SOAP API basics
SOAP API (Simple Object Access Protocol API) can be used to create, retrieve, delete, update records. We can use SOAP API in any language that supports web services.
We can create, update, delete, retrieve records in force.com from any external system that supports SOAP based web services by using force.com SOAP API (like Java, .net etc.…) with more than 20 different calls.
SOAP-API also allows you to maintain passwords, perform searches, retrieve metadata.
Salesforce provides two different SOAP API WSDLs (WSDL: Web service description language).
1. Enterprise WSDL
2. Partner WSDL
What is WSDL?
WSDL (Web service description language) is an XML document which contains a standardized description on how to communicate using a web service.
