JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
When embedding the form you only need to make sure there are no conflicts between the scripts in the website and the scripts in the form, internet connection is also required for the form to properly reach our servers and complete the submission. The submission process is handled on our end and there nothing that needs to be set up at the moment of embedding a form.
What I would suggest you to avoid inconveniences when embedding the form is to use the iFrame code, here's the guide: Getting-the-form-iFrame-code
If you need to handle the data and process it on your end too then you could also get it using the POST method, here's a guide that will provide you the steps to achieve it: Send-Submission-Data-via-POST-Method-Using-PHP-and-the-Thank-You-Settings
If you have any question, please let us know.
