Gateways of communication, system/automated access to data and configuration. Exchange data with other systems in your company

SOAP API

SOAP/WSDL2 Versions:Enterprise: Strongly typed, Org specificPartner: Dynamic, Requires datamodel inspectionExtensive API, well suited for system integrations

Custom APIs

Apex codeSOAP or RESTXML, JSON or custom formatsSynchronousWrite your own API in Apex

webService static SOAP

Custom APIs Use Case

Challenge: External mobile application needs to store multiple records in multiple objects in a transactional process.Issue: REST Api handles insert and update calls in separate requests per record

Solution: We wrote our own custom Apex REST endpoint to accept a custom datatype which was wrapper around the salesforce sObjects. Now we could handle the transactional process in Apex.
