Paypal error during checkout
It may be because 'API APP ID' saved while configuring the module is wrong https://prnt.sc/nzvpvv.
Please note that in order to use our Paypal Adaptive module, you need to get the credentials from Paypal.
Unfortunately, as mentioned, Adaptive Payments are permanently unavailable starting December 1, 2017, as per the information from PayPal.
So you need to directly contact PayPal and ask them for API APP ID if they can provide you with the credentials (API APP ID) for the same or not.
I suggested you install the Other Paypal module from the Module and Services Tab.
After the installation of the module, you will need to put in your details.
Then you will be able to accept payment through Paypal
Module will automatically show the availability of the module for your default country. Currently, we have only two above paypal modules available.
so it means there is no way that we can integrate PayPal gateway
For Paypal Adaptive module, you need to get the credentials (API APP ID) from Paypal. So you need to directly contact PayPal and ask them for API APP ID if they can provide you with the credentials (API APP ID) for the same or not.
If you get the API APP ID then you can use it.
For the other Paypal module, As it is not supported in your country then you can not use it.
