ConnexPay
ConnexPay is a Milwaukee-founded B2B payments platform that combines merchant acquiring and card issuing in one integration, so a company's incoming customer payments directly fund its outgoing supplier payments with no float in between. An inbound Sale (PayIn) returns an Incoming Transaction Code that funds the virtual cards, ACH credits, push-to-card payouts, checks and international bank-to-bank transfers issued against it (PayOuts). The platform is used heavily in leisure and business travel, advertising and media buying, insurance claims, and embedded-payments software, and is delivered through ten REST APIs — Sales, Purchases, Push to Card, Payment Valet payment instructions, Checkout Session, Merchant Payor, Stop Payment, Chargebacks (CMS), and two Reporting surfaces — plus a browser payments SDK, a Hosted Payment Page, the Bridge operator console, and a 51-event webhook surface called CXP Eventing. ConnexPay is a registered ISO/MSP of The Central Trust Bank and MVB Bank.
ConnexPay publishes 39 API contracts indexed on the APIs.io network, including Accounting API, Addendum API, Authenticate API, and 36 more. Tagged areas include Payments, Virtual Cards, Card Issuing, Merchant Acquiring, and Payouts.
The ConnexPay catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
ConnexPay’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, changelog, and 29 more developer resources.

Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
