There are lots of examples of API implementation requirements, but let’s just take a look at a couple of security specifics for SOAP and REST. Examples of API Implementation Requirements There are also implementation requirements - which are typically heavy on security. This is true for any non-functional capability, including logging and failover.īut functional and nonfunctional aren't the only requirements for APIs. For example, if a particular security mechanism was applied to an API, but other consumers required a different security mechanism, that API is not reusable. It's important to address nonfunctional compatibility for APIs.
#Functional requirements software
Usually measured as response-time or throughput.Ībility with which the software performs its required functions under stated conditions for a specified period of time.Ībility with which the software copes with errors during execution.Ībility with which the software handles growing amounts of work in a graceful manner.ĭegree to which the software protects against threats.Įase with which the software can be used by specific users to achieve specific goals.
Nonfunctional API Requirement Examples Nonfunctional API RequirementĪbility with which the software respects the specification.Įase with which the software is doing the work it is supposed to do. Here are some examples of nonfunctional API requirements. But none of them have anything to do with the business process or domain of the API’s resource. Implementing non-functional requirements by declarative policies is much quicker and easier than implementing functional requirements.īecause of the differences between them, it’s important to separate out these two types of requirements.Īvailability, scalability, logging, security, and performance are all critical to the successful use of an API.Non-functional requirements are much more variable than functional requirements.There are two big differences between functional and non-functional requirements: Enabling the connection of a new business to the existing enterprise.Įxamples of API Nonfunctional Requirements.Some examples of how APIs will be used include the following functional requirements: For example, an API that’s being used to perform financial transactions will have more constraints than one delivering advertisements. The way in which the API will be used affects several issues such as the technology choices, regulatory issues, and security. 📕 get the Report Examples of API Functional Requirementsįunctional requirements define what the API does and how the API will be used.
