API Sandbox - Fast Track to MTS Integration

✅ Check how easy it is to integrate with the MTS API using the Transaction 3.0 Sandbox.

✅ Polish your integration against the Sandbox before you continue integrating with MTS in the integration environment — same Java SDK, same WebSocket flow, same transaction structure.

✅ Start in minutes with OAuth + WebSocket connectivity, then iterate safely until your placement, cancellation, and settlement paths behave exactly as you expect in production.

✅ Build requests with the official MBS SDK and receive responses, then quickly focus on ticket content and error handling.

✅ Explore 30+ documented scenarios—promo stakes, alt odds, reoffer flows, liability and market rejects with Java examples, wire JSON, and expected responses.
