Overview:
As I have been learning more about leveraging PowerShell and APIs, I decided to work on some fun side projects to put what I learned into action. While I am still quite new to the APIs and Teams webhooks, this was a fun challenge, and I will be releasing a few more after this initial post, which I will link to this article. All source code can be found on my GitHub
At a high level, these scripts will search for data from an API endpoint or endpoints, randomize the information, post date, and text values, then post to a Teams channel of your choosing using Webhooks.
Send-Purr
An image is randomly selected from a random cat subreddit. Cat facts are pulled from the catfact.ninja API. When the r/Chonkers subreddit is used, the Teams post will be formatted to accommodate the chonkers size.
WARNING: Various filters are in place to try and prevent any inappropriate images from being sent.
Initial Setup & Running
- Teams Channel > Connectors > Incoming Webhook
- Give the Webhook a name & logo
- Create the Teams Webhook
- Copy the URI
- The URI is how you tell the script what teams channel to send posts to.
.\Send-Purr.ps1 -TeamsURI 'https://outlook.office.com/webhook/123/123/123/.....'
Using the defined webhooks connector URI a random cat fact and image are sent to the webhooks Teams channel.
No output is displayed in the console. Using the -Verbose option will give you a basic display output
Help
Help info and a list of parameters can be found by running Get-Help .\Send-Purr.ps1, such as:
Get-Help .\Send-Purr.ps1
Get-Help .\Send-Purr.ps1 -Full
