+
+Custom HTTP headers can be added to a component's Elasticsearch and OpenSearch HTTP clients by creating a new Java plugin, and adding the plugin to your Camunda 8 Self-Managed installation. Using custom HTTP headers may be helpful for adding authentication, tracking, or debugging to your database requests.
+
+## Create the Java plugin
+
+### Add the dependency
+
+Add the following dependency to a new Java project:
+
+<Tabs groupId="dependency" defaultValue="maven" values={
+[
+{label: 'Maven', value: 'maven' },
+{label: 'Gradle', value: 'gradle' }
+]
+}>
+
+<TabItem value='maven'>
+
+```xml
+<dependency>
+  <groupId>io.camunda</groupId>
+  <artifactId>camunda-search-plugins</artifactId>
+  <version>${version.camunda-search-plugins}</version>
+</dependency>
+```
+
+</TabItem>
+
+<TabItem value='gradle'>
+
+```yml
+implementation "io.camunda:camunda-search-plugins:${version.camunda-search-plugins}"
+```
+
+</TabItem>
+</Tabs>
+
+### Write your custom header
+
+Once the dependency is added to your project, write your plugin by implementing the `DatabaseCustomHeaderSupplier` interface (provided by the
+`camunda-search-plugins` package).
+
+The following example implements the `DatabaseCustomHeaderSupplier` interface, and uses it to return a custom authentication token and UUID:
+
+```java
+package com.myplugin;
+
+import io.camunda.plugin.search.header.CustomHeader;
+import io.camunda.plugin.search.header.DatabaseCustomHeaderSupplier;
+import java.util.UUID;
+
+public class MyCustomHeaderPlugin implements DatabaseCustomHeaderSupplier {
+
+  public static final String CUSTOM_TOKEN_PLUGIN = "X-Custom-Auth-Token";
+
+  @Override
+  public CustomHeader getElasticsearchCustomHeader() {
+    return new CustomHeader(CUSTOM_TOKEN_PLUGIN, UUID.randomUUID().toString());
+  }
+
+}
+```
+
+### Build your project
+
+Build your project with all dependencies included, and copy the resulting JAR file somewhere it can be easily accessed. This JAR file will be required by your Camunda installation.
+
+## Add the plugin to your self-managed installation
+
+To use your new plugin, it must be added to your Camunda 8 Self-Managed installation.
+
+### Mount the plugin
+
+For each container, mount your plugin's JAR file inside the container's file system. For more information, see the
+[Docker](https://docs.docker.com/engine/storage/volumes/) or [Kubernetes](https://kubernetes.io/docs/concepts/storage/volumes/) documentation.
+
+### Configure components
+
+Include the plugin parameters in each component's `application.yaml`, or pass them to the component as environment variables. For more information, see how to [configure components using Helm charts](/self-managed/operational-guides/application-configs.md).
+
+The following examples add the new `my-plugin` JAR to the `application.yaml` for Zeebe, Operate, and Tasklist:

+## Troubleshooting
+
+### Exception: Unknown type of interceptor plugin or wrong class specified
+
+This exception means that the incorrect class was specified in the `CLASSNAME` property. There are several causes that
+might lead to this exception:
+
+1. The class with such name or package does not exist
+2. The class does not implement the required SDK interface
+3. The class is inner, `static`, or `final`
+
+To solve this, make sure:
+
+1. You use the latest Search Plugins SDK
+2. Your classes implement correct SDK interfaces
+3. The plugin class is `public` and not `final`
+
+### Exception: Failed to load interceptor plugin due to exception
+
+Usually related to incorrect JAR loading. Please make sure that the path to your plugin JAR file is correct, and
+the application has access to read it. Also check that the JAR is correct and contains the required dependencies. To check the
+content of the JAR file, you can use the following command: `jar xf <file-name>.jar`.
