What causes Shopify error 429 too many requests

A 429 too many request error generally triggers when an app receives more API calls than it allows.

Shopify uses API rate limit to ensure the stability of the platform. They use it to control the number of requests that any app can make on the platform.

Different types of rate-limiting methods are available, which include calculated query cost, request-based limit etc.

Whenever the API calls exceed the limit, it triggers this error. A typical status code looks like this:

How to fix Shopify error 429 too many requests

As the Shopify error 429 triggers mainly due to the API rate limit, the first step to fix the error would be to find the number of API calls being made to the app. Also, we may need to figure out if most of them are repeated searches or not.

We can find the number of API calls being made from the app’s developer settings. Once we are aware of the number of API calls and their types, there are two ways to go about solving this problem:

• Increase the “rate-limit” of the app. For example, we may need to increase rate-limiting from 100 to 10,000 API calls a day. For this, we may require  to upgrade your account type with the app.
• Decrease use of the API calls. For instance, it may be possible that the app is receiving about 8000 requests while the permitted limit is 1000. If 7000 of those request are repetitive, decreasing the API calls would be enough instead of upgrading the app.
