How to Install and Use the Authorize.Net Addon with WPForms

Would you like to accept Authorize.Net payments through your website’s forms? With the Authorize.Net addon for WPForms, your users can make secure credit card payments without leaving your site. Plus, you can set up both one-time and recurring subscription payments.

In this tutorial, we’ll show you how to install and set up the Authorize.Net addon with WPForms.

Requirements: You will need an Elite license to access the Authorize.Net addon.

Also, Authorize.Net requires your site to have SSL (HTTPS) enabled on the page where you’re adding a live payment form, as this allows you to securely send credit card data. For setup details, please see WPBeginner’s guide to enabling SSL and HTTPS in WordPress.


Before you get started, be sure to install WPForms on your WordPress site. Then you can go ahead and install and activate the Authorize.Net addon as well.

Connecting Authorize.Net to Your WordPress Site

Once the Authorize.Net addon is active on your site, you’ll need to go to WPForms » Settings in the left menu of your WordPress site. From there, click on the Payments tab.

Open Payments tab of WPForms settings

If you’d like to adjust the currency for your payment form, go ahead and select the option you need from the Currency dropdown before proceeding.

Next, scroll to the section labeled Authorize.Net. Here, you’ll need to fill out an API Login ID and Transaction Key to connect your site to your Authorize.Net account.

For these settings, you’ll need to get some details from your Authorize.Net account.

Note: These credentials are different for live and test transactions. For this tutorial, we’ll focus specifically on live transactions. If you’re trying to test your connection, please see our tutorial on how to test Authorize.Net payments.

Signing In to Authorize.Net

When you’re ready to sign in to your Authorize.Net account, be sure to do so in a new browser tab or window so you can easily switch back and forth between it and your WPForms settings.

If you don’t have an account with Authorize.Net yet, go ahead and create one now.

When you log in to your Authorize.Net account, you should see an overlay showing whether your account is in Test or Live mode. Be sure this option is set to Live.

Once you’re logged in and have confirmed that your account is in Live mode, you’ll be able to get the keys you need to connect Authorize.Net to WPForms. In the left sidebar of your Authorize.Net account, click on Settings.

Accessing Authorize.Net account settings

From the Settings page, you’ll then need to click on the option labeled API Credentials & Keys

On this page, you’ll need to copy the value next to API Login ID.

Back in your WPForms Settings, paste this value into the API Login ID field.

Adding an Authorize.Net API Login ID

Once you’ve added your API Login ID, you’ll need a Transaction Key.

On the API Credentials & Keys page in your Authorize.Net account, look to the section labeled Create New Key(s).

Note: If you have an existing key, you can use it instead of creating a new one. In this tutorial, we’re assuming that you haven’t set up a Transaction Key before or need a brand new one.

For the Obtain option here, select New Transaction Key. Then click the Submit button.

Immediately after submitting, you should see an overlay asking you to verify your identity. Click the Request PIN button to start this verification process.

Adding Authorize.Net Integration to Your Forms

Once you’ve connected Authorize.Net to your WordPress site, you can start adding payment functionality to your forms.

First, you’ll need to create a new form or edit an existing one.

In order for a form to work with Authorize.Net, it must have at least the following 4 fields:

  • Name
  • Email
  • A payment items field (Single Item, Multiple Items, Checkbox Items, or Dropdown Items)
  • Authorize.Net (which collects credit card details)

Note: A Total field is not required for Authorize.Net integration to work. However, it’s helpful for users to easily see how much they’ll be paying.

Once you’ve added any fields you’d like to include in your form, you’ll need to go to Payments » Authorize.Net. From here, check the box labeled Enable Authorize.Net payments.

