**Your software**
My Mautic version is: 4.4.10
My PHP version is: 7.4.33
My Database type and version is: mysql
**Your problem**
I want to create a landing page via the API while providing custom HTML.
- There seems to be no documentation of this in the docs, however I suspect this must exist
- Tried passing “customHtml” to the pages create and edit endpoint (since that’s how the mail endpoints are working)
- Tried passing “newContent” to the pages create and edit endpoint (I saw that parameter being used when trying to reverse engineer how the frontend is doing it)
- Tried posting to /s/pages/edit/ with an URL encoded page[customHtml] parameter (because that seems to be what the UI is doing if I’m interpreting this correctly)
Is there something available I can use that is simply undocumented?
