It's old news that applications rely more and more on APIs.
I've recently talked about Akamai that estimated, in 2018, that 83% of Internet Traffic is now API-traffic.
More recently, we have explained that using an application performance monitoring (APM) tools let you provide metrics on the inner workings of your application. But sometimes, you need more details about the API calls (aka the logs of the request, its headers, its body, etc.).
One of Bearer key features is that it can log all external API requests by instrumenting the HTTP core module of most backend programming language, including: Go, Python, PHP and of course Node.js. There's no magic here and the team has recently explained on our blog how we did it in Node.js. The link is in the comment.
