API Rate Limits Question

[DanielROI]

Can anyone explain the API rate limiting factors?
I read that it is 4 requests/sec for Advanced, but I also see documentation on a "leaky bucket" algorithm that allows some room for bursting. Anyone know what the bucket size is for Advanced? For Plus?

Hi there 👋

You should find the bucket size, and request limits in the following documentation for each plan.

API	Rate-limiting method	Standard limit	Advanced Shopify limit	Shopify Plus limit	Commerce Components by Shopify limit
Admin API (GraphQL)	Calculated query cost	50 points/second	100 points/second	500 points/second	None
Admin API (REST)	Request-based limit	2 requests/second	4 requests/second	20 requests/second	None
Storefront API	None	None	None	None	None
Payments Apps API (GraphQL)	Calculated query cost	910 points/second	910 points/second	1820 points/second	None

Thank you. Can you tell me what the bucket size is for the "leaky bucket"
algorithm for Advanced/Plus? I do not see that in the documentation.

Hi

Sorry about that, you should see it in the documentation here.

Basic

• Bucket size: 40 requests/app/store
• Leak rate: 2/second

Plus

• Bucket size: 400 requests/app/store
• Leak rate: 20/second

Thank for the further information. In other documentation, the rate is
2/sec Basic, 4/sec for the Advanced plan and 20/sec for Plus. I only see
"Standard" bucket limits. Do you know what happens to the bucket limits in
the Advanced?

[lizk]

I just confirmed with the team that the bucket size increases with the same interval as the leak rate for advanced. 

So you can expect the bucket size to be 2x the Basic Plan so: 
Advanced: 

• Bucket size: 80 requests/app/store
• Leak rate: 4/second

This is talked about on the docs and I'll past something from it below
https://shopify.dev/docs/api/usage/rate-limits#the-leaky-bucket-algorithm

Those on the Plus plan get higher rates but all others follow the defaults.

The bucket size and leak rate properties determine the API’s burst behavior and request rate.

The default settings are as follows:

• Bucket size: 40 requests/app/store
• Leak rate: 2/second
