How Do You Pass Data Between Chained API Requests? Asked LTIMindtree Final Round.

Passing data between chained API requests means taking some value from the response of one API call and using it as input in a subsequent API call. 1. Common Use Cases Passing authentication tokens from login API → data API. Using IDs created in one request (POST) → fetching/updating in another request (GET/PUT). Chaining multiple dependent workflows (create → update → delete). 2. General Steps Send first request and store required value from its response (e.g., token, userId). Save value in a variable (environment, global, or code variable). Use variable in the next API request’s URL, headers, or body. Advanced Patterns Dynamic chaining in loops: Iterate over multiple IDs from first response. Data-driven chaining: Read input from external files but still feed in chained values. Multi-step chaining: e.g., Create → Verify → Update → Delete. Error handling: Stop chain if an earlier API fails.
