## Authentication

- `Authorization` header (required) — This key is used for all apis with the exception of ingest. You can obtain it following [these instructions](https://docs.mezmo.com/docs/ingestion-key) and placing the key in the header of your call in the format of `Authorization: Token {accesstoken}` For example: ``` curl -H 'Authorization: Token <ACCESS TOKEN>' ```
- `servicekey` header (required) — (Deprecated) This key is used for v1 and v2 apis with the exception of ingest. Service keys can be used by placing your service key in the `Authorization` header of your api call. *NOTE* Usage of the service key auth mechanism has been deprecated in favor of IAM Access Tokens. Service keys can no longer be created, but can still be used for v1 and v2 apis while the transition takes place
