Do's And Don'ts
Every form input field you added to your form must have a name attribute with a unique name. Your input fields should look like this:
You should post your data through secure HyperText Transfer Protocol (HTTPS). If you post your data through HTTP, your data won’t be submitted to FabForm
If you are accepting files for your forms by using only HTML or JavaScript, you should add enctype=multipart/form-data” to your form tag.
If you want to get a response message as JSON, you must set HTTP Accept Header to application/json.
