What server response to report, following a link to a third-party site?

Question

Search Engine Optimization

The site has a payment button for PayPal with a link like this
/post-id/donate/
On the server I collect the necessary data and make a redirect to the payment form in PP
From the beginning I gave 307, Yandex began to swear at the status, then I did 302, now it writes

The page redirects the robot to LINK . Check the indexing of the redirect target.

This is fine? Or do you still need to give some other status?

Answer 1

Close this page from indexing in robots.txt, it is of no practical use either for the search engine or for the visitor.
