ViaBlocks API Outbound is a secure, server-to-server REST API that enables regulated partners to create, manage, and track outbound cross-border money transfers from the United States to international destinations through the Viamericas network.

The API supports the full outbound transaction lifecycle, including U.S.-based sender onboarding, international beneficiary onboarding, transaction creation, funding initiation, foreign exchange (FX) handling, payout execution, and end-to-end status monitoring.

Partners interact with the platform through two primary endpoints: POST /transaction/create, used to submit sender, beneficiary, and transfer details to initiate an outbound transaction, and POST /transaction/status, used to retrieve the most recent processing status and lifecycle updates for an existing transaction.

This API is designed for licensed and compliant U.S. partners and abstracts regulatory, compliance, routing, and payout complexities, allowing integrators to focus on building scalable international money transfer experiences.

Transaction

This section provides the Transaction endpoints required to manage and operate the full lifecycle of resources within the ViaBlocks platform.
These endpoints are designed for secure, auditable, and scalable server-to-server integrations, and support core business operations and compliance workflows.

Operations

/transaction/create

Request

Purpose

Creates a new outbound cross-border money transfer and registers it in the ViaBlocks platform.

This request defines the sender, beneficiary, transaction details (amounts, currencies, destination), and the selected funding method.

When to use

Use this endpoint to initiate a new transaction when you are ready to submit:

Sender onboarding details (KYC/AML fields)
Beneficiary details and payout configuration
Origination and delivery amounts/currencies
Funding configuration (cash or remote payment)

What happens next

Next steps depend on the funding method:

Cash funding: Transaction may proceed directly into processing (partner-dependent).
Remote payment funding: Transaction is created in a pending funding state. The sender must complete payment remotely and the transaction will not proceed until funding and risk/compliance review are completed.

Authentication

Requires x-client-id and x-secret-key headers.

Notes

Request validation is enforced for formats, allowed values, corridor rules, and compliance requirements.
For the remote payment flow, refer to: ../guides/remotepayment.md

Common errors

400 Validation errors (missing/invalid fields)
401 Invalid credentials
404 Sender/beneficiary linkage issues (when applicable)

Catalogs

This section provides the **Catalogs** endpoints required to retrieve reference and configuration data necessary to construct and validate outbound money transfer transactions within the ViaBlocks platform.
Catalog endpoints expose corridor-specific operational data including supported countries, currencies, delivery methods, payout networks, payout locations, identification document types, industries, remittance purposes, and source-of-funds classifications.
These endpoints are read-only and must be consumed prior to transaction creation to ensure:

Compliance with country-specific regulatory requirements
Correct validation of amounts, currencies, and payout configurations
Dynamic population of UI selection fields
Alignment with real-time operational rules and payout network constraints

Partners should not hardcode catalog values and should instead retrieve them programmatically to maintain synchronization with configuration updates, compliance changes, and corridor availability.
