When to Use Salesforce SOAP API

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.

• Because SOAP API uses the WSDL file as a formal contract between the API and consumer, it’s great for writing server-to-server integrations.
• You can use SOAP API to create, retrieve, update, or delete records. You can also use SOAP API to perform searches and much more. 
• Use SOAP API in any language that supports web services.

For example, you can use SOAP API to integrate Salesforce with your org’s ERP and finance systems. You can also deliver real-time sales and support information to company portals and populate critical business systems with customer information.
