Please, how do I create a downloadable pdf file from information filled by a user?

Hello everyone

The APIs named in the old posts are now all paid (no free account available).

I am testing the FREE API from pdflayer.com directly from the web option found on the Dashboard page.

The API with my key works perfectly if I point to wikipedia, google or any other website.

But it fails if I point to MY websites, hosted on Wix, with 404 error.

Will it be latency or some blockage from WIX?
Has anyone successfully tested the pdflayer API with wix sites?

Regards
Juan Pablo
