Certified candidates should be able to:

• Use MuleSoft-hosted Anypoint Platform to take a basic API through all the steps of its lifecycle: design, build, deploy, manage, and govern.
• Use Anypoint Studio to build, test, and debug basic integrations and API implementations.
• Connect to a range of resources including databases, files, web services, SaaS applications, and JMS queues.
• Perform basic data transformations using DataWeave 2.0.
• Control event flow and handle errors.
• Process batch records.
