synchronous/asynchronous API

Contributor(s): Matthew Haughn

Synchronous/asynchronous APIs are application programming interfaces that return data for requests either immediately or at a later time, respectively. Synchronous/asynchronous APIs provide a way to make immediate or scheduled requests for resources, data or services when available.

The synchronous and asynchronous nature of an API is a function of the time frame from the request to the return of data. In the case of synchronous APIs, the expectation is that there will be an immediate return of data. The application requests data and waits for it until a value is returned.

In the case of asynchronous APIs, the availability of a resource, service or data store may not be immediate. These APIs may provide a callback to the requester when the requested resource is ready. Asynchronous requests are useful in maintaining functionality in an application rather than tie up application resources waiting on a request.

An API may be synchronous where data or service availability, resources and connectivity are high and low latency is a requirement. An API may be asynchronous where data or service availability and connectivity are low or oversaturated with demand.
