Travel Rule Protocol (TRP) API (3.2.1)

Public TRP API for VASP-to-VASP Travel Rule data exchange.

Working with the documentation

This section describes the public endpoints of the Travel Rule Protocol (TRP) Registry API. These endpoints allow third-party systems and Virtual Asset Service Providers (VASPs) to discover, identify and register participants in the TRP network.

The API follows REST conventions and returns responses in JSON format. All requests should be made over HTTPS.

Introduction: How the TRP Public API Works

The TRP API enables VASPs to:

Authenticate using API keys
Generate unique Travel Addresses for beneficiaries
Initiate Travel Rule transfers
Exchange originator and beneficiary data securely
Receive callback notifications from TRP during the verification process

TRP follows global compliance standards (FATF, IVMS101) and ensures secure, encrypted communication between VASPs.

Every integration follows one simple flow:

Request JWT token → authenticate your VASP
Generate Travel Address → unique identifier for the beneficiary VASP
Initiate Transfer → send IVMS101-compliant data
Receive callback → TRP sends status updates to your backend

Authentication Overview

Before calling any protected endpoint, your system must generate a JWT access token using your API Key. This ensures:

Secure API access
Verified VASP identity
Ability to track API usage
Authorization for initiating Travel Rule transfers

The access token is short-lived (TTL ≈ 1 hour) for security reasons. Pass it as Authorization: Bearer <jwt> on every protected endpoint.

Conventions

All bodies are application/json unless explicitly stated.
Successful responses are wrapped in { "status": true, "data": ... }.
Errors are wrapped in { "status": false, "errors": [{ "code", "message" }] }.
Timestamps use ISO-8601 in UTC.
Country codes follow ISO-3166-1 alpha-2.

Identity

Public identity endpoints. These return non-sensitive VASP metadata (legal name, LEI, x509 public key) and server health. They do not require authentication.

Operations

Auth

Authentication endpoints. Use your API Key (issued in the TRP dashboard) to obtain a short-lived JWT that authorises every protected call.

Operations

Address

Travel Address endpoints. A Travel Address is an opaque, URL-safe encoding of a beneficiary VASP route. It is generated by the beneficiary VASP and shared with the originator VASP so that IVMS101 data can be routed back.

Operations

Transfer

High-level Travel Rule transfer operations from the originator VASP perspective. Transfers can flow two ways depending on what was provided at initiation:

OPEN_VASP — beneficiary VASP is reachable via Travel Address.
EMAIL — beneficiary VASP is unknown; we send an email so the recipient can self-attest.

Operations

Initiate Travel Rule transfer

Request

Main Travel Rule operation. Submits originator and beneficiary applicants, asset, amount, and optional routing info (travelAddress or email).

Flow selection

Provided fields	Resulting `flow`
`travelAddress`	`OPEN_VASP`
only `email` (top-level or `beneficiary.email`)	`EMAIL`

What TRP does next

Persists the transfer with APPROVED originator status.
Resolves originator and beneficiary VASP IDs.
In OPEN_VASP flow, queues an INQUIRY callback to the beneficiary VASP endpoint (extracted from the Travel Address).
In EMAIL flow, sends a confirmation email and flips isEmailDelivered once Mailjet acks.
