title: InfluxDB Cloud v1 compatibility API documentation
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](/influxdb/cloud/api/).

  This documentation is generated from the
  [InfluxDB OpenAPI specification](https://raw.githubusercontent.com/influxdata/openapi/master/contracts/swaggerV1Compat.yml).
