Using Activate Card and Set PIN Widgets
Marqeta provides customizable widgets that enable cardholders to securely activate their cards and set their PINs in your customer web and mobile applications. You can embed these widgets inline as iframes in your web applications. The widgets comply with the Payment Card Industry Data Security Standard (PCI DSS), which defines the security and protocol standards for organizations that store, transmit, or process card data. If you have already obtained PCI Compliance certification, using the Marqeta Activate Card and Set PIN widgets in your web applications is optional.
At the end of this guide, you should understand:
-
What the Activate Card and Set PIN widgets are and when you need to use them.
-
How to create a customized widget to integrate with your web application.
-
How the input to the widgets is validated.
Note
Widgets reduce your burden of achieving data security compliance by providing a PCI-compliant way to allow cardholders to perform certain actions; however, you have other responsibilities regarding data security for other elements of your cardholder experience. Contact your Marqeta representative for details.

Concepts

Data security compliance
Copy section link
You must comply with PCI DSS data security requirements if you want to store, transmit, or process sensitive card data such as the cardholder’s primary account number (PAN), personal identification number (PIN), and card expiration date. The process of becoming PCI DSS certified to store, transmit and process such data directly is both time consuming and expensive. The Activate Card and Set PIN widgets handle the encrypted transmission of sensitive card data, and can help you comply with some aspects of the PCI compliance burden. Marqeta is fully PCI-Service Provider Level 1 compliant, and securely handles the unencrypted, sensitive card data.
Available widgets
Copy section link
The Activate Card and Set PIN widgets are customizable iframes that enable the cardholder to provide sensitive card data to the Marqeta platform. When you embed a widget in your application, your servers never store, transmit, or process the card data so you are not required to be PCI DSS compliant. Embed the iframe in the parent page of your web application where you want the functionality of the widget to occur. You configure the iframe by passing query parameters in the iframe’s source URL. The Marqeta platform then processes the iframe.
Tip
Embed the iframe using a web element when adding a widget to a mobile application. This applies to both Android and iOS.You can integrate the following widgets:
-
Activate Card – Allows authenticated cardholders to activate their program-specific cards.
-
Set PIN – Allows cardholders to set their online EMV PIN code on an activated card.
Upon successful completion, the Activate Card widget renders the Set PIN widget automatically.
The Activate Card and Set PIN widgets apply to many use cases. For example, an alternative lender who leverages an authorized user model might have these widgets display as part of providing loans to businesses. The widgets would enable the business owners to activate their card, then choose their own PIN.
Warning
Your application must provide a login method to authenticate the user. Widgets do not provide user authentication; they only validate that the user-entered data matches the card data on the Marqeta platform.
Widget customization
Copy section link
Before integrating widgets into your application, you must submit your customized style attributes to Marqeta. Marqeta provides the Marqeta Widget Style Preview page as a testing ground for you to determine how you want your widgets to look.
The following styles are customizable:
Style Category | Attributes and Values |
---|---|
Global styles |
|
Form labels |
|
Headers |
|
Button styles |
|
Error message styles |
Errors are displayed above the widget in a flash-message style list.
|
iframe size |
|
Any global styles you define are overridden by more specific style category declarations. For example, if you define a font stack in both the Global Styles category and the Button Styles category, the fonts of the Button Styles stack will apply to the buttons. Other styles are unaffected by this declaration.
iframe parameters
Copy section link
The widgets are accessible from base URLs for both the private sandbox and production environments.
Depending on your environment, use one of the following base URLs as the source of the iframe:
Environment | Widget | Base URL |
---|---|---|
Sandbox |
Activate Card |
|
Sandbox |
Set PIN |
|
Production |
Activate Card |
|
Production |
Set PIN |
Using query parameters, you can specify the language to use when rendering the widget, as well as customize the message displayed upon successful completion of the widget’s task.
Build your iframe content for the desired widget by adding the appropriate query parameters:
Fields | Description |
---|---|
application_id
string
|
The application ID for use with widgets, obtained from Marqeta in Step 2. Allowable Values: A valid application ID. |
one_time_token
string
|
User’s one-time authentication token, generated via Allowable Values: A valid one-time authentication token. |
user_token
string
|
Existing user token. Send a Allowable Values: A valid user token. |
card_token
string
|
Existing card token that is associated with the user token.
Send a Allowable Values: A valid card token. NOTE: Only applies to the Set PIN widget. |
success_url
string
|
HTTPS URL of the page that is loaded in the iframe upon successful completion. The When calling a widget in an iframe, make sure the page provided does not set the X-Frame-Options to If the Allowable Values: A valid URL. |
display_headers

