Unable to authenticate HubSpot API with OAuth 2.0 using Authorization code

Hi,

I having problems adding HubSpot's API to ION API with OAuth 2.0 using Authorization code. When I'm trying to Authorize I get the error "Error decoding AuthCode State". I can run the API directly from Postman so I know my set up works and the account is set up correctly.

Anyone who has experienced something similar or have an idea of what my issue is?

I get redirected correctly to HubSpot and using my credentials to log in, but when I get sent back to ION API I get the following message:

HI,

Can you please try with the below option.

Client Authentication : Header and remove scope parameter value

and also try client auth:body and remove scope parameter.

Hi Satish,

Thanks for your reply!

Unfortunately, your suggestion didn't work. It's required to send at least one scope parameter, but I tried to set it to the minimum "OAuth" scope. I've also tried to switch client authentication to the header. But, still the same error message.

Any other ideas are much appreciated!

HI,

Could you send the screenshots on how you were able to connect thru Postman API. Based on that we can configure the ION API.

Thanks,
