Slack

Introduction

The Slack integration posts Dodo Payments events, such as successful payments, subscription changes, and disputes, to a Slack channel you choose. Your team can follow payments and act on disputes from Slack, without checking the dashboard.

The Slack connector turns each Dodo Payments event into a Slack message with a transformation: JavaScript code that runs on the event before delivery. The connector comes with transformation code, so no coding is required to start. You need access to Developer → Webhooks in the Dodo Payments dashboard, and permission to add apps to your Slack workspace.

Getting Started

Open the Webhook Section

In the Dodo Payments dashboard, go to Developer → Webhooks and click Add endpoint.

Add endpoint dialog with the Integration dropdown set to Custom webhook

Select Slack Integration

In Integration, select Slack. The dashboard loads the Slack transformation code and shows setup steps in the How to connect Slack panel.

Create a Slack Webhook URL

In Slack, create an app with an incoming webhook for the channel that should receive notifications:

Open api.slack.com/apps, click Create New App, and choose From scratch.
Name the app, for example Dodo Payments Notifications, pick your workspace, and click Create App.
In the sidebar, open Incoming Webhooks and turn on Activate Incoming Webhooks.
Click Add New Webhook to Workspace, choose the channel, and click Allow.
Copy the Webhook URL, which starts with https://hooks.slack.com/services/.

Paste the Webhook URL

Paste the Slack webhook URL into Endpoint URL. Slack doesn’t need an API key.

Select Events

Subscribed events lists the events the Slack connector supports. If you change the transformation, keep only the events it handles. Slack rejects a request that isn’t a Slack message, so an event that the transformation leaves unchanged fails to deliver.

Customize Transformation Code

Under Transformation code, edit the handler to choose which events post a message and how each message looks. Keep the connector’s code, or start from the examples.

Test and Create

Under Test this code, select an event type and click Simulate. The Result shows the message that Slack would receive. Then click Create endpoint.

Integration Complete!

Dodo Payments now posts each subscribed event to your Slack channel. To post a test message, open the endpoint’s Testing tab, select an event type, and click Send example.

Transformation Code Examples

Each handler replaces webhook.payload with a Slack message and keeps webhook.url, your incoming webhook URL. Dodo Payments amounts are in the smallest currency unit, so the examples divide by 100 and show the currency code. For zero-decimal currencies such as JPY and KRW, use the amount as is.

Basic Payment Notifications

Post a plain-text message when a payment succeeds, fails, or is processing:

payment_notifs.js

function handler(webhook) {
  switch (webhook.eventType) {
    case "payment.succeeded":
      webhook.payload = {
        text: `✅ Payment Successful\nAmount: ${(webhook.payload.data.total_amount / 100).toFixed(2)} ${webhook.payload.data.currency}\nCustomer: ${webhook.payload.data.customer.email}\nPayment ID: ${webhook.payload.data.payment_id}`
      };
      break;
      
    case "payment.failed":
      webhook.payload = {
        text: `❌ Payment Failed\nAmount: ${(webhook.payload.data.total_amount / 100).toFixed(2)} ${webhook.payload.data.currency}\nCustomer: ${webhook.payload.data.customer.email}\nReason: ${webhook.payload.data.error_message || 'Unknown'}`
      };
      break;
      
    case "payment.processing":
      webhook.payload = {
        text: `⏳ Payment Processing\nAmount: ${(webhook.payload.data.total_amount / 100).toFixed(2)} ${webhook.payload.data.currency}\nCustomer: ${webhook.payload.data.customer.email}`
      };
      break;
  }

  return webhook;
}

Rich Subscription Notifications

Post a color-coded message with attachment fields when a subscription becomes active, is cancelled, or renews:

subscription_notifs.js

function handler(webhook) {
  switch (webhook.eventType) {
    case "subscription.active":
      webhook.payload = {
        attachments: [{
          color: "good",
          title: "🎉 Subscription Activated",
          fields: [
            {
              title: "Customer",
              value: webhook.payload.data.customer.email,
              short: true
            },
            {
              title: "Product ID",
              value: webhook.payload.data.product_id,
              short: true
            },
            {
              title: "Amount",
              value: `${(webhook.payload.data.recurring_pre_tax_amount / 100).toFixed(2)} ${webhook.payload.data.currency}/${webhook.payload.data.payment_frequency_interval}`,
              short: true
            },
            {
              title: "Next Billing",
              value: new Date(webhook.payload.data.next_billing_date).toLocaleDateString(),
              short: true
            }
          ],
          footer: "Dodo Payments",
          ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
        }]
      };
      break;
      
