FAQ

Questions about Make API Call.

What does the Make API Call action do in Anthropic?
Makes a custom API call to any Anthropic endpoint with method, path, headers, and body. The escape hatch for newly-released APIs or fields that the typed actions don't yet expose.
What inputs does Make API Call require?
Required: Method, Path. 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 Anthropic 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 Make API Call support batch operations?
Yes. Run Make API Call inside a Loop node to process arrays. Tiny Command handles Anthropic's rate limits automatically so you don't have to throttle manually.
