# Credits

WPayme is a derivative work. It is built on two GPL-licensed projects, and large
parts of this plugin are their code with the namespaces, identifiers and branding
changed. Their copyright notices are retained in the file headers, as the GPL
requires; this file records the provenance in one place.

Provides the regional gateways and the wider set of plugin integrations:

| Ours | Upstream |

`packages/wpayme/gateways/PayPalRest` is Knit Pay's PayPal Orders v2 gateway,
