API Explorer (genesys.cloud)
I almost always use the API explorer for testing stuff before moving to SDK but - I'm sure that before the Explorer was migrated to its current format, there used to be documentation about the acceptable values for most fields.
Does that documentation still exist somewhere?
For example, I'm looking at the Speech and Text Analytics Transcript search API. One of the fields is "returnFields", and it's looking for a list of strings. How can I know which strings are valid to put in there?
I'm sure it is documented somewhere, I just can't see it.
The current API Explorer has everything the old one did, and a lot more. There was a lot of information missing from the old one. If you look in your screenshot at the first property in the request, it documents Valid values.
The returnFields property appears to simply not have any documentation. It doesn't appear to be referenced in the articles for speech and text analytics either. Please open a case with Genesys Cloud Care to report the missing documentation and to request the list of values that should be documented there. API documentation requires code changes in the product, so it must be reported via Care for fixing.
Just to complement Tim's answer.
Although that is not the full description of the returnFields values, the article on Transcript search mentions 3 of them: conversationId, communicationId, topic
