# Build and test Airwallex integrations

By Steven Van · 2026-09-25

Replit Agent can now build and test Airwallex payment integrations through MCP, using Airwallex's sandbox instead of a live account.

[Replit](<https://creatorstoolbox.com/tools/replit>) Agent can now connect to Airwallex through MCP, giving it access to Airwallex's documentation and sandbox tools for building payment integrations.

Testing runs against Airwallex's sandbox, so it doesn't touch a live production account. To set it up, find "Airwallex Developer" in Replit's MCP directory, then follow the [Connect via MCP](<https://docs.replit.com/build/connect-via-mcp>) guide and Airwallex's own setup guide.
