1. Enter a **Gateway Title** to easily identify the Affirm account. Then add the **public\_api\_key** and **private\_api\_key** for your Affirm account. It is suggested to keep the **Limits** blank due to the fact that rates are established with each merchant though their agreement with Affirm.
2. Be sure to enter a **Mid**# and an accurate **Descriptor** value. The **Descriptor** is sent to Affirm during transaction processing.

### Step 6: Edit Checkout page and add Affirm button
### Button
#### Step 6-1: It is recommended you place this button either directly below the Shopping Cart Element’s Grand Total field or after the customer input fields on the checkout page since the customer will have to input their address information before being able to checkout with Affirm.
#### Step 6-2: Customize button size by clicking on the button and dragging the highlighted corners or use the Dimension tab for advanced edits. Under the Settings for the element, be sure the Action is set to *Submit + Route*
### Radio
#### Step 6-1(radio): Add a radio button to the page. You may design this to your preference.
#### Step 6-2(radio): Select the radio button and change the settings so the Name is “payment\_method”. This may also be used with the payment toggler by setting the name to “fk-payment-option-toggler“. Then set the Value of the radio button to the name of the pay source in all caps.
