This guide explains how to integrate Assertiv with Slack using SAML. When this set up is complete, users will be able to log into Slack using their Assertiv account.
To use SAML with Slack, you must be on the Slack Plus plan or higher.
Create Slack app in Assertiv
Log into your Assertiv Organization (https://<your-org>.assertiv.com) as an Admin user and select the App Config dashboard tile.
Select the plus () button to create a new App config.
Search for the Slack application and select the Slack icon.
You will be prompted for some information on the following page.
Slack Service Name: This is the name of the application how you would like it to appear in Assertiv. Make this a descriptive name that your users will understand. E.g "Corporate Slack"
Signing Certificate: The certificate is used to create a trust between Assertiv and your Slack account. For advanced users, if you have created a certificate you wish to use, select it here. Otherwise (or if you are unsure) you can select "-- Generate New Signing Certificate --".
Slack Subdomain URL Prefix: When you create a slack account, you are given a specialized URL for your organization (e.g. https://acme.slack.com). Enter the first section of the URL hostname. E.g. for https://acme.slack.com, enter acme.
