How to create ticket purchases form?

Necesito crear un formulario para crear reservas de entradas para un evento, que se genere automáticamente un código, que se envíe al mail y luego poder canjear por la entrada.

For ticket reservation form you can use our Ticket purchases widget:

Regarding the automatic emails, please refer to our Notification guide where you can find all relevant information about setting up the mailing of submitted data.

Now regarding the code, how would you like that code to be used after it is generated, could you please shed some light on that workflow so we can give you the best possible solution.

We'll wait for your response.

Thank you!

El código que se genere y se envíe al mail, es con el cual podrán cambiar la entrada en el acceso el día del evento.

Or, instead of the Unique ID, you can use the random value generator widget: https://widgets.jotform.com/widget/random_value_generator.

Now, if you want to incorporate the code as a coupon in the payment field, you have to set it up in the coupon settings of the payment integration:

Note that this is a manual process. After each submission, you have to add the generated unique ID/value as a coupon. Otherwise, they cannot redeem their respective discount(s).
