I'm trying to create a Subscription, I'm going through the steps here and I have created a PayPal app, and am now on Step 2: Get an access token, I downloaded Postman, and I'm trying to follow the steps here but, I'm stuck on Step 3. I guessed what Step 2 and was and did this.
I'm getting an error message and need help on what I did wrong.
Can anybody help me with this please?
