SharePoint PnP Webcast – Getting started with SharePoint Webhooks

In this PnP Web Cast we concentrated on showing how to get started with upcoming SharePoint Webhooks. SharePoint Webhooks allow developers to build service integration which subscribe to receive notifications on specific events that occur in SharePoint. When one of those events are triggered, SharePoint will send a HTTP POST payload to subscriber. SharePoint Webhooks will be supported for asynchorinious events, like for ItemAdded or ItemAttachmentAdded. To be able to subscribe to SharePoint Webhooks, you’ll need to build a service, which will response on the subscribed validation messages and will process the incoming events.

Notice. When this webcast was released SharePoint Webhooks were not yet released. They will be provided for Developer Preview soon with support for list item specific events for lists and libraries. 

Presentation covers following topics:

  • What are Webhooks?
  • Process for subscribing to a SharePoint Webhook
  • Event notifications from SharePoint
  • Demo setup and details on performed steps

Web cast demo shows following details

  • Registration of Azure App used for Webhook
  • Using PostMan to register a Webhook for SharePoint
  • Responding to Webhook validation tokens from WebAPI
  • Processing incoming events from SharePoint
  • Using ngrok to develop SharePoint Webhooks locally in your development environment

What is SharePoint / Office DevPatterns & Practices (PnP) web cast series?PnP logo

SharePoint and Office Dev Patterns & Practices (PnP) webcast 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 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.

If you have any questions, comments or feedback around PnP program or this blog post, please use the Office 365 Network (SharePoint Developer group).
