Checkout UI Extension - save order metafield

Retired Boards Appdev Extensions

Hi,

I’m working with Checkout UI Extensions. I need to add a custom block on the “Thank you” page – the target is purchase.thank-you.block.render.

The addition works, but I’m having trouble saving additional order information in the metafield. I’m using:

const applyMetafieldChange = useApplyMetafieldsChange();

However, I’m getting an error in the console:

Cannot call 'applyMetafieldChange()' on target 'purchase.thank-you.block.render'. The corresponding property was not found on the API.

I don’t quite understand how I can save additional information in the metafield. Any hints?

Thank you for your message. I don’t have a website URL; I only have a local version of a test app where I’m exploring the possibilities of the block.

Regarding the details, there will be just one input field where I want to save the entered data in the order details as a metafield. If there are any restrictions, I can save it elsewhere.

Everything is working except for saving to the order details itself. I’m not sure how to do that.

Could you help me with this?
