Customer self-insert public page

Guys, I'm looking for some way to create a simple form (regarding customer entry fields) to attach it in my website landing page (using iframe for instance), allowing my prospects to insert their data into this form and turn them leads straight into my Akaunting ERP database.
Anyone have any idea? It seems Akaunting just allow me to read data but not to write it without change core modules.

Hi Renato.

You need to make the integration with the API.

calling contact endpoint with a POST verb.
