SLACK_MESSAGE_JSONInform your retention team when a customer schedules or completes a cancellation. Separating the request date from the end of access helps the team respond without implying that service has already stopped.
Use the effective cancellation date from your subscription system. Quote the customer’s reason briefly and neutrally, and omit it if unavailable. Distinguish recurring revenue impact from an immediate refund.
Included variants: scheduled, ended. Switch variants in the editor; all versions stay on this page.
Post from your subscription lifecycle event. The account link does not reactivate a subscription, issue a refund, or contact the customer; those actions need your billing workflow.
To post this JSON, create a Slack app with an incoming webhook for your channel, or use chat.postMessage with the appropriate bot token and permissions. Keep credentials on your server.
For buttons, enable Interactivity and handle Slack’s interaction requests, including URL buttons. Acknowledge requests promptly. This preview does not execute actions, authorize users, or save decisions.
Use the top-level fallback text for notifications and accessibility. Test your final payload in Slack; local validation covers the declared subset, and visual details vary by client.
