How do developers achieve bulk updates through Shopify admin API to change metafields of products in the store?
We want to do this through our app with as minimum API calls as possible.
Thanks in advance for any help/suggestion.
At this time, we don't offer any kind of bulk metafield updating mechanism through our API. If your concern is with hitting the call limit, this blog post offers some nice strategies for both budgeting/planning/conforming to our leaky bucket algorithm efficiently and an approach to applying multiple metafields to one resource with less calls.
