A web API is an application programming interface (API) for either a web server or a web browser. It is a web development concept, usually limited to a web application's client-side (including any web frameworks being used), and thus usually does not include web server or browser implementation details such as SAPIs or web browser engine APIs unless publicly accessible by a remote web application.
A server-side web API is a programmatic interface consisting of one or more publicly exposed endpoints to a defined request–response message system, typically expressed in JSON or XML, which is exposed via the web—most commonly by means of an HTTP-based web server. Mashups are web applications which combine the use of multiple server-side web APIs. Webhooks are server-side web APIs that take as input an Uniform Resource Identifier (URI) that is designed to be used like a remote named pipe or a type of callback such that the server acts as a client to dereference the provided URI and trigger an event on another server which handles this event thus providing a type of peer-to-peer IPC. There are some PHP microframeworks such as Lumen to build a REST API.
Endpoints are important aspects of interacting with server-side web APIs, as they specify where resources lie that can be accessed by third party software. Usually the access is via a URI to which HTTP requests are posed, and from which the response is thus expected.
Endpoints need to be static, otherwise the correct functioning of software that interacts with it cannot be guaranteed. If the location of a resource changes (and with it the endpoint) then previously written software will break, as the required resource can no longer be found at the same place. As API providers still want to update their web APIs, many have introduced a versioning system in the URI that points to an endpoint.
Although "web API" is sometimes considered a synonym for web service, many Web 2.0 web applications have moved away from SOAP-based web services towards collections of RESTful web resources. These RESTful web APIs are accessible via standard HTTP methods by a variety of HTTP clients including browsers and mobile devices. They have advantages over web services in that they tend to be less resource intensive (and thus usually run faster) if they use JSON as message exchange format because in that case they do not need to perform XML-to-programming language data conversions as required by a SOAP-based service APIs.
eSYNCer can provide you with various solutions conceivable for you based on this technology. We make servers available for vendors, which will allow hundreds of customers to run directly on their platforms. For example, retailers wishing to provide linked ecom (webshops) with their product data, and where the ecom (webshops) can communicate with the retailer (the cashier system). This also allows direct 2-way communication. Of course, this is only an example and is very conceivable as a solution.
eSYNCer offers multiple solutions in various sizes and capacities so that the solution is also available to the smaller company. Currently, eSYNCer also provides a leading solution for Lightspeed with our WEB API servers.
We currently have 3 servers available that we fully configure, manage, maintain and scale when needed. Prices per month for these solutions range from € 699.- per month (up to 25 channels) to € 1699.- per month (up to 100 channels), depending on the scale size. Need more or bigger? No problem. We also manage custom made servers.
Looking for a perfect working solution for e.g. processing data through WEB API, among other things? Then fill in this short form on our website and we will contact you within 24 hours.
