# Ingest APIs

Before you index your data, OpenSearch's ingest APIs help transform your data by creating and managing ingest pipelines. Pipelines consist of **processors**, customizable tasks that run in the order they appear in the request body. The transformed data appears in your index after each of the processor completes.

Ingest pipelines in OpenSearch can only be managed using ingest API operations. When using ingest in production environments, your cluster should contain at least one node with the node roles permission set to `ingest`. For more information on setting up node roles within a cluster, see [Cluster Formation]({{site.url}}{{site.baseurl}}/opensearch/cluster/).

Introduce Nodes APIs In this commit we are introducing a new section in REST API Reference for Nodes APIs. We are adding documentation for "Nodes hot threads" and "Nodes info". Because Nodes APIs share common request parameters we also add more detailed section into parent index page (notice that the nodes-filter parameter was moved from "Cluster stats" page and was improved, and relevant links were updated). There are more Nodes APIs that still need to be documented, this is just a good start. We updated nav_order parameter for some pages as well.
