Hey Christopher. You can read more about what a user agent is at this
helpful link from Mozilla. In short, they are used in every web request to indicate the type of software making the request. In many cases, its just your browser version. If you were to make the call from Pipelines, that would have its own user agent. Because those are so helpful in troubleshooting issues, we surfaced it in the new APIs to encourage people to be passing one. If you use an SDK for example, those usually automatically fill them in with something like "MyNodeSDK/V1.1". If you used Qunect, that passes the user agent to us. But if you wrote your own code and hosted it somewhere, it probably isn't generating it out of the box. So the best thing to do is pass something descriptive. Let's say you built a piece of software to generate monthly invoices and your company name was GreeneCo. You might create a user agent like "GeeneCo/V1.2". By doing that, our teams are able to quickly identify where things are coming from and help you more effectively when you have questions.
