I am trying to setup an oauth authorization in Postman to retrieve an access token to use to interact with Hubspot APIs. After inputting my app information and clicking “Get New Access Token”, I am prompted to login to my developer account. When doing so, I am granted this error. Has anyone ever seen this?
Hey, @calebgib 
Thanks for your question. To confirm, you are using this option in Postman, correct?
Additionally, are you trying to log in into an App Developer account? Or an App Test Account?
If not, can you clarify what account type you are trying to use, please?
Best,
Jaycee
Jaycee,
I was not using the correct Authorization type. After changing that, I was able to get an access token and used that to make API calls. Thanks for your help.
