Shopify updates its APIs to ensure the best possible experience and operations for merchants. Every three months, on average, they deprecate one version and add newer versions.

If you received an email from Shopify Support / Apps Team or see a notification in your store admin interface with the below-given text, you must adjust your Checkify custom app to ensure proper operation.

Subject: [Action required] A developer needs to update your custom apps and/or admin webhooks

All you need to do is simply change some settings in your setup done for Checkify. Please follow the instruction below:

3. In your custom app, select Configuration tab and click Edit button in the Admin API integration section. If you used a Private app to install Checkify then skip this item and go to Step 4.

4. Scroll down and find Webhook subscriptions block. Then select API Version 2023-04 or 2023-07, or higher, but not the "Release candidate" - too early for that :)

If you see that you already have an optimal version selected (not too old, not too new), then do not change anything. In such case you can simply close this guide.

5. Click Save to confirm the action.

You did everything to ensure smooth and secure operation of the custom checkout app :)

If you are experiencing problems at any of the steps described above, you can simply create a new custom app for Checkify's operation. This process will be similar to what you have already done successfully during the initial installation. It is described here.

Get the new set of credentials (API keys), copy and paste them to the appropriate fields in Admin > Settings > Store. Press "Reconnect store" button.

Delete the old custom app after that. It is not advisable to do it earlier in order to ensure the checkout's uptime.

The advantage of such an approach is that all the recent API updates by Shopify are applied automatically, webhooks renewed / re-written.
