What about resource id in path variable vs request param? Our concern is safety
ChatGPT
When it comes to safety and security, using resource IDs in path variables is generally considered more secure than using them in query parameters. Here's why:

Resource IDs in Path Variables:

Less Exposure: Path variables are part of the URL and are less likely to be logged by web servers, proxies, or other intermediaries. This reduces the exposure of sensitive data.

Bookmarking: Resource URLs with path variables can be easily bookmarked by users, and they make more sense for direct access to specific resources.

Caching: Path variables can be more cache-friendly. Caches can better differentiate between different resources based on the path.

Hierarchical Structure: If your IDs have a hierarchical or structural significance, such as /users/123/orders, using path variables makes the structure more intuitive.

Resource IDs in Query Parameters:

Exposure: Query parameters are part of the URL but are more likely to be logged and can sometimes end up in server logs or analytics. This might expose sensitive data.

Filtering and Sorting: Query parameters are often used for filtering, sorting, and modifying the behavior of the request, rather than uniquely identifying a resource.

While using path variables is generally safer, keep in mind that security is not solely determined by whether you use path variables or query parameters. There are additional security practices you should follow:

Validation: Regardless of whether you use path variables or query parameters, always validate and sanitize user input to prevent malicious input or injection attacks.

Authorization: Ensure that users have the necessary permissions to access the resource they are requesting. Just because an ID is difficult to guess doesn't mean a user should be allowed to access it.

Authentication: Implement proper authentication mechanisms to verify the identity of users making requests.

Encryption: Use secure connections (HTTPS) to encrypt the communication between the client and the server.

Access Control: Follow the principle of least privilege and provide access only to the resources users are authorized to access.

In summary, if your concern is safety and security, using resource IDs in path variables is a safer choice due to their reduced exposure, bookmarking capability, and cache-friendliness. However, don't rely solely on this choice; implement a holistic security approach that includes proper validation, authorization, authentication, and encryption.
