Mulesoft Certified Developer (Mule 4)

Explore how application networks enable app-to-app communication through APIs, using the menu analogy to explain specifications, systems of record, and API as a middleman, with lifecycle and standards.

Explore rest as an architecture for communication, not a protocol, emphasizing client-server separation, statelessness, and caching. Cover security pillars like authentication, confidentiality, integrity, and non-repudiation using encryption and hashing.

Explore API-led connectivity: organize data into system, process, and experience layers to unlock data and enable reusable APIs for third-party developers through a center for enablement and asset consumption reuse.

Design APIs using RESTful principles, explore HTTP methods such as GET, POST, DELETE, and PATCH, and use JSON as a lightweight, human-readable data interchange format.

Create and test a RAML API blueprint in the design center, defining a planets endpoint with get methods and an id-based retrieval, plus mock responses and 200 json examples.

Publish your API spec to Anypoint Exchange, share it with stakeholders, and explore the API designer, mocking service, and versioning options for cloud or on-premise deployments.

Discover how the Anypoint Platform builds a structured application network with API-led connectivity, using Anypoint Exchange, Design Center, API management, and access control to manage organization assets and APIs.

Explore assets content types in MuleSoft: connectors, templates, and examples, and learn to create these assets manually or with Design Center, Maven, or Anypoint Studio, including API spec fragments.

Understand semantic versioning 2.0 to signal incompatible API changes with a major version bump, use a minor version for new functionality, and a patch version for bug fixes.

Explore API manager for end-to-end API design, import possibilities, policies and analytics via API gateway, and Anypoint MQ, a cloud enterprise messaging service with REST API, encryption, and two-week TTL.

Explore CloudHub, a secure, multi-tenant integration platform as a service with intelligent healing and zero downtime updates. Understand its runtime manager, console, and deployment options from cloud to on-premise.

Build a real API with flow designer in the design center, turning an EPA spec into a running flow that serves planet data via triggers, operations, and JSON payloads.

Learn how to set up and launch Anypoint Studio, configure Java and environment variables, create a Maven-based project, build and deploy a simple API, and test it with postman.

Learn to generate groups using the API, configure APIKit to connect to a MySQL database, run selects, and transform results into API responses.

Publish the API to the EPA exchange and deploy to cloud hub, packaging the project and using design and sandbox environments to track deployment.

configure and deploy an EPA proxy gateway, apply rate-limiting policies and SLA tiers, and manage client credentials to safeguard and control api access.

Create a Mule 4 project, configure a listener on /launch, and set a payload showing the rocket has been launched. Debug with breakpoints and step through processors.

Learn flows in Mule 4 by connecting a regular floor to a sub floor with an async scope and floor references, publishing via a VM connector and logging rocket launched.

Master the core data expression language, including pattern matching, string interpolation, and flow controls like do, with external functions. Explore map, flatten, join, distinct, match, and max.

Learn to convert between json and xml with the transform message connector, preview json and xml outputs, and access first-record values using dot notation.

Explore advanced error handling in Mule 4, including continue or propagate flows, custom errors, and the default behavior and success and error responses of Mule listeners.

Learn to synchronize data using api or applications and automate file transfer between folders with a connector, on new or updated triggers, and a one-second polling schedule.

Compare for each and batch scope usage in Mule 4, convert CSP files to Java objects, process payloads, and log results for efficient, configurable record handling.

Practice with mock exams to understand question types and focus topics, then prepare to become a MuleSoft certified developer level one for Mule 4.
