Exploring the capabilities of the plugin reveals that it offers two distinct callbacks upon posting a result: error and success.
The error callback is triggered in cases where the server does not respond with a 200 header. This means that if the server detects validation issues, it can send a 400 response along with relevant text to the client. It's worth noting that standard JavaScript tracking tools like qbaka/GA may not log 400 status responses as errors, though this is subject to verification.
On the other hand, the success callback triggers when the server responds with a 200 header. In this scenario, the server can return JSON data containing error status, which could eliminate the necessity for the error callback altogether.
Considering these two approaches, determining which one is more suitable depends on factors such as the nature of the application, desired handling of errors, and efficiency considerations. Would love to hear your thoughts on this!
