Invalid_client after authorize

[banyman]

Hello.
I created an application so that my clients can log in through PayPal. I need their data to generate a report in their account.

Authorization is successful, but when I return to my site, I see a Message on a white screen: invalid_client

What is the reason?

Good day @banyman,

Thank you for posting to the PayPal community.

App Review : Because Log in with PayPal involves sharing customer data, PayPal must review your app and approve it, before it can go live. All scopes require PayPal's approval.

• For live apps, once you finish configuring Log in with PayPal and select the Save button, your application is automatically submitted for review. The review process typically takes a few weeks.
• For sandbox apps, you don't need to submit your app for review. Log in with PayPal is enabled once you finish configuring your app in the Developer Dashboard and select the Save button.

Note: The app review process typically takes takes a few weeks. Plan for the app approval process accordingly, before your planned go live date.
