All other functions: the HTTP Request node

Every 1001fx function is a plain HTTPS endpoint, so you can call those without a ready-made node as well.

Add the HTTP Request node. Method: POST.
URL: the endpoint from the function page, for example https://api.1001fx.com/files/html2pdf.
Authentication: Generic credential type, Header Auth, with the name X-API-KEY and your API key as value.
Body: JSON for JSON functions, or Form-Data with an n8n binary file for file uploads. Set the response format to File when the function returns a file.

Calls that take longer than your workflow waits can run in the background: see long-running functions and webhooks.
