About

Chains multiple API requests into a reusable scenario with extracted variables, assertions, and execution logs. It helps QA and API teams validate end-to-end flows without leaving the browser.

Accepted input

Each collection contains named requests with params, headers, a raw body, assertions, and environment-specific base URLs or bearer tokens. Shared {{VARIABLE}} placeholders resolve from request context and the active Kalp environment.

How to use

Create or select a collection, then add requests for each step in the workflow.
Configure params, headers, body, and assertions for the active request.
Run a single request or the full collection to inspect status codes, extracted values, and assertion results.
Save collections locally so the scenario reloads the next time you open the tool.

Tips

Use extracted response values in later requests with {{step.response.path}} placeholders.
Seed new collections from the built-in example to learn the chaining model faster.
