Our application, which uses the Shopify API to updata our store's product data and get order information, suddenly is getting failed requests a new response error code: 429 (snapshot of the headers of a request below). Has anyone experienced this? What's the correct way to handle this error? And (perhaps more importantly): Where do developers go to find out what changes are coming and when they'll be implemented, so we're not caught by surprise?
