Create Custom Fields


I am a developer working on an integration for a client. I have a test instance of Concur with their data. When I go to create an expense report through the UI, I can see that they have two custom fields: client and project.

It’s not clear to me from the API documentation how I can add values to either of these custom fields. For example, how to add a client to the client custom field, or a project to the project custom field.

I’ve looked as deeply as possible through the API docs. Can someone share a link to the appropriate documentation? An example POST request would be even more helpful!
