How Each One Works
- UPG: you send one standardized request (token, amount, operation, PSP credentials) to a single PCI Booking endpoint. PCI Booking builds the full PSP request, inserts the card data, sends it to the PSP, and returns a normalized result.
- Token Replacement: you build the destination’s request yourself, exactly as its API defines it, with tokens where card data belongs. PCI Booking acts as a transparent proxy: it replaces the tokens with real card data in transit and forwards your request unchanged.
Comparison
When Token Replacement Is the Right Choice
Token Replacement is the general-purpose tool for delivering card data to any third party. Reach for it when:- The destination is not a PSP. A hotel, OTA, channel manager, or supplier API that needs card data inside a booking message can only be served by Token Replacement - the UPG does not apply.
- Your PSP is not yet among the UPG’s 100+ integrations. Use Token Replacement as a temporary stopgap, and at the same time ask us to add your PSP to the UPG - customers can request new UPG integrations at any point, at no cost. Once the integration is live, switch to the UPG and retire your replacement profile.
- You need a PSP operation the UPG does not support. Before building it on Token Replacement, contact support@pcibooking.net and tell us what you need - we actively enhance the UPG based on what the market needs, and we may be able to add the operation for you.
Recommendation: if you are sending card data to a PSP to process a payment, use the UPG. Token Replacement exists for delivering card data to arbitrary third parties; using it for PSP traffic means taking on integration and maintenance work that the UPG already does for you. The choice also determines who can help when something breaks: on the UPG we own the integration, so we can investigate issues on our end, guide the conversation with the PSP, and implement whatever the PSP recommends. On Token Replacement we can only confirm that your message was relayed - everything beyond that is between you and the PSP.
