Cardtonic Business API

The Cardtonic Business API is the account, credential and compliance layer of Cardtonic's developer program, and the only Cardtonic surface with a published machine-readable contract. It covers business-account signup and email verification, business login, password recovery and change, two-factor enrollment, Nigerian BVN and corporate KYC submission, file upload, and issuance and retrieval of the PRIV_-prefixed API key a merchant integration authenticates with. Cardtonic publishes it as OpenAPI 3.0.1 through an Apidog-hosted documentation site at docs.cardtonic.com; the gift-card catalog, purchase, sale and bulk-order operations advertised on the developer page are NOT part of it and have no published contract.

Where this information came from

This is an independent, third-party profile of Cardtonic Business API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
