    Authorize.NET is asking for an invoice number for transaction to complete.

    How do you put an auto generating invoice numbering field in form?

    Hi Leon,

    Thanks for posting your inquiry here. You may want to try one of our new features called Unique IDs. This field allows you to assign a unique ID for each submission, and this number automatically increments for every successful submission. You can use this as your invoice number in your forms.

    To learn more about Unique IDs field, please visit this tutorial: .

    I am glad to inform you that it is now possible to send an invoice number to Authorize.Net for your form transactions using either a hidden box or a unique ID field.

    To do this:

    1.  Add a Hidden Box or Unique ID field to your form
    2.  Select your payment field, right click on it, then choose Show Properties
    3.  Choose a field whose value will be used as the invoice number for purchases made using your form
    4.  Save your form afterwards

    Please let us know if you need further assistance, or if you have any feedback regarding this newly implemented feature.

    Best regards
