Hello,
Error 401
{
"error": "invalid_client",
"error_description": "Client Authentication failed"
}
when tryin to get Acceess Token.
Going by the book! Made a sandbox app, using Postman,
Authorisation: Basic Auth, entered username, entered secret
Body: x-www-form-urlencoded, grand_type: "client_credentials"
Entering data correctly, no spaces or anything like this. Tried entering secret "as is", with "-" symbols in between and without them. No effect.
Why do I get the error? Can anybody help, please?
