# API Keys

The API key structure for Numeral's services follows a specific pattern that ensures both security and clarity. Keep production keys secure - a bad actor with your API key can learn sensitive information about your business.

You can create API keys in either a `test` or `production` mode. Keys will lead with `sk_test_...` or `sk_prod...`

`test` keys: This environment is used for development and testing purposes. Transactions recorded with test keys will not incur any charges or tax remittance.

`production`: Production keys handle live traffic. Numeral will file production `transactions` with the states as appropriate.

Create and manage developer keys in your [Numeral developer dashboard](https://dashboard.numeralhq.com/developers) under the `API Keys` tab.
