How do eCommerce APIs function?

The communication between different software systems is facilitated with the eCommerce APIs providing means for feedback between them and allowing data sharing without any hindrance. Here’s how they work:

Request and Response

In a client application, a request is sent to the eCommerce API that is related to the intended action, for instance, item purchase, retrieval of information, etc. The request would generally have the authentication details, endpoint URLs, and any extra data required for the functioning of the operation, amongst other parameters.

Authentication

The API will authenticate a client application using one of the authorization mechanisms – these include, for instance, API keys, OAuth tokens, and others. That way, you will be sure that it is only the authorized users who have the privilege of using the API.

Processing

The API gets the request instruction and takes it as the permission of the app. This includes referring to data sources, calculations, and execution of a previously given business logic.

Data Retrieval/Manipulation

The API fetches the needed information out of the eCommerce platform’s database or completes the action including addition (or insertion of record), update, or delete upon the order of request(s).

Response Generation

Once the process of the request is done, the API sends a response which then contains the request data or confirmation about the action performed. Usually, this answer has a custom and approved format which can either be JSON or XML.

Delivery to Client

A server replies to the client using an API. The data obtained in this way is used to parse it out and then it is sent to the client application for networking use by the network call. For instance, it could be a request that offers information to a user, or it could collect data from the client application itself, or it could execute API calls for further request.

 

API standards and protocols that are set predefined are adhered to by eCommerce, this enables the ecosystem to achieve consistency and interoperability between systems and platforms and hence, integration and communication of software components involved are seamless.
