PayPal with login for authentication

[sanket07]

Hi, support

I am a developer and set up my site with PayPal authentication for user login.

I have set up all codes (PayPal SDK) and also setup PayPal APP in my sandbox account but I tired of the error https://prnt.sc/it724w

=> Looks like this action is not supported. Please return and report this error so that we can support it in the future. (invalid client_id or redirect_uri)

I have many time check all details but same error appear

Please check me what am I wrong?

Thanks.

Got the same error recently, did you set up the redirect uri in your apps "Return URL"-list? It has to be the full url with get variables.

Then it could take a long time for the change to take effect

I have same issue and wonder to know why Paypal take a lot time to take this affect??? So waste of time for just a sandbox implementation

How long you guys took to make this work? I got everything setup for 2 days now, and so far nothing
