Get all metafields for products

[ReloadSEO]

This has been posted before, but the Shopify support hasn't answered it yet... And it is a good and reasonable question. 

I want to get all the metafields for all the products.

My understanding is that there is no API like:

/admin/products/metafields.json

The only one is like this:

/admin/products/#productid#/metafields.json

Therefore, the only way is to get all the metafields for all the products is to make one API call per product!

It is also impossible to cache the data, because it takes one API call per product just to check if the metafields for that product have been updated!  For large stores, it is handicapping API applications and forcing one call per product, resulting in extremely time-consuming fetches for tiny amounts of data.

Can you please add an API call that works like this?  /admin/products/metafields.json

It would return all the metafields for all the products, 250 at a time.  We can then page through in a reasonable amount of time.

Or, does anyone know some other workaround to get all the product metafields at once?

Hey ReloadSEO,

There's currently no way to achieve this through the current API. However, we're aware that this is something that developers are interested in and we're actively looking into finding a solution.

Keep an eye on the API Announcements forum for any updates regarding this.

Cheers,

Jamie

Just run into this problem myself. Haven't been able to find a workaround sorry. I agree with your request to extend the API though and would like to add that /products should be able to return metafields_global_title_tag and metafields_global_description_tag (if it doesn't already, maybe there's a way to specify the fields value of the request for it?).

Hi Jamie,

please include the functionality so to get all metafields for certain ids (add ids[] paramter). I'd like to get the metafields for a list of products (i.e. metafields for all products in an order).

Must say I am very disappointed to see this lacking the API and also finding threads that are more than two and a half years old on this topic. 

Please commit to a production date (or sprint, release) for these updates.

Best regards,

Thomas

I am also interested in more information here. What is the intended use/meaning of this section of the docs pertaining to metafields? This makes it look like we should expect to be able to obtain product metafields at the /admin/metafields.json resource, and filter for conditions; however when I tried this on my store, only the 'store' metafields were returned. Accessing metafields a single product at a time is not at all an efficient use of the limited API call resource. Really need someway to obtain this information in a single, or a few, calls : 

https://texansaddles-com.myshopify.com/admin/metafields.json?metafield[owner_resource]=product

I was able to pull a single product metafields at the following address, but this is a duplicate of the resource at /admin/products/{id}/metafields.json:

https://texansaddles-com.myshopify.com/admin/metafields.json?metafield[owner_id]=6107959043&metafiel...

From the Docs:

GET/admin/metafields.json

Get metafields that belong to a product image

Get all metafields that belong to the images of a product

GET /admin/metafields.json?metafield[owner_id]=850703190&metafield[owner_resource]=product_image

It was also frustrating to find that the metafields for a product are not included in that product's json when called at /admin/products/{id}.json, or as part of the list from /admin/products.json. This would have been an intuitive way to access metafields associated with products.

[Mitchmaster]

I find it hard to believe that Shopify has been "researching a solution" to this problem for years. It should take 10 minutes of programming to solve given that identical capabilities already exist at other levels of the API. Having to do a separate curl call to find out if each product has a given metafiled makes this useless for a live page - it can take up to a minute to load. Please expedite a solution!

[Jonathan-HA]

+1 for this. Would also be nice to be able to specifiy a list of product_ids and get the metafields for them.

We have a CSV exporter app and one of our customers asked if we could include metafields in the report. With the current API implementation, it's too expensive to make an API call for each unique product included in the report.

Any updates here?
This is needed, otherwise the metafields are stuck in a far off land with the API call limit.

Thanks HunkyBill. 

Maybe you could help me figure out the logic for this.

I'm creating a private app for my client. I was hoping to use metafields to allow us to change a binary option (true/false) for each customer.

In my app I list all of the customers in the shop, and ideally I'd like to display this metafield within the list as well.

Ex. First Name, Last Name, Address, Binary Metafield, etc

I obviously have the /customers.json GET working properly with all customer info, now I'm working on the metafields.

How could I grab this metafield for each customer, without making x # of requests (depending on how many customers)?

I hope this isn't an extremely simple solution, but I can't think of any way around the API limit for this. 
I've just started using the Shopify API (yesterday) so I am a bit new at this.

Thanks HunkyBill!

[HunkyBill]

You get 250 customers per API call. for each customer, add a metafield. 

simple. 

You can modify the theme to display the metafield values too, in the customer Liquid files. 

[bolle]

Sorry, I meant I need to GRAB that metafield value for each customer in the API.

My original thought - grab customers.json , for each customer in there, grab the id and send another request to Shopify for metafields.json with that user id. 

That should work technically, but if there are 40+ customers I'm going to hit the limit quickly.

[HunkyBill]

You can GET 250 customers in one API call. You won't hit the limit if you page through them like that. And even if you did throw 40 calls out (10,000 customers later).. you still get 2/second. About the API limits... there is a ton of code out there about how to deal with limits in any language except probably COBOL... 

So get 250 customers at a time, and deal with their metafields... and if you hit the limit... big deal.. you wait a 0.5 seconds to make your next API call... 

[bolle]

Wonderful. Thanks I'll try it out.

Bad pseudocode below - 

Would something like this work (away from pc at the moment):
 

GET customers.json (lets say all 250 customers) {

for each customer in customer.json {

GET metafields.json?metafield[owner_id]=user.id&metafield[owner_resource]=customer {

return data;

}
}

[HunkyBill]

yes... that will work fine... 

[Paul_Younger]

If I understand correctly, I should be able to get up to 250 product metafields with this call:

admin/metafields.json?metafield[owner_resource]=product

However, I get this as a response: (metafields do exist for products)

 {"metafields":[]}

[HunkyBill]

I think you're better off getting a product, and asking for all it's metafields. Asking for metafields that have an owner is kind of chaotic. I think that only works if you also provide an ID. 

[Dennis2]

I would say something like this should work:

/admin/metafields.json?metafield[owner_resource]=product

This way you only request resources for product and you could even make namespace required for example. Or just providing a list of resource IDs (products IDs for example) would work as well, I guess. Al long as you don't have to download all metafields for each resource one at a time would work for me 🙂

[Paul_Younger]

Dennis, that did not work for me.  Note my previous post.  Results were empty.

[HunkyBill]

As I told you. Asking for metafields by using some generic resource owner like "product" is chaos. There is little to no chance Shopify would support that as an ad-hoc query as it is expensive to gather those resources easily and cheaply. 

So function in the normal way. Get your products of interest first, and then get their metafields. It is not complex and it is guaranteed to work.
