# Concepts

> The ideas to know before you take the Ryvo API to production: errors, idempotency and rate limits.

Read these three pages before you take an integration to production:

* [Errors](/errors): stable error codes and how to react to each one.
* [Idempotency](/idempotency): how to avoid firing 2 calls if your system retries the same request.
* [Rate limits](/rate-limits): how many requests per minute you can make and how to react to the limit.
