Slack Certified Developer Exam Guide


We are excited you are interested in becoming a Slack Certified Developer! 

If you have experience developing apps for Slack, then becoming a Slack Certified Developer will let you put your skills to the test and share your credentials. You’ll be able to show the world that you have deep knowledge of Slack’s APIs and how to build an effective app within Slack. 

By getting certified, you’ll have the knowledge and skills of successful Slack Developers, leading the way to grow in your career and to change the way that organizations work together. 

You’ll be able to show off your credential to others in your organization or in the broader community of developers building on Slack’s Platform.


The Slack Certified Developer Exam is tailored for individuals with prior experience in Slack app development. We suggest that you have at least six months of hands-on experience with Slack’s APIs and have previously built a Slack app.

A deep understanding of the Slack Platform and app building techniques is crucial for success. We encourage you to take the exam when you feel ready and confident in your journey.

This program aims to sharpen skills and confirm your expertise as a Slack developer. Before taking the exam, you should be comfortable with the following:

  • Understanding the general structure and functionality of Slack.
  • Familiarity with the components and workings of Slack apps.
  • Proficiency in reading and creating JSON objects.
  • Knowledge of Web APIs and event-based API protocols, including JSON over HTTP and, to a lesser extent, WebSockets.
  • Competence in at least one programming language. While NodeJS, Python, and Java are commonly used for building Slack apps, any language capable of handling HTTP API calls is suitable.
  • Experience in developing and deploying a web application, possibly to a cloud service provider.

It’s important to ensure that you have these foundational skills and knowledge to increase your chances of success in the exam. We’re here to support you and look forward to seeing you excel as a Slack Certified Developer.
