API Playground: Chain API responses as inputs to other API calls

[mayank2yk]

It would be great to have the ability to chain API calls within the API Playground. Specifically, I'd like to use the response value from one API endpoint as the request parameter/body for another API endpoint.

Use Case:
When testing multi-step API workflows, users often need to:

Call an initial endpoint (e.g., create a resource)
Take a value from the response (e.g., an id)
Use that value as input for a subsequent API call (e.g., get resource details)
Currently, users must manually copy and paste values between API calls, which is tedious and error-prone.

Proposed Behavior:

Allow users to reference response fields from a previously executed API call as input parameters for another API call
Support mapping response fields to request parameters/body fields
Enable multi-step API workflow testing within the Playground
This would significantly improve the developer experience when exploring APIs with dependent endpoints.

Adding more context from real-world usage:

We're building a multi-step API workflow system (similar to orchestrating dependent endpoints like create → fetch → enrich).

Currently in the Playground:

• We call endpoint A -> get response (e.g. ID)
• Manually copy that into endpoint B
• Repeat for each step

This becomes:

• Error-prone
• Slow for iteration
• Hard to demo or test flows end-to-end

What would help:

• Referencing previous responses like {{step1.response.id}}
• Mapping response → request fields visually or via variables

This would essentially unlock:

• Multi-step workflow testing
• Faster debugging of dependent APIs
• A Postman Flows–like experience inside Playground

Happy to share a quick prototype / mock if helpful.
