Copper CRM Custom API Request returning authentication error

I am attempting to integrate with Copper CRM, and I would like to fetch new activity_log details. This isn't one of the Copper CRM actions available, so I setup the following Custom API Request, where it specifically notes that I don't need to add authorization headers. However, when testing the request, it reports an authentication error:

As a workaround I can use the Pabbly API request action to make this same request, and manually add authorization headers--but that makes the workflow brittle and if I ever had to change the API key, someone would have to drill into the workflow and update on this particular step. How can I get this Custom API Request feature working?

Hello @JoshBeall,

Thank you for sharing the screenshot. Upon reviewing it along with the API documentation, it appears that the authentication headers have not been passed, which is why you are encountering the authentication error.

We recommend going to the API documentation, copying the cURL request from there, and then using the three-dot menu in your Custom API Request step to import the cURL. Once imported, please add the required authentication details under the headers that will be created.

Kindly try this at your end. If you still face any issues, please share the workflow URL with us along with the authentication details required in the API call, and we can assist in setting it up on your behalf.
