MCD - API Design Associate (RAML 1.0)
Note: Beginning June 1, 2020, this non-proctored certification exam became available as a free quiz. Existing certifications remain valid for their full 2 year period.
A MuleSoft Certified Developer – API Design Associate should be able to create well-designed, modular API definitions using RAML 1.0 and Anypoint Platform. The MCD – API Design Associate (RAML 1.0) exam validates that an API designer has the required knowledge and skills to:
- Translate design requirements into API resources and methods.
- Use RAML to define API resources, methods, parameters, and responses.
- Model data in APIs using data types.
- Minimize repetition in API definitions using resource types and traits.
- Modularize APIs using libraries, overlays, and extensions.
- Specify API security schemes.
- Version APIs.
- Document and test APIs and make them discoverable.
A downloadable datasheet for the exam can be found here.
- Format: Multiple-choice, open book, unproctored
- Length: 47 questions
- Language: English
This exam can no longer be purchased.
The certification expires two years from the date of passing.
The best preparation for the exam is to take the instructor-led Anypoint Platform: API Design course. Candidates should be familiar with all of the content in the course and be able to apply the concepts in actual projects.
The exam validates that the candidate can perform the following tasks.
