What is the difference between sending header data and body data?

I am currently building an API using Slim Framework and I've been doing some research on how to send over API credentials/keys. I often see people referring to header information to send the API key. My question is why that method is preferred over sending this data simply via body variables?

Solution

  • It is considered best-practice to have them in headers because that is what they were designed for.
