We leverage Microsoft Power Automate for calling the CC API for various tasks without issues (e.g. get contacts, delete contacts, etc.). These have been manual, one-off runs of these processes using an access token generated through Postman. We want to automate these processes to run daily, which requires refreshing the access token with the process. However, making the POST to obtain a new access token fails each time with the following error. { "errorCode": "E0000021", "errorSummary": "Bad request. Accept and/or Content-Type headers likely do not match supported values.", "errorLink": "E0000021", "errorId": "oaerLte4bS6QKqfxodU6E_--w", "errorCauses": [] } The call is using the same parameters and headers as the call in Postman, so I'm not sure what the problem is. Obviously it is something specific with Power Automate and how it makes the POST call. URI: https://authz.constantcontact.com/oauth2/default/v1/token?refresh_token=[Refresh Token]&grant_type=refresh_token Headers: { "Accept": "application/json", "Content-Type": "application/x-www-form-urlencoded" } I'm wondering if anyone else in the community has encountered this and if you were able to work around this. Without being able to automate this step, we're stuck with a manual process.
