note1: form-data vs x-www-form-urlencoded

These are different Form content types defined by W3C. If you want to send simple text/ ASCII data, then x-www-form-urlencoded will work. This is the default. But if you have to send non-ASCII text or large binary data, the form-data is for that. link

note2: What is a Service?

Service is a very loaded term in computer programming that has all sorts of different meanings and connotations depending on the context you are using it in.

A Service in Domain Driven Design is simply a stateless object that performs an action.

note1:

//Equality comparisons
if (strpos('testing', 'test')) {    // 'test' is found at position 0, which is interpreted as the boolean 'false'
    // code...
}

// vs. strict comparisons
if (strpos('testing', 'test') !== false) {    // true, as strict comparison was made (0 !== false)
 // code...