Next, there are a few optional settings you can configure:

  • Payment Description: This can appear on users’ credit card statements to help them identify transactions from your site. It only applies to one-time payments, not recurring subscriptions.
  • Authorize.Net Payment Receipt: You can select your form’s Email field from the dropdown to send email receipts to users. While optional, we recommend doing this so that your customers have direct records of payment. This option also only applies to one-time payments, not recurring subscriptions.
  • Customer Name: Use this option if you want to send customers’ names to Authorize.Net with their payment details. Just select your form’s Name field from the dropdown.
  • Customer Billing Address: This option will send customers’ billing addresses to Authorize.Net with their payment details. Choose the corresponding Address field from the dropdown.

Note: Want to add customers’ invoice numbers to your Authorize.Net account? See our developer documentation on mapping invoice numbers to Authorize.Net payments.

After you’ve configured these settings, be sure to save your form.

If you’re looking to set up one-time payments, then you’re all set! But if you want to let users purchase recurring subscriptions, or to add conditional logic for your payments, then be sure to continue on to the next sections.

Setting Up Recurring Subscription Payments (Optional)

Recurring subscription payments will process one payment right away, and also process future payments based on the schedule you set.

To start setting up a subscription, go to Payments » Authorize.Net in the form builder. Look for the section labeled Subscriptions and check the box to Enable recurring subscription payments.

Enabling subscription payments for Authorize.Net

Once you’ve enabled this option, additional settings will appear. First, enter a Plan Name for your subscription. This can appear on users’ credit card statements to help them identify transactions from your site. If you leave this box unchecked, the Plan Name will be listed as the name of the form.

You will also need to select the Recurring Period from the dropdown to determine the payment schedule for your subscription.

Next, use the dropdowns to select the corresponding fields from your form for the Customer EmailCustomer Name, and Customer Billing Address.

Finally, you can choose whether or not you want to enable conditional logic for subscription payments. We’ve covered these settings in more detail in the next section.

Enabling Conditional Logic (Optional)

Conditional logic lets you create “smart forms” that automatically change certain aspects of your form based on users’ input or selections. Below, we’ve covered examples of how to use this feature for payments as well as notifications.

Setting Up Conditional Logic for Payments

There are many ways you can use conditional logic with an Authorize.Net payment form. For this tutorial, we’ll use an example of letting users choose whether to submit one-time or monthly recurring payments.

First, we’ll add a selection field to our existing Authorize.Net payment form. We’re using a Multiple Choice field, but a Dropdown field would work, too.

Then we’ll edit the field’s label and choices to include an option for one-time payments and an option for recurring subscriptions.

Creating a Multiple Choice field to set up conditional logic for an Authorize.Net recurring subscription

Once your form has all the conditional fields it requires, you’ll need to set up your conditional logic rule(s). Go to Payments » Authorize.Net and toggle on the Enable Conditional Logic option under the Subscriptions settings.

Enabling conditional logic for Authorize.Net subscription payments

Note: You can also enable conditional logic in the general Authorize.Net settings. Make sure you toggle on the correct conditional logic option for your form.

For our example, we’ll set up our rule to read, Process payment as recurring if Would you like us to automatically renew your plan? is Yes, please auto-renew my plan each month.

An example of a conditional logic rule for Authorize.Net subscription payments

Once this form is published, if users select Yes, please auto-renew my plan each month, then their payment will be processed as a subscription. If they choose No thanks, I want to manually renew, then their payment will be processed as a one-time purchase.

Note: Need help creating your conditional logic rule? See our tutorial on WPForms conditional logic for more details.

Creating Conditional Notification Emails for Completed Payments

By default, WPForms sends out all notification emails as soon as a user submits your form. However, in some cases, you may want to wait to send a notification email until the user’s payment has been successful in Authorize.Net.

To delay a notification email until payment has been successfully completed, go to your form’s notifications settings (Settings » Notifications), scroll to the notification you want to delay, and check the Enable for Authorize.Net completed payments box.

Note: Looking for more details on creating notification emails? Check out our guides on notification emails in WPForms and setting up multiple conditional notifications.

Once you’ve configured all your form’s settings, make sure to click the Save button before you exit the form builder.

Saving a new form

Then you’ll be ready to preview and test your form to make sure it’s working properly before you embed it on your site.
