As of February 2023, you can no longer use the Alexa.EventDetectionSensor smart home interface. You can't create new skills or submit updates to existing skills that include this interface.

The Amazon Pay Alexa payments functionality is no longer available to your Alexa skill.
Any skill with Amazon Pay payments functionality will be removed from the Alexa Skills Store. Developers are welcome to re-submit their skill without Amazon Pay for certification to be published on the Alexa Skills Store.
If you want to continue to sell physical goods or services through your skill, you will need to enable customers to link their Alexa account with an account they have with your service and pay using a payment method they provide directly to you. For details, see Add Account Linking to Your Alexa Skill. You can also continue operating the skill for other purposes, such as customer assistance without payment functionality. For further information, see the Alexa Skills Kit. Alternatively, you can choose to disable your skill.
You will continue to find all completed Amazon Pay transactions under Manage Transactions and Payments Reports in your Amazon Pay Seller Central account. You will no longer be able to accept any new Amazon Pay Alexa payment transactions. You can still process refunds or handle claims through your Amazon Pay Seller Central account. Your Amazon Pay Seller Central account isn't impacted and you can continue to offer Amazon Pay in your online shop with your current integration using the Amazon Pay button.
