Enabling Integration via Webex Teams and Cisco DNA, SD-Wan, Intersight, Thousand Eyes via Cloud API Gateway
Team messaging that keeps working moving beyond the meeting. With Webex, you get more than just a video conferencing solution. You get a full featured messaging platform to keep your team connected and your work moving even after the meeting ends. One-on-one and group messaging lets you quickly chat with the people you work with every day.
I was really excited to have a unique opportunity to put together a team of my fellow engineers to work on a Collaboration hacking contest within Cisco. This annual event is usually in-person for a day or two in San Jose, making it out of reach for my nomadic desert comrades located in Arizona. This year, however, remote is the new normal. This unique situation made it possible for my ragtag band of misfits to participate in events regardless of our geography. Doosan forklift price. So we embarked on a mission to enable webhook integration for Webex teams, so that our products can send notifications into Teams, just as they can into email.
- Sign in to Webex Teams for group chat, video calling, and sharing documents with your team. It's all backed by Cisco security and reliability.
- In fact, Webex Teams extends basic WebRTC calling to improve quality of service and adapt to network inconsistencies in order to provide the best quality web conferencing experience possible. Now we are taking this a step further, bringing Webex Meetings to an open source JavaScript SDK.
A cloud native yet cloud agnostic solution
In order to do this we decided to make sure this wasn’t only able to support diverse products, but also, diverse clouds. A cloud native, yet cloud agnostic solution based upon serverless infrastructure supporting standard webhooks and HTTPS Post messages. We decided on Google Cloud platform and Amazon Web Services for our multi cloud endeavor.
The initial idea was actually for a separate use case – I have esp8266 modules integrated with Teams for the use case of being notified when my garage door is opened/closed, my bearded dragon’s cage is hot, etc. As these scale in number, if I ever were to change my security bot token or room ID, I would have to go re-flash all of my IoT Sensors to match. So, it creates an operational problem for leveraging Teams as a IoT device receiver or third party integrator.
Enable cloud as an API gateway
Angels sketch. The idea was to enable cloud as an API gateway to accept requests, do advanced security checks, and decouple the Webex Teams security and context information from what is flashed onto the sensors to better manage the lifecycle. But extending this to webbooks was a natural evolution that seemed to have the most immediate impact to customers. When Demo’ing some of our cloud technologies (Intersight, Meraki), customers saw that notifications can go to webhook or email, and naturally inquired about their Webex Teams integration.
By enabling the webhook capability, we immediately added support for all of our product sets that support webhooks to integrate with Webex Teams. And do so without requiring any change on either the product, or Webex Teams. We did want to have native “handlers” in the code to handle differences in webhook formatting between different products. For our project we created handlers for Cisco DNA Center and Meraki. We had started work on Thousand Eyes but didn’t have the lab instance able to send webhooks at the time we finished the project. The amount of effort to create and modify a handler is as simple as 20 minutes worth of effort ensuring that the JSON fields that you care about, are included in what is sent to Teams.

Of note, while the code should have been very consistent between solutions, there is a difference in how Google integrates their API with their cloud functions compared to AWS. The API gateway on GCP has been out for a while, but right now integration of the API gateway on Google for cloud functions is in Beta and does require a bit more lift to setup. I expect this will normalize as it is brought to market. Chimpget. I also want to caveat that by noting I was seeking a functional product, closer integration with GCP teams probably would have helped with how I managed some error handling in Cloud Functions to make it integrate with API GW.
