How can I test PayPal Express Checkout in Sandbox mode?

i tried to setup my shopify to use paypal Express Checkout, but i can’t log using my paypal sandbox account. so how am i gonna be able to run my tests using paypal ?

the only thing I found in shopify documentation relative to my use case is this:

Hi @ismailalabou - did you ever find a way to connect your paypal sandbox account? I’m facing the exact same problem.

hello there @simmsy ;

just connect/setup your PayPal account, under settingspayment.

(activate PayPal express checkout button)

let me know if u are still facing the same issue.
