Hi @SIMON TUBEY !
We have a Typeform integration built by Typeform themselves in our Marketplace, check it out here.
Pipedrive free trial accounts work just the same as paid accounts, so there should be no restrictions to using integrations with other tools from our end. I recommend you take a look at the setup instructions in the link above and if you still have questions or any issues reach out to Typeform's support team, also listed there. 🚀
