Flywire Invoicing API is one of 3 APIs that [Flywire](https://apis.io/providers/flywire/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Invoicing, Accounts Receivable, B2B Payments, and Credit Notes. The published artifact set on APIs.io includes API documentation, an API reference, authentication docs, and a changelog.

REST API for the Flywire Invoicing Platform — contacts, invoices, credit notes and invoice payments for a company, with search, count and export on each resource. Authorized with OAuth 2.0 client credentials and enforced on two axes: the token must carry the scope for the resource and operation, and it must be scoped to the company named in the URL. Documented on Flywire's Solutions documentation estate, separately from the Payments API.
