signature) sent alongside for receivers that use an off-the-shelf verification library.
