HTTP Request
The mechanism by which most modern automations communicate with external services. A webhook sends an HTTP POST; an API call sends an HTTP GET or POST. Understanding this helps diagnose integration failures.
Expert insight
When a workflow fails, the HTTP status code it got back tells you almost everything. A 401 or 403 means an auth problem (expired token, wrong API key), a 429 means you've hit a rate limit, a 500 means the problem is on the other service's end, not yours. Building automations that log the actual status code and response body on failure, instead of just "step failed", turns a 30-minute debugging session into a 30-second one.
In a real workflow
When a tool has no ready-made node, an HTTP Request node calls its REST API directly with the right headers.
Common mistakes
- Ignoring status codes and treating every response as success.
- Hard-coding tokens in the request instead of using credentials.
Complexity level
Requires some familiarity with automation concepts.
