Process a purchase transaction using transaction and company tokens along with card details or the token for a previously tokenised card.
This endpoint performs either an immediate charge or pre-authorization based on request.

About Purchase Transactions

Purchase transactions support:

• Immediate payment processing or pre-authorization
• Card tokenization for future use
• 3D Secure authentication
• Surcharge calculation
• Customer reference tracking

Use this endpoint for:

• Immediate payment processing
• Pre-authorized transactions (capture later)
• Card tokenization and storage
• 3D Secure enabled transactions

About 3D Secure

The decision to require 3DS Secure authentication ultimately rests with the card issuer. It is recommended an authentication redirect url is provided even in case of 3DS not requested.
Failure to do so may result in the transaction being declined.
