API Design Associate (RAML 1.0) Certification

With the MuleSoft Certified Developer – API Design Associate (RAML 1.0) exam, you can prove your ability to create API definitions with RAML 1.0 and Anypoint Platform.

Gain this qualification to display your status as a fully certified MuleSoft Certified Developer – API Design Associate.


Certification Objectives

Take the MuleSoft Certified Developer – API Design Associate (RAML 1.0) exam to show your knowledge of:

  • translating design requirements into API resources and methods
  • using RAML to define API resources, methods, parameters, and responses
  • modelling data in APIs using data types
  • minimising repetition in API definitions using resource types and traits
  • modularising APIs using libraries, overlays, and extensions
  • specifying API security schemes
  • versioning APIs
  • documenting and testing APIs and make them discoverable

MuleSoft Certified Developer – API Design Associate (RAML 1.0) Exam: Format

  • format: multiple-choice, open book, unproctored online or in a testing centre
  • length: 47 questions
  • duration: 90 minutes
  • pass score: 75 percent
  • language: English
  • the exam can be taken a maximum of five times, with a 24-hour wait between each attempt

Delivery Methods

You can choose to take the exam in-person at a testing centre or online using a web camera, administered via the Kryterion Webassessor testing platform.

If you choose in-person at a Kryterion Testing Centre:

  • over 1000 locations worldwide
  • onsite instructions
  • a test-taker guide

If you choose online using the Kryterion Webassessor testing platform:

  • requires a webcam – a laptop webcam can be used, an external camera is not required
  • requires internet connectivity with 1 Mbps upload, 1 Mbps download, jitter <50ms, ping <200ms
  • use the tool to determine your internet speed and reliability
  • online instructions
  • a test-taker guide

If you think your connection might be unreliable, we recommend you choose a testing centre instead. An unreliable connection may cause you to be expelled from the exam.

Exam Preparation

  • we recommend taking the instructor-led Anypoint Platform: API Design course as preparation for this exam
  • candidates should be familiar with all the course content and be able to apply it before taking the exam
