Solution: "Exceeded 4 calls per second for api client" Python Shopify API - shopify_python_api

Solution for API call limit "shopify_python_api"

If you are using Python Shopify API and getting following error
"Exceeded 4 calls per second for api client. Reduce request rates to resume uninterrupted service."
but want your script to continue working with some timeout after that,
you can use following script from shopify_limits_patch.py.

For that just copy shopify_limits_patch.py to your project and import shopify_limits_patch.

Or if you want to call it implicitly import it, remove last line patch_shopify_with_limits()
and call it before all your shopify calls.

This is solution for issue described here: Shopify/shopify_python_api#256

If you have any suggestions for code - leave comment :)

shopify_limits_patch.py

import time

import pyactiveresource.connection
from shopify.base import ShopifyConnection


def patch_shopify_with_limits():
    func = ShopifyConnection._open

    def patched_open(self, *args, **kwargs):
        while True:
            try:
                return func(self, *args, **kwargs)

            except pyactiveresource.connection.ClientError as e:
                if e.response.code == 429:
                    retry_after = float(e.response.headers.get('Retry-After', 4))
                    print('Service exceeds Shopify API call limit, '
                          'will retry to send request in %s seconds' % retry_after)
                    time.sleep(retry_after)
                else:
                    raise e

    ShopifyConnection._open = patched_open


patch_shopify_with_limits()

validation.py

import os
from threading import Thread

import shopify

import shopify_limits_patch


def foo():
    for _ in range(15):
        shopify.Variant.find()

def main():
    # Add your Shopify URL here: "https://<shop_name>.myshopify.com/admin"
    shopify.ShopifyResource.set_site(os.environ.get('SHOPIFY_URL'))  

    for i in range(15):
        t = Thread(target=foo)
        t.start()

if __name__ == '__main__':
    main()

Still working in 2024!

It works perfectly in late 2024, the only change i made is

retry_after = float(e.response.headers.get('retry-after', 4))

I created a shopify_patched module, and inside the init file, i added

from .shopify_limits_patch import shopify

To import the library, i replaced all:

import shopify

with

from app_api.api_modules.shopify_patched import shopify

Is that correct?

@b4p3p yeah, this way of import also works. Probably even better than proposed in 2018 😅
Can't check if 'retry-after' should be lower cased or any other. But people that use it - can easily do that.
