Use case
Integrate once. Stay provider-neutral.
Your integration talks to one API. Each merchant is routed to an approved provider, and new providers are added as adapters without changing your code.
No sales call required. Free developer sandbox.

What gets in the way
Switching providers usually means rewriting your integration
Different providers mean different webhooks and error codes
History and refunds get messy after a switch

Frequently asked questions
Which providers are available today?
One licensed provider is integrated today, pending our platform's own verification with that provider. Other providers are added only once integrations and partnerships are in place; we don't list providers that don't work yet.
Do you fail over between providers automatically?
Not today. Automatic failover depends on legal and technical permission from each provider and is on the roadmap.
