A customer can create its own robots.txt file for three valid reasons:

• The customer wants to reference multiple storefront sitemap indexes in a single robots.txt file. This can be useful if the customer has multiple storefronts under the same domain and wants to provide a single entry point for search engines to crawl their sitemaps.
• The customer wants to reference a custom sitemap index. This can be useful if the customer has created their own sitemap index that contains custom sitemaps or sitemaps from other sources.
• The customer’s store is not located at the root of their domain. This can be useful if the customer has their store under a subdirectory or a subdomain and wants to specify a different robots.txt file for their store than for their main domain.

To make an API call in a Lightning web component (LWC), a developer should use the connectedCallback lifecycle hook. The connectedCallback lifecycle hook is invoked when the component is inserted into the DOM. This is the ideal time to make an API call, as the component is ready to receive and display data. Thedeveloper can use the fetch API or a third-party library, such as axios, to make the API call and handle the response. The renderedCallback lifecycle hook is not a good choice for making an API call, as it is invoked every time the component is rendered or rerendered. This can cause unnecessary or repeated API calls and affect performance. The errorCallback lifecycle hook is not a good choice either, as it is invoked when an error occurs in the component or in one of its children. This is not related to making an API call, but rather to handling errors. The disconnectedCallback lifecycle hook is not a good choice either, as it is invoked when the component is removed from the DOM. This is not a suitable time to make an API call, as the component is no longer visible or active.

For investigating errors during development, Salesforce recommends using the Streaming API Subscription Channel for Commerce Diagnostics Event Logging. This tool allows developers to subscribe to a real-time feed of system events, including errors, which can be crucial for diagnosing and resolving issues during development. The Streaming API provides a robust mechanism for monitoring and debugging by delivering secure, scalable, and customizable event notifications within Salesforce or through external systems. This is outlined in Salesforce documentation related to the Streaming API and its application in commerce diagnostics and event logging.
