    Hello Avnish

    Example of salesforce APIs:

    1. REST API:  is a simple and powerful web service based on RESTful principles. It exposes all sorts of Salesforce functionality via REST resources and HTTP methods. For example, you can create, read, update, and delete (CRUD) records, search or query your data, retrieve object metadata, and access information about limits in your org. REST API supports both XML and JSON.
    2. SOAP API:  is a robust and powerful web service based on the industry-standard protocol of the same name. It uses a Web Services Description Language (WSDL) file to rigorously define the parameters for accessing data through the API. SOAP API supports XML only. Most of the SOAP API functionality is also available through REST API. It just depends on which standard better meets your needs.
    3. Bulk API: is a specialized RESTful API for loading and querying lots of data at once. By lots, we mean 50,000 records or more. Bulk API is asynchronous, meaning that you can submit a request and come back later for the results. This approach is the preferred one when dealing with large amounts of data. There are two versions of Bulk API (1.0 and 2.0). Both versions handle large amounts of data, but we use Bulk API 2.0 in this module because it’s a bit easier to use.
    4. Streaming API: is a specialized API for setting up notifications that trigger when changes are made to your data. It uses a publish-subscribe, or pub/sub, model in which users can subscribe to channels that broadcast certain types of data changes.

    Hi

    SOAP API

    1)Supports data in the form of XML only 2)Requires WSDL for the integration 3)Use SOAP API in any language that supports Web services.

    REST API 1)Supports both XML and JSON format 2)Preferred for mobile and web apps since JSON being Lighter the app runs smoother and faster

    You can also use Apex SOAP and REST Web services to expose data from platform or allow an external application to invoke Apex methods.

     

    Thanks.

    Hi,

    Salesforce Data APIs. They are REST API, SOAP API, Bulk API, and StreamingAPI. Together they make up the Salesforce data APIs. Their purpose is to let you manipulate your Salesforce data, whereas other APIs let you do things like customize page layouts or build custom development tools.

    Web services are of two kinds: Simple Object Access Protocol (SOAP) and Representational State Transfer (REST). SOAP defines a standard communication protocol (set of rules) specification for XML-based message exchange. SOAP uses different transport protocols, such as HTTP and SMTP.

    Hope this helps.
