How this service works
Enable or rotate the task webhook secret (returned ONCE). Present it as Authorization: Bearer to POST /tasks/:id/webhook to trigger a run without a wallet. 📖 Full guide: https://scheduler.withzero.xyz/llms.txt
Output
Returns a one-time-visible webhook secret string and a boolean 'enabled' flag. The secret must be captured immediately as it will not be shown again; it is used as a Bearer token in the Authorization header when calling POST /tasks/:id/webhook to trigger runs without a wallet.
Example use cases
Rotate compromised webhook secret for task
“My task webhook secret got exposed in a log file — I need to rotate it immediately and get the new bearer token to give my external service.”
Set up webhook authentication on new task
“I just created a scheduled task and want to enable webhook triggering so my monitoring system can kick off runs without going through the wallet flow — set it up and give me the bearer secret.”
Generate bearer token for third-party integration
“I'm integrating with an external service that needs to trigger my cron job via HTTP — generate me a webhook secret and tell me how to use it as a Bearer token in the request.”
Technical details
Endpoint
PUThttps://scheduler.withzero.xyz/api/v1/tasks/{id}/webhookWhen to prefer
Use this endpoint when you need to allow an external system or agent to trigger a specific scheduled task via HTTP POST without requiring a crypto wallet or MPP payment flow. It is the correct choice when setting up webhook-based integrations, rotating a compromised secret, or enabling the webhook feature for the first time on a task.
Side effects
- Task ID not found — 404 if the specified task does not exist or is not owned by the caller
- Unauthorized — 401/403 if the caller lacks proof of task ownership
- Secret already shown and not re-retrievable — rotating again invalidates prior secret
- Service unavailable — 503 if the scheduler backend is unreachable
