Client called for slow inventories speed for Shopify store.
So, problem tied with Shopify API call limits:
|Shopify plan||API calls per second||Bucket size|
|Basic, Shopify, Advanced||2||40|
So, possible ways to speed up:
- Use few private apps to break limit (6 private apps means 12 API call per second)
- For Shopify plus possible to call to Shopify to change limits in 5 times (20 API calls per second)
Problem with Shopify API calls limit was solved by using 6 private apps for Shopify Plus account.
