**Kibana version** : 8.4.1
**Elasticsearch version** : 8.4.1
**APM Server version** : 8.4.1
**APM Agent language and version** : nodejs, elastic-apm-extension-ver-1-1-0-x86\_64, elastic-apm-node-ver-3-38-0
**Browser version** : /
**Original install method (e.g. download page, yum, deb, from source, etc.) and version**: lambda layers
**Fresh install or upgraded from other version?**
**Is there anything special in your setup?**
**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**: There is an AWS Api-gateway with API key placed between lambda and APM server. Is there any ways to add custom header (E.G. api-gateway key) on APM agent? So that every APM agent's request towards APM server will contain api-gateway key in the header.
**Errors in browser console (if relevant)**: 403 return code from api-gateway
**Provide logs and/or server output (if relevant)**:

Hello @alex_123123,
In Elastic's APM lambda architecture, the APM agent (Node.js in this case) talks to the local APM extension, which then talks to the APM server.
If I understand your setup correctly, you'd need a way to tell the APM extension to add `x-api-key: $configuredValue` to all requests to APM server. The Node.js APM agent does not expose a configuration option to set headers for requests to APM server. @lahsivjar Do you know if the Lambda Extension has any such configuration? My guess is that it does not.
@alex_123123 If that is the case, then the next best step is to add a feature request to the Elastic APM Lambda extension repo: [Issues · elastic/apm-aws-lambda · GitHub](https://github.com/elastic/apm-aws-lambda/issues)

Thanks for the answer. You are correct, there is no such configuration in the lambda extension at the moment.
