Updating PROJECT custom field values

Hi there,

I am wanting to update project custom field values, which I assumed would be a similar approach to updating deal custom field values, see Updating Custom Fields’ Values

I’ve tried calling the API Endpoint Log in with a payload of:

{
  "348c1f87c8affa2dbf27174d1f73294eb4306443": "my field value"
}

where 348c1f87c8affa2dbf27174d1f73294eb4306443 is my custom field key

  1. If I call it using PUT Method, using typical application/x-www-form-urlencoded submission, the response is Unsupported Media Type: application/x-www-form-urlencoded
  2. If I call it using PUT Method with JSON payload (Content-Type: application/json), I get a response of Internal Server Error (ce947d6c-25aa-4b19-b05c-f48755641d33)

Given projects is a fairly new module, Im guessing this isn’t fully implemented yet? If not, do you have this endpoint / feature in your API roadmap? Or does it exist, but its just not documented yet?

Thanks,
Travis
