I have a Custom Field/Column under Projects in my PWA site. I am trying to create a REST API call that will add a new Project to PWA. I have a column called "Project Departments" and I cant seem to figure out how to add data to that column.
Here is the Column info I retrieved from a separate REST API call.
Here is my attempt at using the "InternalName". I have also tried using the "Id" number but I keep getting the error "does not exist on type 'PS.ProjectCreationInformation'. Make sure to only use property names that are defined by the type"
How can I add text/info to this custom column from this REST API call?
I could not get the above method to work for any custom fields...it only worked for the 3 standard fields you listed. You should be able to ADD the project and then make a second call to update the custom fields using my method in the link.
If you check out my link here, I spent some time working with Custom Fields to come up with a solution.
We're still running it 2x a day every day to update our custom fields.
