Sandbox Environment

Full Testing Before Launch

Reduce Manual Reconciliation Costs

The sandbox environment simulates real transaction flows with full API call testing. All webhook events, signature verification and error codes are identical to production, helping integrators complete end-to-end validation before launch and significantly reduce post-launch reconciliation and troubleshooting costs.

Integration Flow

From Registration to Production

Register and Get API Key

Create a merchant account in the console. API Key is automatically issued after identity verification.

Test in Sandbox Environment

Use sandbox keys to complete end-to-end integration testing in an isolated environment without real funds.

Submit Compliance Materials for Review

Submit KYC/KYB materials and business scenario descriptions for review by the compliance team.

Switch to Production

After passing review, switch to production keys, go live on the planned schedule and enable real-time monitoring.
