How to Set Custom HTTP Headers for Collections and API in Payload CMS and Remove X-Powered-By Header

[karltdev]

I'm working with Payload CMS and need to set custom HTTP headers for responses from collections and API endpoints. Additionally, I want to remove the X-Powered-By header for security reasons. From my research, many solutions suggest using Express middleware in payload.config.js, but it seems Express support might have been removed or changed in recent versions.

What’s the best way to achieve this in the latest version of Payload CMS? Any code examples or references to documentation would be greatly appreciated. Thanks!