Validation and error handling
Copy section link
The one-time user authentication token you create expires 120 minutes from when the Card Activation widget appears on-screen. The cardholder must complete the card activation during this period. After the Card Activation widget closes, the timer resets to zero to allow the cardholder another 120 minutes to set the PIN in the Set PIN widget.
After the card data has been supplied to the widget, the widget performs a number of validations before sending the data to Marqeta’s servers. The cardholder has five attempts to correctly input data in the Activate Card or the Set PIN widget. After five failed attempts, the widget displays an error message. To try another five times, the cardholder has to refresh the parent web page to force the generation of a new widget.
A cardholder might successfully activate a card using the Activate Card widget, but fail to set a PIN using the Set PIN widget. In this case, the next time the cardholder accesses the widgets, the Set PIN widget appears without displaying the Activate Card widget again.
Warning
There is no way for the widget to inform the parent web page in the event of an error. If the widget encounters an error, the cardholder must refresh the parent web page. Consider providing instructions to the cardholder on how to do this.Activate Card validation
The following validations are performed on the data entered in the widget when the cardholder clicks or taps Activate Card:
-
PAN has been entered in the widget.
-
PAN is a valid card number.
-
CVV has been entered in the widget.
-
CVV is 3 or 4 characters in length.
-
CVV is a numeric value.
If successful, the failure count and the timer are reset to 0, and the Activate Card widget automatically renders the Set PIN widget.
Set PIN validation
The following validations are performed on the data entered in the widget when the cardholder clicks or taps Set PIN:
-
PIN does not contain consecutive ascending or descending values, such as 1-2-3-4 or 9-8-7-6.
-
PIN is not a single digit repeated four times, such as 2-2-2-2.
-
PIN is not one of the most common PINs chosen by cardholders.
-
PIN confirmation value matches the PIN value.
If successful, the page specified by the success_url
parameter is loaded.
Tutorial
Copy section link
This tutorial walks you through how to customize the Activate Card widget and integrate it with a web application in your private sandbox environment.
The Activate Card and Set PIN widgets are not supported in the public sandbox.
Step 1 — Define the widget style attributes
Copy section link
Go to the Marqeta Widget Style Preview page to configure and preview the widget’s styles. Choose attributes that match your web application. Send the finalized styles to Marqeta for implementation when you are ready to integrate a widget into your production environment.
Step 2 — Obtain a new application ID from Marqeta
Copy section link
Contact your Marqeta representative to obtain an application ID, which is a value used specifically for embedding the Activate Card and Set PIN widgets. You must use the same application ID for both widgets. This value is typically provided when you begin working with Marqeta.
Step 3 — Generate a one-time user authentication token
Copy section link
Configure your web application to send a POST
request to /users/auth/onetime
to generate a one-time user authentication token for the logged-in user.
The single-use access token you create for the logged-in user is valid for one request only, and expires five minutes after it is generated.
See the Return single-use token section of the Users page for more information about this endpoint.
The following is an example of a cURL request that generates a one-time user authentication token:
Warning
After the one-time token is redeemed to render the parent web page, it cannot be reused. If the widget times out or the parent web page is refreshed by the cardholder, a new one-time token must be generated and passed to the iframe.
Step 4 — Add query parameters to the iframe
Copy section link
Build the iframe content for the widget by adding the appropriate query parameters from the table in the "iframe parameters" section.
Step 5 — Embed the iframe in the parent website
Copy section link
Embed the iframe in the parent website, using the following as the iframe’s source: https://widgets-sandbox.marqeta.com/activate_card. Since the iframe is requesting an HTTPS domain, the parent website URL must also use the HTTPS protocol.
When completed, the HTML for the iframe should resemble the following:
<iframe src="https://widgets-sandbox.marqeta.com/activate_card?one_time_token=11111111-1111-1111-1111-111111111111&user_token=22222222-2222-2222-2222-222222222222&application_id=33333333-3333-3333-3333-3333&success_url=https://yoursite.com/success_widget.html&display_headers=false"></iframe>
