PayPal
Enable PayPal as one of your payment service providers in OpenPay.
Enable Vault Access
Our PayPal integration uses PayPal API v3 and Vault feature to manage payment tokens. You need to enable Vault access before processing transactions. Please follow the following steps to enable Vault in your PayPal developer account.

Go to App & Credentials and go to the app you want to integrate with.

-
Once you’re in the app’s page, scroll down to see “Features” section

-
Enable “Vault”

Click “Save Changes”.

If this doesn’t work for you for some reasons, please reach out to PayPal support requesting vault v3 API access.
