Headless SDK (Enrollment)

Yuno's Headless SDK gives you full control over the checkout UX and UI to enroll cards without requiring you to be PCI-compliant.

Enrollment Workflow

The following image describes the complete enrollment workflow. Below, each step is described in detail.

Step 1: Create a customer

First, create a customer. After you create a customer, you can enroll payment methods to their account. You can skip this step if you already have a customer ID received from a previous customer creation.

Use the Create Customer endpoint to create new customers and get a customer id. The customer id will be used in the following steps.

Step 2: Create a customer session

Next, create a customer session. Each enrollment needs a new customer session. This session lets you access all available payment methods your customer can enroll in their account.

Use the Create Customer Session endpoint with the customer id to get a new customer_session.

Step 3: Retrieve and display payment methods

Query the available payment methods using the Retrieve Payment Methods To Enroll endpoint using the customer_session. Next, display these methods to the customer so they can select the one they want to enroll.

Step 4: Enroll the payment method

Once your customer selects a payment method, call the Enroll Payment Method endpoint. The Yuno system will check if an additional step is needed to complete the enrollment. The endpoint response will return the enrollment.sdk_required_action parameter:

• If sdk_required_action = true: You need to use the Headless SDK to continue the enrollment. The response will include a READY_TO_ENROLL status, indicating you need to capture payment details from your customer to complete the enrollment. See Step 5 for further information on what to do.
• If sdk_required_action = false: The enrollment is complete, and the status will be ENROLLED or DECLINED.

The Enroll Payment Method endpoint response will also provide the enrollment information and an id. The id is the vaulted_token, which you can save in your system and use to create future payments if the final status received is ENROLLED.

Step 5: Finish the enrollment using the Headless SDK

Follow these steps to complete enrollment using the Headless SDK to capture and share the details of the payment method with Yuno:

1. Include the library in your project.
2. Initialize the SDK with the public key.
3. Configure the SD by calling yuno.apiClientEnroll with the desired configuration.
4. Use the apiClientEnroll.continueEnrollment function to obtain the payment method information, including the vaulted_token and enrollment status.

For more information on how to initiate Yuno's SDK, refer to one of the following pages according to the corresponding platform:

Step 6: Webhook confirmation

The enrollment process is asynchronous. You should use Webhooksto get the final enrollment status.

At the end of the process, you will receive the enrollment status, enrollment information, and the vaulted_token, equal to the id received when in Step 4.
