Types Of APIs In Salesforce
The most widely used APIs regarding Salesforce are of two types:
1. REST API
REST stands for “Representational State Transfer”. The Force.com REST API lets you integrate with Force.com applications using simple HTTP methods, in either XML or JSON formats, making this an ideal API for developing mobile applications or external clients.
2. SOAP API
SOAP stands for Simple Object Access Protocol. The Force.com SOAP API (formerly the Force.com Web Services API) lets you integrate Force.com applications to create, retrieve, update, or delete records managed by Salesforce, Force.com, and Database.com, such as accounts, leads, and custom objects.
But Also, the third one is Metadata API which is used to manage and build customization within Salesforce.
