I've been trying to get a connection working using the Data API. (Currently, using FileMaker Server version 16.)
Here are the settings in Postman:
When I send the request, I receive the result shown at the bottom. The Postman Console shows this:
I know that I'm missing something, but I can't see what it is. If I try using Rested, it builds a slightly different set of headers, but the response is that there is an invalid header.
At this point, I just want to get a response from the server with a token, so that I know that everything is working.
The server does have the API turned on, and the user's privilege set allows connections through the API.
