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.
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.
