  title: Unit Accounts Webhooks API
  description: Unit is a Banking-as-a-Service (BaaS) platform. This document is an API Evangelist consolidation of Unit's public REST surface, organized into logical groupings (Applications, Customers, Accounts, Cards, Authorizations, Payments, Counterparties, Checks, Transactions, Statements, Tax Forms, Events, Webhooks, Risk/Fraud, Credit/Repayments, Fees, Rewards, and API Tokens). All paths, methods, and the request/ response envelope below were confirmed against Unit's officially published OpenAPI 3.0.2 specification at github.com/unit-finance/openapi-unit-sdk (openapi.json, version 0.4.0); request/response bodies here are condensed and re-typed for readability rather than reproduced schema-for-schema. Unit's API follows the JSON:API specification - every request and response uses the `application/vnd.api+json` media type, wraps the primary resource in a top-level `data` object with `type`/`id`/`attributes`/`relationships`, and authenticates with a Bearer JWT obtained as an org API token or a customer API token.
