Public API Key

API keys are meant for use in the client. They can only be used for POST requests and are only viable when made with a valid internalId. Be sure to keep your internalIds secure.

Private API Key

❗️

Only use your private key in your backend.

All get requests that return data must be made with a private key. Only use in your backend.

Sandbox Key

Since the sandbox key can only be used with test data, the same key can be used for public and private API calls.
