An application programming interface (API) key is a unique identifier used to authenticate a user, developer, or calling program to an API. You can find here more information about how to get your key.
You can revoke and re-issue API keys at any time.
It is recommended to
- use the API key in environments where the code is exposed, e.g. on websites or mobile applications. You can use the provided "secret" in backend applications where the code is secured
- re-issue the API keys once in a while, ideally every month.
