  title: InfluxDB API Service (V1 compatible endpoints)
  version: 0.1.0
  description: |
    The InfluxDB 1.x compatibility `/write` and `/query` endpoints work with
    InfluxDB 1.x client libraries and third-party integrations like Grafana
    and others.


    If you want to use the latest InfluxDB `/api/v2` API instead,
    see the [InfluxDB v2 API documentation](https://docs.influxdata.com/influxdb/cloud/api/).

        In your API requests, send an `Authorization` header.
        For the header value, provide the word `Token` followed by a space and an InfluxDB API token.
        The word `Token` is case-sensitive.
