I followed all the steps to access the APIs service, I got the PUBLIC_KEY the PRIVATE_KEY and Application ID.
I downloaded Postman APIs and replaced the values.
But I receive when i call https://api.tcgplayer.com/token
“error_description”: “Incorrect credentials”
I also saw the example created on the following link:
and I eliminated from the Headers X-Tcg-Access-Token
but nothing always returns to me the error written above
