Office Dev PnP Web Cast – Introduction to Bulk UPA Custom Profile Properties Update API

In this PnP Web Cast we concentrated on Bulk UPA Custom Profile Properties Update API for SharePoint Online, which enables you to update custom profile properties of your end users in batch format. This API will provide you support to synchronize additional APIs to SharePoint Online User Profiles from any system. 

You can configure which attributes are being synchronized from on-premises Active Directory to Azure Active Directory, but due numerous reasons, there’s no support for modifying mapping between User Profiles in SharePoint Online and Azure Active Directory. This means that if you are interested on exposing or using additional custom profile properties in SharePoint Online, you’ll need to get them synchronized there using APIs. Previously this was only possible with one-to-one updates using CSOM, which did not perform that well. Using this batch update API, you can much more efficiently include additional information around your profiles.

Notice. At the time this web cast is released, this capability is ONLY available for first release tenants. Worldwide release cross all tenants is planned to happen during summer 2016. 

Presentation covers following topics:

  • Explanation of the profile property sync process and what this API solving
  • JSON file format for the API
  • Managed code and PowerShell implementation samples
  • What properties can be updated using this API

Demo section concentrates on showing following topics:

What is Office 365 Developer Patterns and Practices (PnP) web cast series?Office 365 Developer Patterns and Practices

Office 365 Developer Patterns and Practices (PnP) web cast series covers different patterns, practices and topics around development with Office 365 and SharePoint. Majority of the topics are valid for the Office 365 and SharePoint on-premises. Our objective is to release new around 30-45 minute long web cast each Monday with few slides and a live demo on the covered topic. All web casts are published at the PnP Channel 9 video blog with additional references on the existing materials.

PnP is community driven open source project where Microsoft and external community members are sharing their learning’s around implementation practices for Office 365 and SharePoint on-premises (add-in model). Active development and contributions happen in our GitHub repositories under dev branch and each month there will be a master merge (monthly release) with more comprehensive testing and communications. Latest activities and future plans are covered in our monthly community calls which are open for anyone from the community. Download invite from

This is work done by the community for the community without any actual full time people. It’s been great to find both internal and external people who are willing to assist and share their learning’s for the benefit of others. This way we can build on the common knowledge of us all. Currently program is facilitated by Microsoft, but already at this point we have multiple community members as part of the Core team and we are looking to extend the Core team with more community members.
