-Flux can be used to query InfluxDB through InfluxDB's `/api/v2/query` endpoint.
+Query InfluxDB through the `/api/v2/query` endpoint.
 Queried data is returned in annotated CSV format.
 
 In your request, set the following:
 
+- `Authorization` header to `Token ` + your authentication token.
 - `accept` header to `application/csv`
 - `content-type` header to `application/vnd.flux`
 
 This allows you to POST the Flux query in plain text and receive the annotated CSV response.
