FAQ

Questions about Raw API Request.

What does the Raw API Request action do in Slack?

Makes a raw authenticated call to any Slack Web API method. The escape hatch for endpoints not yet covered by a dedicated action.

What inputs does Raw API Request require?

Required: Endpoint. Every input accepts a static value or a variable from any upstream node in your workflow.

Can I use dynamic inputs from earlier workflow nodes?

Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.

What happens if Slack returns an error?

The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.

Does Raw API Request support batch operations?

Yes. Run Raw API Request inside a Loop node to process arrays. Tiny Command handles Slack's rate limits automatically so you don't have to throttle manually.
