Orca

Orca is a payment orchestration platform built for merchants who outgrew a single provider. One integration reaches every acquirer, gateway and alternative method already in this directory, and the routing between them is yours to set: by market, by method, by card range, by amount, by issuer, or by whatever a provider did to you last Tuesday.

Where it earns its place is the awkward part of payments. A cascade that retries a declined card at a second acquirer without asking the customer again. Per-currency and per-branch velocity limits. Card-on-file through a PCI vault, so tokens survive changing provider. A/B routing you can read the numbers on, and a decline taxonomy that says which failures are worth retrying and which are the issuer telling you to stop.

It is used by platforms that carry other people's merchants — igaming operators, forex brokers, marketplaces — where one provider is never enough and switching has to be possible without a rebuild. Hosted fields and a hosted cashier are available where a merchant would rather not touch card data at all, and an A2A rail covers the markets where cards are the expensive way to get paid.
