Get Cloudy Consulting (GCC) wants to integrate its financial system with its Salesforce environment.

 The tool that GCC should use to build an integration between its financial system and its Salesforce environment is MuleSoft. MuleSoft is a platform that enables companies to connect any application, data, or device using APIs. MuleSoft helps GCC to create and manage integrations between Salesforce and other systems, such as its financial system, without writing any code. MuleSoft also provides prebuilt connectors, templates, and best practices to speed up the integration process