    case "subscription.cancelled":
      webhook.payload = {
        attachments: [{
          color: "warning",
          title: "⚠️ Subscription Cancelled",
          fields: [
            {
              title: "Customer",
              value: webhook.payload.data.customer.email,
              short: true
            },
            {
              title: "Product ID",
              value: webhook.payload.data.product_id,
              short: true
            },
            {
              title: "Cancellation Date",
              value: new Date(webhook.payload.data.cancelled_at).toLocaleDateString(),
              short: true
            },
            {
              title: "Cancel at Next Billing",
              value: webhook.payload.data.cancel_at_next_billing_date ? "Yes" : "No",
              short: true
            }
          ],
          footer: "Dodo Payments",
          ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
        }]
      };
      break;
      
    case "subscription.renewed":
      webhook.payload = {
        attachments: [{
          color: "good",
          title: "🔄 Subscription Renewed",
          fields: [
            {
              title: "Customer",
              value: webhook.payload.data.customer.email,
              short: true
            },
            {
              title: "Product ID",
              value: webhook.payload.data.product_id,
              short: true
            },
            {
              title: "Amount",
              value: `${(webhook.payload.data.recurring_pre_tax_amount / 100).toFixed(2)} ${webhook.payload.data.currency}`,
              short: true
            },
            {
              title: "Next Billing",
              value: new Date(webhook.payload.data.next_billing_date).toLocaleDateString(),
              short: true
            }
          ],
          footer: "Dodo Payments",
          ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
        }]
      };
      break;
  }

  return webhook;
}

Dispute Management Notifications

Post a red message when a dispute opens or is lost, and a green one when it’s won:

dispute_notifs.js

function handler(webhook) {
  switch (webhook.eventType) {
    case "dispute.opened":
      webhook.payload = {
        attachments: [{
          color: "danger",
          title: "🚨 New Dispute Opened",
          fields: [
            {
              title: "Payment ID",
              value: webhook.payload.data.payment_id,
              short: true
            },
            {
              title: "Amount",
              value: `${(webhook.payload.data.amount / 100).toFixed(2)} ${webhook.payload.data.currency}`,
              short: true
            },
            {
              title: "Status",
              value: webhook.payload.data.dispute_status,
              short: true
            },
            {
              title: "Stage",
              value: webhook.payload.data.dispute_stage,
              short: true
            },
            {
              title: "Remarks",
              value: webhook.payload.data.remarks || "No remarks",
              short: false
            }
          ],
          footer: "Dodo Payments - Action Required",
          ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
        }]
      };
      break;
      
    case "dispute.won":
      webhook.payload = {
        attachments: [{
          color: "good",
          title: "✅ Dispute Won",
          fields: [
            {
              title: "Payment ID",
              value: webhook.payload.data.payment_id,
              short: true
            },
            {
              title: "Amount",
              value: `${(webhook.payload.data.amount / 100).toFixed(2)} ${webhook.payload.data.currency}`,
              short: true
            },
            {
              title: "Status",
              value: webhook.payload.data.dispute_status,
              short: true
            },
            {
              title: "Resolution",
              value: "Dispute resolved in your favor",
              short: false
            }
          ],
          footer: "Dodo Payments",
          ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
        }]
      };
      break;
      
    case "dispute.lost":
      webhook.payload = {
        attachments: [{
          color: "danger",
          title: "❌ Dispute Lost",
          fields: [
            {
              title: "Payment ID",
              value: webhook.payload.data.payment_id,
              short: true
            },
            {
              title: "Amount",
              value: `${(webhook.payload.data.amount / 100).toFixed(2)} ${webhook.payload.data.currency}`,

              value: "The disputed amount stays deducted from your balance",
              short: false
            }
          ],
          footer: "Dodo Payments - Review Required",
          ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
        }]
      };
      break;
  }

  return webhook;
}

Comprehensive All-Events Handler

Post a message in the same format for every event type. Events without their own case get a generic message with the event type and time:

all_events_notifs.js

function handler(webhook) {
  const event = webhook.payload.data;
  const timestamp = new Date(webhook.payload.timestamp).toLocaleString();
  
  let color, emoji, title, fields = [];
  
