Sandbox
https://sandboxapi.me-cash.comSimulated money movement, ideal for integration testing and demos.
Production
https://api.me-cash.comProcesses real transactions once your business is approved.
Sandbox environment
The sandbox mirrors live behavior while keeping funds virtual—perfect for prototyping and QA.- Authentication: Use your sandbox API keys from the dashboard.
- Webhooks & events: All endpoints fire test payloads so you can validate handlers.
- Data reset: Wallet balances and transactions are synthetic and may reset periodically.
- Create your business account.
- Follow the Quickstart to generate sandbox keys.
- Whitelist the IPs that will call the API via /ip-whitelisting.
Production environment
Production is where your customers experience real payouts, collections, and settlements.- Base URL:
https://api.me-cash.com. - Traffic: Real money movement with full compliance monitoring.
- Rate limits: Higher throughput tiers are available on request—contact support with your projected volumes.
- API keys: Issued separately from sandbox; never reuse test keys in production.
- Complete KYB.
- Finish smoke testing in sandbox, including webhook verification.
- Request production keys from the dashboard or by emailing [email protected].
- Whitelist the production IP addresses that will originate live traffic.
Keep production credentials in a secure secrets manager. Rotate keys regularly and remove unused IP addresses to minimize attack surface.
