Frequently asked questions
Clearent scores C on Supergood's API Report Card. Clearent, now Xplor Pay, documents Transaction, Boarding, Reporting, Dispute, and Recurring Payments REST APIs with sandbox and production gateways. Keys are partner-gated: you onboard as an ISV, and merchants cannot call the API directly. Two overlapping doc sites split the reference.
Clearent has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Clearent, rebranded as Xplor Pay following the 2021 merger of Clearent and Transaction Services Group (TSG) into Xplor Technologies, is a full-stack payment processor that combines direct merchant acquiring with an embedded-payments / PayFac-as-a-Service offering for vertical SaaS platforms.
Financial Services (Payment Processing / Embedded Payments), Two distinct customer bases: (1) direct SMB and mid-market merchants accepting card-present and card-not-present payments, and (2) vertical SaaS / ISV partners who embed Clearent's payments rails, boarding, reporting, and dispute APIs into their own software (fitness, education, field services, health & wellness, childcare). Direct merchants use Clearent for in-store and online card acceptance, encrypted card readers, virtual terminals, hosted payment pages, recurring billing, ACH, gift cards / loyalty, smart invoicing, cash-discounting programs, and chargeback / dispute management, all visible in the Clearent Compass merchant portal.

Yes, Clearent holds the full payments substrate for tens of thousands of SMB and mid-market merchants: every authorization, settlement, refund, chargeback, ACH transaction, tokenized card-on-file, customer/recurring billing schedule, deposit ledger, merchant statement, KYC/boarding application, and risk/underwriting record.

API access requires becoming a formal ISV/partner, small merchants and end-customers cannot use the API directly. Two parallel doc sites (developer.clearent.com and docs.xplorpay.com) with overlapping but not identical coverage create integration confusion. Full sourced list under Sources below.
Common alternatives include Stripe Connect, Adyen for Platforms, Global Payments / Heartland, Fiserv (Clover / CardConnect), Worldpay (FIS), Payrix (a Worldpay company). Graded alternatives appear under "More from the report card" below.
Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Yes, via a managed API layer. Supergood builds REST APIs and MCP servers for authenticated enterprise web apps, so AI agents and internal tools can read and write data programmatically. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
Not that we could find. As of August 2026 there is no official Clearent MCP server in any public registry, and no maintained community server we're aware of. We re-verify this periodically — report an inaccuracy below if we missed one.
Not natively. Clearent doesn't publish an MCP server, so MCP clients like Claude, Cursor, and Codex have nothing to connect to out of the box. If that changes, this page will reflect it.
