I have the latest version of ECT.
I am trying to setup the latest USPS API.
On the ECT page it says to follow the first 4 steps, the 4th step on the USPS is generate Oauth token. I assume tha tECT will do it in hte background, and all I need to do is to generate the Client and Secret ID, correct?)
So I generated the Client ID and Secret ID.
I put it in the ECT page.

But I am getting this error upon checkout
"Error, invalid response from https://apis.usps.com/oauth2/v3/token (403)"

What am I doing wrong?
Please help!

Hi there
That really does sound like your Consumer Key and Consumer Secret are wrong. My keys are 49 and 65 characters and are yours something similar?

Hi Vince, yeah! they are long keys.

And what about the 4th step, where it says to generate the OAuth token. Do i need to do anything there?

Thank you
