Automate alt textes to customer media uploads

Hello,

I am having problems separating the media uploaded by customers against our own. They are uploading via meta fields by helium customer fields.

Can I automate adding alt text to customer-uploaded images using Shopify Flows?

Hi @hugobb3 ,

Shopify Flow doesn’t natively support image processing or manipulating metafield media.

Else you can use the following option-

Automatically add alt text to customer-uploaded images via Helium Customer Fields in Shopify.

Customer uploads image via Helium → saved in a customer metafield (e.g., custom_fields.uploaded_image).

Create a backend script that-

Uses Shopify Admin API to fetch the image metafield.

Gets the file ID or URL from the metafield.

Uses GraphQL fileUpdate mutation to set the image’s alt text.

Automate the script:

Trigger on Helium webhook (if available), or

Run a daily cron job to check for new uploads and update alt text.

Let me know if you need a detailed overview of this solution.

Thanks
