Migrate Asset API to Theme App Extension

[xao0isb]

Since the Asset API works until april 2024 we have to migrate to the Theme App Extension.

Our app is currently creating new .liquid files and change them using the Asset API. But how can I achieve the same functionality through Theme App Extension? I didn't find any info in the documentation and across google.

Thanks!

Hi Xao0isb,

With theme app extensions, you won't be able to create new liquid files - instead your app will need to integrate within a liquid template as a block that can be added to a section. This is an intended limitation to ensure merchants who install apps from the Shopify app store continue to have performant stores. If your app cannot migrate without losing functionality you can apply for an exemption to this requirement on this form.

Hope this helps,

Hello Liam,

is this form only for current apps looking to migrate or also for new apps that require to create liquid files?

[Liam]

This form is just for existing apps on the Shopify App Store. For new apps you'll need to contact partner support directly from your partner dashboard to request an exemption.
