Websites - Changing shop payment provider
You can use a PayPal and/or Stripe account to receive payments from customers. If you enable both Stripe and PayPal accounts, customers can choose which service to use.
You can select which of your linked accounts is used with each shop, so if you have several different shop websites you can choose different payment accounts for each one.
You can also add testing accounts and switch your shop to them to make test transactions.
To add or edit a shop's payment provider, go to the Sales tab from the website screen. Select your chosen account from the dropdown and click Save.
If you can't see the account in the dropdown, make sure you've connected the account in Services first.
