Returning only specific fields via Bitbucket API

[Esther Strom]

I'm trying to return a simplified list of all of our repos via API. When using the unmodified endpoint (https://api.bitbucket.org/2.0/repositories/{workspace}) I get something that looks like this:

That's just a single repo; we have over 800. All I really want from this is the full_name value. 

The API's partial-response documentation

indicates that there are three ways to get a partial response: remove specific fields, add additional fields, or return only specific fields. That last one is what I want, but I can't figure out how to do it. 

There are too many fields to use the ?fields=-links (or whatever field name) syntax, but the only example they have of "return only specific fields" is a json array, which has both field names and values. I don't want to filter things based on values; I want all repos returned, but only the single piece of info from each repo.

Can anyone help me out? I'm testing it in Postman; here's what I've tried so far.  All of them return the same full response as shown above. (The obscured part of the URL is our workspace name.)

You have to tell the api where the "full_name" or links field is.

In this case, it's inside "values"

try with ?fields=values.full_name

[Esther Strom]

Thanks! Because the he partial response documentation specifically mentions using the "+values.destination.repository.owner" format, and since full_name is on the same level in the json hierarchy as owner, I thought I needed to use the same format. Your way works!

[Peter-Dave Sheehan]

If you were returning a single repository, then ?fields=full_name would work to only show that field.

Frankly, I figured it out with trial and error and it's when i tried to retrieve a single repository that I saw that the ?field worked. All prior attempts were causing empty objects to be returned.
