I need some help with configuring OAuth for my app
My sandbox application ID is:
`sandbox-sq0idb-dAG9tgZj7ah-E-RLt1-f9A`
I'm currently testing the OAuth flow in the Sandbox environment, but I'm consistently receiving a 400 Bad Request error, even though I've followed the OAuth documentation step by step.
The authorization URL I'm using is:
https://squareupsandbox.com/oauth2/authorize?client_id=sandbox-sq0idb-dAG9tgZj7ah-E-RLt1-f9A&redirec...
When I open this URL in the browser, it immediately loads a white page (blank page). In the browser's developer console, I can see that the authorization request returns a 400 response.
I've verified the OAuth configuration based on the documentation, but I'm unable to determine what is causing the request to fail.
Could you please help me identify what might be wrong with my OAuth request or application configuration? If there are any common misconfigurations or additional checks I should perform, I'd really appreciate your guidance.
Thank you!
