Is the limit on the API calls per store or per app?

[Kabuki_Themes]

Sorry to ask this question again but I am not getting anywhere with my previous post on this.

I initially thought that the API call limit was per store because  in the Shopify documentation it says:

https://docs.shopify.com/api/introduction/api-call-limit#over-api-limit

"HTTP_X_SHOPIFY_SHOP_API_CALL_LIMIT (lists how many calls you've made for that particular shop)"

But then in our app I noticed that we were constantly going over the limit despite abiding by the api limit algorithm, which we implemented per store. So I asked a question of the forum:

https://ecommerce.shopify.com/c/shopify-apis-and-technology/t/api-call-limit-per-store-or-per-app-30...

And an expert said that it was per app. But to be honest I cannot believe this 100% because the documentation seems to contradict it.

Please share your experience, I am sure there are many app vendors who can dimistify this.

Thanks

I still have not seen a clear answer on this question. these 2 sentences I read seem to contradict each other.

I am writing an application that will manage shopify updates for a number of different stores with different api keys. Each stores' updates will be performed independently of eachother (and in different threads).

So, my question is: Will I be forced to implement a single, serialized updating program, that will iterate through all of the stores one at a time? Or can I have multiple threads running simultaneously updating different stores at the same time?

Maybe another way to ask the question is: are the API limits based on API Key or on originating IP address?

Thanks

Hi Brian,

You can interact with the different stores at the same time. Each app installed in each store has its own rate limit.

The quesiton really was:

For a single app, is the call limit per store or per app?

To cut a long story short:

The api call limit is per store

Since we could not get a definitive answer on this one, we decided to test it and found out the answer above. 

Hope that someone from Shopify reopens this thread:

https://ecommerce.shopify.com/c/shopify-apis-and-technology/t/api-call-limit-per-store-or-per-app-30...

and gives the corredt answer, because right now it is blantantly wrong.

The API call limit is per app, per store.

i.e. a particular application can make up two API calls per second on one particular shop.
