Remember, a webhook is a mechanism we can use to call a service or function when a specific event occurs on Tableau Server. Our Python script will be the glue between the different components mentioned in the introduction. Architecture and FlowĮnough about introductions and preparations on to the actual substance. Slack app authentication is slightly more complicated, so if these concepts are new to you, it's a good idea to read up and then set up the app and grab the token.Īside from authentication, it's worth checking the usage section of the documentation to set up the Python virtual environment and the further pre-requisites. The bulk of that is related to the authentication to the two platforms we're working with: Tableau Server and Slack.įor Tableau Server, we'll be using Personal Access Tokens, which are currently the preferred way of authenticating to the Tableau Server REST API, and are easy to set up.Īs for Slack, we've set up an app that uses a bot token to authenticate. There are a few aspects of this project that do require some preparation. We'll refer to that repository from time to time. There are improvements to work on, but the concepts and functionality are all there and available on GitHub.

The notification message should contain a link to the workbook, as well as its thumbnail. The resulting application is based on the premise of posting a notification to Slack when a new workbook is published to Tableau Server.

In an effort to learn about a few concepts relevant to Tableau Server and automation, we're going to build the following: a Python script that uses Tableau Server's REST API, webhooks and a library called HTTPServer, to post to Slack.
