We are trying to use Adaptive Payment from PayPal and prepare the Production environment but for payment transfer from sender to the receiver we need X-PAYPAL-APPLICATION-ID to pass in API Header. How we get the application ID?
We have created the application in the PayPal account, but we cannot find the application ID.
Unfortunately, the Adaptive Payments product is no longer available for merchants. It has been deprecated and replaced by our PayPal Commerce Platform product for Marketplaces. Take a look at this here.
