Would you like to include the invoice number from WPForms for any completed Authorize.Net payment? Authorize.Net will accept certain metadata that they have already mapped to their payment API.
In this tutorial, we’ll show you how to send a payment invoice number as metadata for the Authorize.Net payments.
Creating your Authorize.Net Form
To start, create a new payment form or edit an existing one to access the form builder. In the form builder, make sure to add the Authorize.Net field.
Then proceed to configure your form and payment settings. For more details, please see our tutorial on setting up and using the Authorize.Net addon.
Adding the Snippet to Send an Invoice Number
Once your form is set up to accept these payments, the next step is to add the custom snippet below to your site. If you need additional help, check our guide to learn how to add custom code snippets to WordPress sites.
In our example below, we added a Hidden Field (fields[20]) form field that contains the Smart Tag {unique_value} to generate an invoice number when the form is submitted.
In the first part of the snippet above, we’re grabbing the invoice number stored in the Hidden field. This step is essential to inform the API of what field we want to pass through as the invoice number. Please remember to update this field ID to match the field ID of your form.
The second part of the code is where we send an API request to Authorize.Net and set the invoice number to the value generated in the Hidden field.
Now, when Authorize.Net payments are sent through WPForms, they will include the invoice number generated in WPForms.
