Build cross-border payments with the Onboard API

The Onboard Business API is served over HTTPS. Pick the base URL for the environment you’re targeting and append the endpoint path from the API reference.

Environment	Base URL
Production	`https://business-api.onboard.xyz`
Production (alternate)	`https://api-3p.onboard.xyz`
Sandbox	`https://external.dev.onboardpay.co`

For example, Get API Info (GET /exchange/api/info) in production is:

GET https://business-api.onboard.xyz/exchange/api/info

Production

https://business-api.onboard.xyz is the primary production base URL — use it for new integrations. https://api-3p.onboard.xyz is an interchangeable alias that resolves to the same production gateway, so integrations already pointed at it keep working. Pick a single host per integration and use it consistently.

Sandbox

Build and test your integration against sandbox before going live. No real funds move on this environment.

Every request is authenticated regardless of environment — the same API key and HMAC signature are required in sandbox and production. See Authentication.
