# Sandbox vs production environments
## Base URLs, rate limits and rules for the Remitian sandbox and production environments, and what stays separate between them.
### What it is
The Remitian Public API has two environments. Sandbox is for building and testing with synthetic data. Production is for live firms, real taxpayers and real tax payments.
### When you need it
- Use **sandbox** for initial development, testing changes, debugging and training.
- Use **production** once your integration is fully tested and ready to serve real users.
### How it works
| | Sandbox | Production |
| --- | --- | --- |
| Base URL | `https://public-api.sandbox.remitian.com` | `https://public-api.remitian.com` |
| Rate limit | 200 requests per 10 minutes | 1,000 requests per minute |
| Data | Synthetic data only | Real data |
| Tax payments | Not actually processed | Processed and submitted to tax authorities |
| Tax form import | Simulated data | Real extraction |
| Data persistence | Reset periodically, without notice | Persistent |
Firms, taxpayers, tax payment scheduling, webhooks, TIN filtering and SFTP file delivery are available in both.
A typical rollout:
1. Build and test in sandbox.
2. Validate every flow with test data, including how you handle rate limiting.
3. Set up separate production credentials and configuration.
4. Switch the base URL and go live, then monitor your usage against the limits.
### Common questions
### Can I use real customer data in sandbox?
No. Use only fictitious names, addresses, TINs and bank details. Never use real SSNs, EINs or bank account numbers in sandbox.
### My sandbox data disappeared. What happened?
Sandbox is reset periodically for security and maintenance. Do not depend on sandbox data persisting, and keep any test data you need in your own systems.
### Can I use the same credentials in both environments?
No. Use separate credentials for each environment, and never use production credentials in development or testing.
### Why does my TIN filter return 400 in one environment?
Each environment has its own TIN encryption key. A TIN encrypted with the other environment's key returns `400 Bad Request`. Download the key from the Developer Portal of the environment you are calling.
### Why is the sandbox limit so much lower?
It is intentional. Testing against a stricter limit helps you build retry handling before you go live.
