# Connectors, clients & APIs

Apache Pinot connects to applications, BI tools, federated query engines, and stream or batch processing systems in different ways. This section is organized by user intent so you can start from what you are trying to build instead of from a legacy product bucket.

## Choose an integration path

{% content-ref url="connectors-clients-apis/client-libraries" %}
[client-libraries](https://docs.pinot.apache.org/build-with-pinot/connectors-clients-apis/client-libraries)
{% endcontent-ref %}

{% content-ref url="connectors-clients-apis/bi-tools" %}
[bi-tools](https://docs.pinot.apache.org/build-with-pinot/connectors-clients-apis/bi-tools)
{% endcontent-ref %}

{% content-ref url="connectors-clients-apis/query-engines" %}
[query-engines](https://docs.pinot.apache.org/build-with-pinot/connectors-clients-apis/query-engines)
{% endcontent-ref %}

{% content-ref url="connectors-clients-apis/processing-connectors" %}
[processing-connectors](https://docs.pinot.apache.org/build-with-pinot/connectors-clients-apis/processing-connectors)
{% endcontent-ref %}

{% content-ref url="connectors-clients-apis/rest-grpc-apis" %}

{% endcontent-ref %}

## Build guidance vs API reference

This section explains when to use the REST or gRPC APIs and how they fit into application workflows. Detailed endpoint reference belongs in [Reference > API reference](https://docs.pinot.apache.org/reference/api-reference).

## What this page covered

This page grouped Pinot integrations by the job you need done: application clients, BI tooling, federated query engines, processing connectors, and direct API access.

## Next step

Open the page that matches your integration path, such as [Client libraries](https://docs.pinot.apache.org/build-with-pinot/connectors-clients-apis/client-libraries) or [REST / gRPC APIs](https://docs.pinot.apache.org/build-with-pinot/connectors-clients-apis/rest-grpc-apis).
