Best practise to chain API calls?

[CoenraadS]

Hello

I was wondering what is the best practice to implement something like

1. GET /api/foo/latest => returns id

2. GET API/foo/{id}

Either automatically running after each other or manually, both are fine for me.

Would setting the ID in environment variable be the way to go? I tried to also understand vars https://docs.usebruno.com/scripting/vars.html, but didn't really understand if they could be used across APIs

I'd do it like this:

Request 1. Execute GET /api/foo/latest, get the ìd out of the body and put it to the collection variable in the post-request script:

bru.setVar('app-foo-latest-id', res.body.id);

Request 2. Execute GET /api/foo/ request with the following pre-request script:

req.setUrl(req.getUrl() + bru.getVar('app-foo-latest-id'));

Collection variables work across different requests in the same collection.

Thanks, I just checked and I could also use {{app-foo-latest-id}} in the URL and it would also work with vars. Great!

Now instead of

script:post-response {
  bru.setVar('record_id', res.body.id);
}

you can do

vars:post-response {
  record_id: res.body.id
}
