Update Passes Classes and Passes Objects
Stay organized with collections Save and categorize content based on your preferences.

Keeping passes updated is an important way to engage with your customers and build a positive experience.

There are two resources that can be updated: The EventClass and the EventObject.

Best Practices

The following list contains helpful information to consider when updating your event ticket classes and objects:

When you want to update an entire class or object, send an update request. When you want to update a small number of fields in a class or object, send a patch request.
When you make an update request, the entire object or class is updated. This means that any fields not included in the request will be cleared. Before sending an update request, we recommend you send a GET request to ensure you are working with the latest version and all of the intended fields are included in your request.
When making a patch request, only the patched fields are updated. Before sending a patch request, consider optionally sending a GET request to compare your changes against the latest version.
When making patch requests to update arrays, the original array is replaced with the one included in the request body. You cannot modify the elements in an array individually.
In some cases, you may not know when changes happen, or when to trigger updates. Consider periodically scheduling update or patch requests for all classes and objects.

Update a Passes Class

Use the Google Wallet Business Console

Pass classes (not objects) can be modified directly in the Google Pay & Wallet Console.

Navigate to the console
Select Google Wallet API
Select the class you want to modify
Select Edit
Update the class properties
Select Save

Once you save your changes, the class is updated automatically for any eventticket holders.

Use the Google Wallet API

Updating the EventClass affects all users who have been provisioned event tickets using this class. For example, to update the logo for your event tickets, you would submit an update or patch request to the Google Wallet API at either of the following endpoints. The resourceId value would be the class ID (ISSUER_ID.CLASS_SUFFIX).

# Update
PUT https://walletobjects.googleapis.com/walletobjects/v1/eventticketclass/{resourceId}

# Patch
PATCH https://walletobjects.googleapis.com/walletobjects/v1/eventticketclass/{resourceId}

For more information, see the API reference.

Update a Passes Object

Updating an individual EventObject affects only the user who has been provisioned that specific object. You should regularly update individual event tickets to reflect changes that affect your customers and keep them engaged. The resourceId value would be the object ID (ISSUER_ID.OBJECT_SUFFIX).

# Update
PUT https://walletobjects.googleapis.com/walletobjects/v1/eventticketobject/{resourceId}

# Patch
PATCH https://walletobjects.googleapis.com/walletobjects/v1/eventticketobject/{resourceId}
