Tithe.ly Payments & Tokenization API

  title: Tithe.ly API
  description: >-
    The Tithe.ly API lets churches and approved partners integrate with the
    Tithe.ly giving and church-technology platform. Access is gated: it is
    granted by request to organizations that use (or are moving to) Tithe.ly,
    and approved requesters receive public and private API keys by email. Two
    documented generations are modeled here. The V1 payments API handles
    PCI-safe tokenization (via the hosted Tithely.js library) and charging of
    tokenized cards and bank accounts. The V2 REST API handles login,
    organizations, payment categories (giving funds), donation transactions,
    and templated mail. Endpoint paths and methods are drawn from Tithe.ly's
    public documentation; request and response schemas are modeled from the
    documented behavior because the full field-level schemas are only exposed to
    approved API-key holders in the private developer docs. Test traffic uses the
    tithelydev.com hosts; production uses tithe.ly.
