I have been working on paypal preapproval flow to be used in one of the web application after getting preapproval key and paykey I have the following URL
https://www.sandbox.payp...ey=PA-62N95909CR813734Y to be executed by paypal embedded payments javascript in order to get preapproval pop-up from paypal but in both the cases (when URL containing paykey only and containing both paykey and preapproval key as well) I have been getting paymet pop-up, there is no pop-up for preapproval.
How do I can implement preapproval flow?
