why do you send startTimestamp with headers? its closure-like, you can use startTimestamp directly

How to record response time for more than 1 API calls on one page? I have 3 API calls. I want to sum of all 3 response time and show in front-end. Any suggestion?

Are you running them sequentially or in parallel?

[pathikvejani]

parallel.

You could possibly use the CombineLatest creation operator to bundle the observables, and this will give you access to the time taken by each request, in the header and then depending on how you want to handle it, you can calculate how long it took to execute the request i.e. take the earliest start timestamp and the latest timestamp and subtract the two.
