When to use it
Every journey that makes API calls is built from HTTP request steps. You’d add one any time you need to:- Call an endpoint as part of a multi-step workflow
- Set up state (create a resource) before testing something downstream
- Validate a request/response pair against acceptance criteria
- Pass a value from one response into the next request
Key concepts
Request template. Each step is backed by a request template from your library. The template defines the HTTP method, path, headers, body shape, and recommended parameter configuration. The step inherits that definition and lets you configure how each value is supplied at run time. Value sources. A request has many parts — URL, path params, query params, headers, body fields, auth. Each field can be independently wired to a value source. See Step values for the full list. Step outputs. After a request runs, you can capture values from the response (status code, body fields, headers) and make them available to later steps. See Step outputs. Assertions. You can attach acceptance criteria to a step. Assertions run after the response arrives and determine whether the step passed or failed. See Assertions.How it works
Add a step
In Build mode, add a step to the journey canvas and select a request template from your library. The template populates the step with the request definition.
Configure values
Open the step’s value configuration. For each field that needs a value (path params, headers, body, auth), choose a source: run input, variable, step output, hard-coded, environment, secret reference, or “me” value.
Capture outputs (optional)
If a later step needs data from this response — an ID, a token, a computed field — define a step output to extract it. Name the output so you can reference it downstream.
Attach assertions (optional)
Add assertions to check the response: status code, body fields, headers, response time. Assertion failures mark the step as failed in run output.
