Redirect URI mismatch.","error":"invalid_request"

I’m getting the error ‘Redirect URI mismatch.",“error”:“invalid_request”’, I believe I have the correct URIs specified in the portal

Redirect URI mismatch.",“error”:“invalid_request”

Which App Type (OAuth / Chatbot / JWT / Webhook)?

Which Endpoint/s?

How To Reproduce (If applicable)
I’ve got an authorization code from hitting the API, I am trying to retrieve the access tokens.

Screenshots (If applicable)

Additional context
I also cannot create a publishable URL, as it claims I haven’t set my OAuth redirect URL, which I have, or at least, I think I have, as per the screenshot.

Hi @mark3, localhost cannot be used for Redirect URLs. We suggest using something like ngrok for development to expose a public link for your local server.
