Incident Response Workflow - Part 2

This workflow is the second of three. You can find the other workflkows here: Incident Response Workflow - Part 1 Incident Response Workflow - Part 2 Incident Response Workflow - Part 3 We have the following nodes in the workflow: Webhook node: This trigger node listens to the event when the Acknowledge button is clicked. PagerDuty node: This node changes the status of the incident report from 'Triggered' to 'Acknowledged' in PagerDuty. Mattermost node: This node publishes a message in the auxiliary channel saying that the status of the incident report has been changed to Acknowledged.

Help me set up the n8n workflow "Incident Response Workflow - Part 2" (https://n8n.io/workflows/354). It uses: Mattermost, PagerDuty. Import the template JSON into my n8n instance, list every credential I need to create, and walk me through testing it.
