What Is a SOAP API?
A messaging specification for information exchange between systems and applications is called Simple Object Access Protocol (SOAP). A SOAP API is designed in a manner that is more structured and codified than other application programming interfaces (APIs). Compare SOAP to the United States Postal Service. Sending and receiving communications across systems (and within enterprise applications) is made dependable and trustworthy with its help. Although it can be slower than rival architectural forms like REST, it is more traditional, well-established, and trustworthy.
