# Environments

> Understand how sandbox and production environments work in Moflay so you can test safely and go live cleanly.

Moflay separates testing from live traffic with two environments: `sandbox` and `production`.

## Sandbox

Use sandbox while you are building and validating your integration.

* Safe for testing
* Separate API keys
* Separate data from production
* Shared or custom sandbox credentials depending on your setup

Sandbox API keys start with `mof_test_`.

## Production

Use production only when you are ready to accept real payments.

* Requires your own live Daraja credentials
* Uses separate API keys and transaction data
* Sends real payment requests through your configured till or paybill

Production API keys start with `mof_live_`.

## Why the separation matters

Environment isolation helps you:

* Avoid mixing test and live traffic
* Keep credential mistakes from affecting real customers
* Validate your webhook and transaction flows before launch

## Recommended workflow

1. Build in sandbox.
2. Create and test your API integration.
3. Configure production Daraja credentials.
4. Generate production API keys.
5. Switch your deployment to production only after verification.
