Worked fine yesterday and no code has changed. I come in this morning and the exact same code on the exact same page is giving the following error message:
Error: Error: Request to post https://www.sandbox.paypal.com/v1/oauth2/token failed with 400 error.
{
"error": "invalid_client",
"error_description": "Client credentials are missing"
}
The client credentials are definitely not missing, worked fine yesterday, and are still valid.
