What integration options are available?

Technology partners can integrate through PXP's REST API, native Kotlin SDK, local HTTP REST calls, or webhook-based event flows. The integration path depends on your platform architecture and whether you're building for in-store, online, or both.

Do my merchants need separate contracts with the different acquirers?

No. PXP manages acquiring relationships. Your merchants sign with PXP, and smart routing handles which acquirer processes their transactions based on performance, geography, and card type. Merchants don't need to manage acquirer relationships directly.

How long does integration typically take?

It varies depending on complexity and which products you're integrating. PXP's technical team supports the process from scoping through testing and certification. Sandbox access is available immediately.

What are the hardware options for in-store integration?

PXP uses Castles Android-based Saturn terminals. They're acquirer-agnostic, meaning the hardware doesn't need to change if routing changes. Contract terms run from 12 to 48 months, and asset finance options are available.

How is commission structured?

Revenue share is calculated on the transaction volume your merchants process. It's tracked automatically through Launchpad and paid for the lifetime of each customer relationship. PXP does not re-paper merchants or end commission after a set period.
