Loading HTML fragment from external API via server side

stacktome

Hi, I would like to set up HTML fragment loading using the API on a page that's loaded on the server side. I couldn't find any documentation on how to do it; the only viable solution I see is uploading a template file and then loading it via load_template described here: https://developers.maropost.com/documentation/neto-designer-documentation/b-se-tag-library/function-tags/templating/load_template/

However, it's a bit cumbersome to reupload files via sFTP in 2026, so maybe there is another option, ideally via API or even better within page templates themselves. The ContentUpdate endpoint with Description1 doesn't fit this use case as it's limited to 5K chars only, which is way too small for content page updates.

Any suggestion is very welcome, thanks!

I don't really get what you're trying to achieve. Where is the HTML fragment coming from and what is in it? Why does it need to be stored in Neto? You'll have to give us a lot more detail on your project.

The SFTP is for accessing the template files Neto uses to render the ecommerce front-end. These are generally quite static, it's not an arbitrary file store. Hence there's no API for accessing the files.

Yes, the ContentUpdate API would probably work but if you're needing to store more than 5K of characters then it doesn't seem like the right solution anyway.

Neto sites pair well with external systems, it's not unusual for a site to load some of its content over AJAX from a third party server which is hosting some sort of custom app.
