Stripe + Slack integration

Plandalf connects them with a native Slack app, not a direct Stripe-to-Slack feed. Payments taken through a Plandalf checkout on your Stripe account can post to a channel through the Slack notifications recipe or a Send Slack Message step. Plandalf can also post failed-automation alerts to Slack. It covers Plandalf invoices, not every charge on the Stripe account.

1. Connect Slack

   In Plandalf open Automation, then Marketplace, and click Connect on Slack. Click Add to Slack, check the workspace named in the top-right of the Slack window, and click Allow. There is no API key. Plandalf shows Slack connected.

2. Open the Slack notifications recipe

   Under Automation, then Templates, open Slack notifications in the Recipes section and check the Slack workspace shown is the one you connected.

3. Switch on the events

   Choose from New purchase, Subscription / invoice paid, Refund and Upsell accepted. For each, pick a Channel such as #sales for purchases and #support for refunds, edit the Message if you like and click Save.

4. Add private channels to the app

   Public channels work at once. For a private channel, open it in Slack, go to its details, choose Integrations and add the Plandalf app, then reopen the channel list in Plandalf.

5. Write a custom message when you need one

   In a sequence, add Slack, Send Slack Message and pick a Channel. In a sequence that starts on Invoice Refunded, use {{trigger.refund_amount_formatted}} for this refund and {{trigger.refunded_total_formatted}} for the total refunded so far.

6. Route failures to Slack

   Under Automation, then My apps, open the Slack connection, switch on Post automation failures to Slack, choose a Failure alert channel and click Save Changes. Failed automation notifications must also be on under Settings, then Notifications.

7. Check it with one real post

   A step test posts a real message to the real channel, so warn the channel first. Test purchases skip automations by default, so confirm the setup with a step test and look at the Events view for each run.

• The recipe and Send Slack Message cover payments and invoices that Plandalf handles. Charges made elsewhere on the same Stripe account do not post.
• The Refund notification posts for every refund, partial ones included. A sequence you build yourself on Invoice Refunded has Full refunds only on by default, so the two behave differently.
• Switching an event off in the Slack recipe deletes its notification sequence. The recipe's sequences are managed by Plandalf and do not appear in My Sequences.
• A private channel is missing from the picker until the Plandalf app has been added to it. Step output with not_in_channel or channel_not_found points to the same cause.
• If Slack refuses a message, the step still finishes and its output shows status: failed with Slack's error code, such as is_archived or invalid_auth. Read the run in the Events view.
• A workspace that restricts apps needs a Slack admin to approve Plandalf before it can connect.

Does Stripe integrate with Slack?

Plandalf links them. Stripe handles the payment in a Plandalf checkout, and Plandalf posts the purchase, renewal, upsell or refund to a Slack channel. If you want Stripe's own Slack alerts for charges outside Plandalf, check Stripe's integrations list.

How do I connect Stripe sales to Slack?

Connect Stripe to Plandalf and publish a checkout, connect Slack from Automation, then Marketplace, and switch on events in the Slack notifications recipe under Templates. Each event takes its own channel.

Can I send Stripe refunds to Slack?

Yes. The Refund event in the recipe posts when a refund succeeds in Stripe, including from the Stripe dashboard, with the amount refunded in the message.

Can Slack tell me when an automation fails?

Yes. Switch on Post automation failures to Slack on the Slack connection and pick a channel. Alerts follow your Failed automation notifications setting and go out at most once every 15 minutes per sequence.
