title: Telemetry SDKs: Report custom telemetry data
source: https://docs.newrelic.com/docs/data-apis/ingest-apis/telemetry-sdks-report-custom-telemetry-data
---

Our Telemetry SDKs are an open source set of API client libraries that send data to the New Relic platform. Under the hood, these SDKs rely on our primary data ingest APIs: the Metric API, Trace API, Log API, and Event API.

If our [pre-built solutions](https://newrelic.com/instant-observability) don't meet your needs, our Telemetry SDKs are one way to create a custom telemetry solution (see other [solutions for reporting custom data](https://docs.newrelic.com/docs/data-apis/custom-data/intro-custom-data)).

## Requirements and compatibility [#requirements]

The Telemetry SDKs use our Metric API, Event API, Log API, and Trace API, which all require a license key, so you'll need a license key for the account you wish to send data to.

> #### 💡 TIP
>
> New Relic has contributed the Telemetry SDK to the open source community under an Apache 2.0 license.

## Available libraries [#client-libraries]

The Telemetry SDKs are open source software on GitHub. Use the language-specific GitHub links below to get library details, coding examples, and procedures for how to use the SDKs. We currently support the following libraries, with more to be created in the future:
