The flow editor

Visually build logic and automations for your forms

Easily configure custom server-side logic, integrate any service with an API and automate tasks in any stage of the form.


Flow editor features

Run flows in any step of the form

Execute custom server-side logic flows in any step of the form. Validate data, jump between steps, integrate any service with an API and trigger different actions and automations based on form inputs.

Intuitive data autocomplete

Get data from your form fields and from previous flow actions using the autocomplete data menu.

Simply configure action fields by selecting the variables you need from previous executions of the flow.

Advanced expressions and calculations

Use math operators to do calculations and build logic based on its results. You can even use advanced functions as round, generate random numbers, transform between data types or use nullish operator "??" to build your logic.

Store state variables

Store custom variables and use them both in the form and the next flows linked to it.

Transform data, pass it through the different flow actions, use it to prefill form inputs or to modify form fields configuration.

Generate OTPs and filter emails

Generate temporal codes with native actions and send them to an email or a phone to verify that your user has access to it. In addition, you can block free emails and configure which domains are allowed.

Debugging mode

Check if everything is working properly by debugging your flows, action by action. Easily find and solve bugs by inspecting the inputs, outputs and errors of the actions of your flows after any execution.
