API Documentation (Excerpt)

Terms and Definitions

Throughout this document and the Trelio platform the following terms are used:

  • Payor. An entity (typically a corporation) which wishes to pay funds to one or more payees via a payout.
  • Payee. The recipient of funds paid out by a payor.
  • Payment. A single transfer of funds from a payor to a payee.
  • Payout. A batch of Payments, typically used by a payor to logically group payments (e.g., by business day). Technically there need be no relationship between the payments in a payout – a single payout can contain payments to multiple payees and/or multiple payments to a single payee.
  • Sandbox. An integration environment provided by Trelio Payments which offers a similar API experience to the production environment, but all funding and payment events are simulated, along with many other services such as OFAC sanctions list checking.


The Trelio Payments API allows a payor to perform a number of operations. The following is a list of the main capabilities in a natural order of execution:

  1. Authenticate with the Trelio platform
  2. Maintain a collection of payees
  3. Query the payor’s current balance of funds within the platform and perform additional funding
  4. Issue payments to payees
  5. Query the platform for a history of those payments

This document describes the main concepts and APIs required to get up and running with the Trelio Payments platform. It is not an exhaustive API reference. For that, please see the separate Trelio Payments API Reference.

API Considerations

The Trelio Payments API is REST based and uses the JSON format for requests and responses.

Most calls are secured using OAuth 2 security and require a valid authentication access token for successful operation. See the Authentication section for details.

Where a dynamic value is required in the examples below, the {token} format is used, suggesting that the caller needs to supply the appropriate value of the token in question (without including the { or } characters).

Where curl examples are given, the –d @filename.json approach is used, indicating that the request body should be placed into a file named filename.json in the current directory. Each of the curl examples in this document should be considered a single line on the command-line, regardless of how they appear in print.
