Flywire

Flywire Payment Request API

REST API for creating, retrieving, updating and removing payer-facing payment requests for a company, including instalment schedules. Requests are authenticated with an HMAC-SHA256 digest of the request body sent in the X-Flywire-Digest header rather than a bearer token, and the surface has its own invoice/payment-request webhook lifecycle.
