API Variables: Fetch answers dynamically from external sources

Use API lookups to enrich your form with dynamic data like product prices, store locations, or user account information, all based on responder inputs. Whether you need a simple lookup or a complex result processing, API variables empower you to provide a personalized and responsive experience.

Real-time data integration

Fetch up-to-date information directly from your server or a third-party API. Whether it’s looking up the latest prices, nearby locations, or account details, API variables ensure your forms always have accurate, dynamic data.

Customizable API calls

Easily customize your API calls using variables collected within the form. Templating URLs allows you to pass user inputs—like a zip code or email—directly to the API, ensuring personalized responses for each responder.

Seamless API response handling

Process complex API responses with built-in JSON accessors or custom mapping functions within the form builder. Extract multiple values from a single response and use them throughout your form, reducing the need for multiple API calls.

Error handling & loading states

If an API request fails or is slow, Formsort allows you to handle errors gracefully with custom error messages, or load alternate content while awaiting the response. Keep your form flow smooth, even when external data is involved.
