(Ruby) PayPal - Store Credit Card in Vault

Saves the buyer's credit card information to PayPal's vault. This avoids storing credit card details on your server and thus PCI compliance is no longer an issue.

Note: For sandbox calls, you can use the credit card numbers provided in your sandbox test accounts.

Note: This example requires Chilkat v9.5.0.65 or greater.

# Note: Requires Chilkat v9.5.0.65 or greater.

# This requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# A single REST object, once connected, can be used for many PayPal REST API calls.

# then it will be automatically re-established as needed.
