Slack integration

Bring ServiceNow approvals, notifications and major-incident swarming into Slack in real time using the Slack spoke and Flow Designer.

• ServiceNow: admin, IntegrationHub, and the Slack spoke from the Store.
• Slack: a workspace admin to install/approve the app and grant scopes.

• At api.slack.com/apps → Create New App, add Bot Token Scopes: chat:write, channels:manage, commands, users:read.
• Install to the workspace and copy the Bot User OAuth Token (xoxb-...).

• Store the bot token as an API Key/OAuth credential and attach it to the Slack spoke's Connection alias (base https://slack.com/api).

• Build a flow on incident create where priority=1.
• Add Slack → Post Message to your ops channel with the incident number, short description and a link back.

• Post an interactive message with Approve/Reject buttons (Block Kit) for a change approval.
• Set the Slack app's Interactivity Request URL to a ServiceNow Scripted REST API that records the decision on the approval record.

// Scripted REST (Slack interactivity) - pseudocode
var payload = JSON.parse(request.body.data.payload);
var action = payload.actions[0].value;   // "approve" | "reject"
var sysId = payload.actions[0].action_id;
var ap = new GlideRecord("sysapproval_approver");
if (ap.get(sysId)) { ap.state = (action=="approve") ? "approved" : "rejected"; ap.update(); }

• On P1 declaration, use Slack → Create Channel and invite the assignment group, then post the incident summary.

• Raise a P1 and confirm the message/channel appears instantly.
• not_in_channel: invite the bot to the channel.
• invalid_auth: token revoked/rotated, update the credential.
