# Learn to use APIs for your workloads

Choose the InfluxDB Clustered API and tools that best fit your workload:

### [InfluxDB v2 API compatibility](/influxdb3/clustered/guides/api-compatibility/v2/)

Use the InfluxDB v2 API for new write workloads and existing v2 write workloads. InfluxDB Clustered is compatible with the InfluxDB v2 API `/api/v2/write` endpoint and existing InfluxDB 2.x tools and code.

### [InfluxDB v1 API compatibility](/influxdb3/clustered/guides/api-compatibility/v1/)

Use InfluxDB v1 API authentication, endpoints, and tools when bringing existing 1.x workloads to InfluxDB Clustered.
