Capture leads in Growform, close them in NationBuilder
If you are looking to integrate your forms with NationBuilder, Growform has the solution for you. When a new form submission is received, Growform’s NationBuilder integration allows you to perform a range of actions such as creating or updating a person or creating a logged contact. With Growform, you can easily capture and manage your data, helping you to streamline your workflow and improve your efficiency.
For a sales team, that means every lead lands in NationBuilder the moment it is submitted, with the answers from each step of the form attached, so reps can prioritize, assign and follow up without retyping anything. Multi-step forms typically collect more leads than a single long page, and conditional logic and hidden fields mean NationBuilder receives clean, well-qualified records with campaign data intact.
