Then, click Edit next to Webhook to make your changes. Tip: If you need to add, remove, or modify variables at any point, open your workflow in Workflow Builder. In the example below, if the user, severity, and incident_description were not sent with your webhook request, the workflow would fail. Please note that it's not currently possible to use nested JSON structures in workflow variables. Once you add a variable, you’ll see a preview of the HTTP body so you can make sure the values match up with the JSON outputs in the other service you’re connecting to Slack via your webhook. To create a custom variable, you'll add a key value pair in Workflow Builder as a text-based variable. You can add up to 20 variables to pass data into Slack from another service and include Slack-specific information like display names or email addresses in steps you add to your workflow. Tip: If you're not sure how to configure your webhook, we recommend asking a developer on your team for help or referencing any support documentation provided by the service you’re using, like Postman or Zapier. Any data your webhook sends to Slack can be referenced in subsequent workflow steps by creating variables.

Slack will generate a unique request URL for your workflow once you publish it, and you can configure your webhook to pass information to Slack via the HTTP request body. The external service you choose to create and configure your webhook needs to provide you with the ability to make an HTTP POST request to Slack when certain events occur. For example, you might set up a workflow that posts a message to Slack when there’s a problem with your website or service and an incident has been called to understand and resolve the issues. To trigger a workflow using a webhook, you’ll configure the webhook to start your workflow in Slack when an event you specify occurs in another service.
