action.fetch_webhook · 2.8.0

Browse all entries

Requirements and availability

A reachable endpoint you control; correct authentication/JSON supplied explicitly.

Picker contexts: automation, timer, command, pad.

Behavior

Resolve URL/body through the provided global variable resolver; the simple event-key fallback is used only when that resolver is absent. Blank URL does nothing; method defaults GET. POST/PUT may send body; headers are literal JSON and malformed headers are ignored. Request failures are logged; response body is not exposed to later actions.

Configure in the app

Open: Do → Advanced Actions (commands only) → Add action

Steps

Choose action category Utilities, select Fetch webhook, and click Add action.
Expand the action card. Configure the Fields below; check Editor defaults for your context and any operation-dependent fields.
Choose resource values from real app pickers. Set output Platform separately from the trigger Where setting when the action offers it.
Use Move action up / Move action down to position this action, then save the containing command, automation, timer or SheevPad button.

Limitations

Picker availability does not supply missing event variables. Check prerequisites and originating provider.
An action return value is not automatically a sequence variable. Only documented producers create template outputs.
