The Salesforce Certified Slack Developer (exam code Slack-Dev-201) is the exam you pass to earn the Salesforce Certified Slack Developer certification, a credential at the Professional level. It is also connected with related credentials such as Salesforce Certified Slack Administrator. If you are mapping out a certification path with Salesforce, this exam is a milestone worth planning around.

The Slack-Dev-201 exam includes 60 multiple-choice / multiple-select (+ up to 5 unscored questions) questions, and you have 90 minutes to complete them. With that many questions on the clock, pacing is part of the challenge: divide your time into rough blocks as you go, and flag the items that stall you so you can circle back at the end instead of burning minutes on a single question. A week or two before your exam date, sit at least one full timed session in the NewPassLeader test engine under the same time limit, so the pace feels familiar rather than frantic on the day.

You need 67% to pass the Slack-Dev-201 exam, and the official registration fee is USD 200 (retake USD 100). That fee is due again in full for every retake, which makes thorough preparation the cheaper investment by far. Before you book your seat, test yourself with the NewPassLeader practice questions until you are scoring comfortably above the passing mark on a consistent basis — it is the simplest way to avoid paying for the same exam twice.

Recommended: ~6 months experience building Slack apps and working with Slack APIs; knowledge of at least one programming language (Node.js, Python, Java, etc.). No formal prerequisite certification required.

Eligibility rules can be adjusted by Salesforce over time, so before you register, confirm the current requirements on the official exam page: view the official Slack-Dev-201 exam information.
