How to get meta fields?

Retired Boards Appdev Partners Discussion

Hi.
I have allocated a lineUID to an undefined metafield using APP in the shop.
I would like to get that lineUID via API, but I can’t get the meta field via custom app.
Please let me know how I can get it.

Which API are you using? Also, which flavor are you using - GraphQl or Rest?

For Admin API using REST it is easy. You can use it with custom app too and it should be available in the current stable realease 2022-07. Check this page: https://shopify.dev/api/admin-rest/2022-07/resources/metafield

For Admin API, GraphQL metafields are currently not available in stable or release candidate. However, if you are brave to use the unstable version - metafields are available. Check here - https://shopify.dev/api/admin-graphql/unstable/queries/metafields

Hope this helps

Thank you for your response.

I am using RESTAPI. However, I am unable to get metafield data.

What is the cause of not being able to retrieve metafield data?

Do I need to configure it by any chance?
Below is what we used to get the data. Please refer to the following.

Hi @LTV-x

Sure, the REST API for customer resource doesn’t have metafields for some reason. However, if you use the API I pointed out in my first reply, the Metafields API, you should be able to retrieve the customer’s metafields.

Here is the endpoint FYR → /admin/api/2022-07/metafields.json?metafield[owner_id]=<CUSTOMER_ID>&metafield[owner_resource]=customer

Also make sure the customer has metafields, otherwise, the response will always be empty!!

PS

(Also just so you know, the GraphQL 2022-07 API does have metafields as well if you want to use it instead)

Hope this helps.

Hi@Mrngodi

Thank you very much for your reply

The following two methods are used to obtain data, but a new problem is that only one piece of data can be obtained at a time.

Please provide instructions on how to obtain multiple pieces of data.

[REST Admin API (Customer)]

/admin/api/2022-07/customers//metafields.json

[REST Admin API (Metafields)]

/admin/api/2022-07/metafields.json? metafield[owner_id]=&metafield[owner_resource]=customer

Thank you

Hi @LTV-x

No problems. I don’t understand what you mean by multiple pieces of data but if your problem is to get metafields for a given customer, I will advice you to use the metafield api

FYR → /admin/api/2022-07/metafields.json?metafield[owner_id]=<CUSTOMER_ID>&metafield[owner_resource]=customer

Make sure you replace the <CUSTOMER_ID> with the actual customer ID

Finally, am sure you know REST APIs work mostly with a single resource. So if you want to be able to fetch data from multiple resources at once, it’s advisable to migrate to GraphQL APIs.

Hope this helps
