API rate limit error in order API

[Divy_tatva]

Hello

In the development store, I am updating orders with PHP curl. But it's updating only 2 orders every time and after that showing this error => "errors": "Exceeded order API rate limit, please try again in a minute. Upgrade to a paid account to remove this limit. in Shopify during order updates.

I have used the below headers still only updated 2 orders.

X-Shopify-Shop-Api-Call-Limit: 40/40
Retry-After: 2.0

what is the cause of this issue?

Thank you

Hi Divy_tatva,

It sounds like the issue you are facing is related to rate limits - you can learn more about these in our dev docs here.

It may be that you're sending requests too quickly, which is why you're only able to update 2 orders at a time. To resolve this issue, you need to manage the rate at which you're sending these requests. You should ensure that your PHP script waits for at least the Retry-After period before sending another request.

Hope this helps,

try a

sleep(1); // pause 1 second

in your script after each update.
