Course Overview
The Microsoft course 55104-A: Yammer Development Inside Out is designed for developers, IT professionals, and solution architects seeking to master Yammer platform integration and customization. Although no current certification exam directly maps to this course, it serves roles involved in enterprise social networking, collaboration solutions, and Microsoft 365 development. As organizations increasingly adopt digital workplace tools, demand for professionals skilled in integrating communication platforms remains strong, with Microsoft Viva Engage (formerly Yammer) deployed across thousands of enterprise tenants globally. This course provides essential skills for those tasked with building, managing, and extending Yammer environments within corporate ecosystems.
Students in the 55104-A: Yammer Development Inside Out program work directly with key Microsoft technologies including the Yammer REST API, OpenGraph API, Yammer Embed, JavaScript SDK, and Microsoft Entra ID for authentication. Through hands-on labs in a live Yammer Enterprise environment, learners configure and deploy real integrations such as embedding group feeds into external portals, creating custom OpenGraph objects for dynamic activity streams, and developing applications that post messages and files programmatically. A core project involves building a full-featured integration that tracks user engagement by posting praise events to Yammer and generating corresponding OpenGraph activity items, simulating real-world scenarios used in employee recognition platforms.
While the 55104-A: Yammer Development Inside Out course does not align with a current Microsoft certification exam, it enhances expertise relevant to Microsoft 365 developer and collaboration specialist roles, which are recognized in enterprise IT environments. Professionals with these integration skills report career advancements into cloud solution development and internal tooling roles, with average salaries for Microsoft 365 developers ranging from $95,000 to $130,000 in North America. Koenig Solutions supports learners with 1-on-1 training and Guaranteed-to-Run batches, ensuring access to official Microsoft courseware and practical lab environments. Completing this training prepares individuals to design and implement social collaboration features that drive engagement in modern digital workplaces.
