Rest API Query Variant with UPC

[pythagoryan]

Hello!

Straight up, I don't have a lot of experience working with APIs. I'm mostly a front-end developer.

I'd like to send out an API call from Zapier to return a product based on the UPC.

I'm definitely doing this wrong but here's what I set up:

Any help is appreciated! Thanks in advance!

If the service allows GraphQL api access then use that instead to query variant by barcode.

https://shopify.dev/docs/api/admin-graphql/2023-01/queries/productvariants#argument-productvariants-... 

For REST refer to the reference

https://shopify.dev/docs/api/admin-rest/2023-04/resources/product-variant

There is no barcode parameter to query in a productVariant in the REST api

So using the REST api you need to just get all the variants, using pagination, then filter down to the barcode after you have them all in the automation service.

Alternatively use that automation tool, or yet another automation tool like  mechanic , to premake a data structure or an endpoint that uses the barcode as a key for the variants data.
