I'm looking for help with an OAUTH setup for testing some APIs. I'm relatively new to this and I'm running into issues connecting my Shopify with OAUTH2. The error message I'm getting says my redirect URI isn't matching. If anyone has a bit of time to assist, I'd really appreciate it! I'm willing to offer $5-20 on PayPal for your help.

It sounds like you're on the right track! The redirect URI often needs to match exactly what you have configured in your OAUTH settings. Double-check that the URI you’re using matches what you’ve entered in your API platform. Sometimes even a trailing slash can cause mismatches.
Make sure the redirect URI in your code is exactly the same as the one set in your OAUTH application settings — even minor differences can lead to errors. If you're still stuck, posting your URI settings here could help others give more tailored advice.
