Device Flow Authorization Issue

[ChristopherF026]

Hello,

While I'm able to successfully authenticate other flow types I'm having a hard time getting past the first authorization step fo the device flow. I'm using Postman and have tried a few variations of the request imaged below. Any insight or advice would be greatly appreciated.

Hello ChristopherF026,

Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.

Based on the screenshot that you provided, the formatting of the call looks correct. I'd recommend checking the value of your API key to make sure it matches the key in your account settings and verifying that there are no hidden spaces or returns in the value.

If that does not resolve the issue, could you please reach our team directly/securely via email at webservices@constantcontact.com (referencing case #33507168) and provide us with the API key that you are using to make the request, the full request(s) where you are receiving the response (including URL, headers, timestamp, and request body), and the full response body so that we can better assist you in identifying the root cause of the issue?

Please have a look and let us know if you have any other questions!

Thank for your help. I was typing up a response email and reviewing what I was sending via Postman. Turns out, the request I was working with was inheriting its authorization from the collection that was using a different authorization type. Turning this off corrected the problem.
