**Step 2:**

Enter the **apiKey** and **accessToken** credentials received from your WL account. Configure whether the gateway will use **Secure3DS** or not. Enter your dynamic descriptors.

When entering the sslCert and sslKey credentials be sure to enter the full certificate.

**sslCert**

It should start with -----BEGIN CERTIFICATE----- and end with -----END CERTIFICATE-----

**sslKey**

Enter the full key. It should start with -----BEGIN RSA PRIVATE KEY----- and end with -----END RSA PRIVATE KEY-----

**zeroAuth**

WL contains an option to authenticate a card for zero amount. This is an alternative to the Validate Card trial workflow. This can be advantageous for free trial offerings with a 3DS workflow as the consumer should be less confused than with a Validate Card amount on the challenge.

**sendUpsellToken**

Check this box to send for all upsells the payment token returned on checkout. This guarantees a 1-click upsell. If you prefer to send the consumer through a potential 3DS workflow for each upsell, then uncheck this box to send full card details again on each upsell.

**sendProcessor**

Send the processor defined on the gateway setup.  This is used to target a specific processor at WL.

**Step 3:**

Once complete click the green <mark style="color:green;">Create Gateway</mark> button.

**Step 4:**

Apply the gateway to your offers and upsells within the campaign.