  switch (webhook.eventType) {
    case "payment.succeeded":
      color = "good";
      emoji = "✅";
      title = "Payment Successful";
      fields = [
        { title: "Amount", value: `${(event.total_amount / 100).toFixed(2)} ${event.currency}`, short: true },
        { title: "Customer", value: event.customer.email, short: true },
        { title: "Payment ID", value: event.payment_id, short: true },
        { title: "Method", value: event.payment_method || "Unknown", short: true }
      ];
      break;
      
    case "payment.failed":
      color = "danger";
      emoji = "❌";
      title = "Payment Failed";
      fields = [
        { title: "Amount", value: `${(event.total_amount / 100).toFixed(2)} ${event.currency}`, short: true },
        { title: "Customer", value: event.customer.email, short: true },
        { title: "Reason", value: event.error_message || "Unknown", short: false }
      ];
      break;
      
    case "subscription.active":
      color = "good";
      emoji = "🎉";
      title = "Subscription Activated";
      fields = [
        { title: "Customer", value: event.customer.email, short: true },
        { title: "Product ID", value: event.product_id, short: true },
        { title: "Amount", value: `${(event.recurring_pre_tax_amount / 100).toFixed(2)} ${event.currency}/${event.payment_frequency_interval}`, short: true },
        { title: "Next Billing", value: new Date(event.next_billing_date).toLocaleDateString(), short: true }
      ];
      break;
      
    case "subscription.cancelled":
      color = "warning";
      emoji = "⚠️";
      title = "Subscription Cancelled";
      fields = [
        { title: "Customer", value: event.customer.email, short: true },
        { title: "Product ID", value: event.product_id, short: true },
        { title: "Cancellation Date", value: new Date(event.cancelled_at).toLocaleDateString(), short: true },
        { title: "Cancel at Next Billing", value: event.cancel_at_next_billing_date ? "Yes" : "No", short: true }
      ];
      break;
      
    case "refund.succeeded":
      color = "good";
      emoji = "💰";
      title = "Refund Processed";
      fields = [
        { title: "Amount", value: `${(event.amount / 100).toFixed(2)} ${event.currency || ""}`, short: true },
        { title: "Refund ID", value: event.refund_id, short: true },
        { title: "Payment ID", value: event.payment_id, short: true },
        { title: "Reason", value: event.reason || "Not specified", short: true }
      ];
      break;
      
    case "dispute.opened":
      color = "danger";
      emoji = "🚨";
      title = "New Dispute Opened";
      fields = [
        { title: "Payment ID", value: event.payment_id, short: true },
        { title: "Amount", value: `${(event.amount / 100).toFixed(2)} ${event.currency}`, short: true },
        { title: "Status", value: event.dispute_status, short: true },
        { title: "Stage", value: event.dispute_stage, short: true },
        { title: "Remarks", value: event.remarks || "No remarks", short: false }
      ];
      break;
      
    case "license_key.created":
      color = "good";
      emoji = "🔑";
      title = "License Key Created";
      fields = [
        { title: "License ID", value: event.id, short: true },
        { title: "Product ID", value: event.product_id, short: true },
        { title: "License Key", value: event.key.substring(0, 8) + "****", short: true },
        { title: "Expires", value: event.expires_at ? new Date(event.expires_at).toLocaleDateString() : "Never", short: true }
      ];
      break;
      
    default:
      // Handle any other events with a generic format
      color = "#3aa3e3";
      emoji = "ℹ️";
      title = webhook.eventType.replace(/_/g, ' ').replace(/\b\w/g, l => l.toUpperCase());
      fields = [
        { title: "Event Type", value: webhook.eventType, short: true },
        { title: "Timestamp", value: timestamp, short: true }
      ];
  }
  
  webhook.payload = {
    attachments: [{
      color: color,
      title: `${emoji} ${title}`,
      fields: fields,
      footer: "Dodo Payments",
      ts: Math.floor(new Date(webhook.payload.timestamp).getTime() / 1000)
    }]
  };

  return webhook;
}

Best Practices

Follow these practices to keep Slack notifications useful:

Use message attachments with colors and fields, so each event is clear and easy to act on.
Include key data such as the amount, customer email, and IDs, so your team can find the record quickly.
Match the color to the event type: green (good) for success, red (danger) for disputes or failures, yellow (warning) for cancellations, and blue (#3aa3e3) for informational events.
Add a timestamp (ts), so each message shows when the event occurred.

Handle Sensitive Data: Don’t post sensitive values such as full license keys or personal data to Slack. Truncate or mask them, as the license key field in the all-events example does.

Troubleshooting

Notifications Not Appearing in Slack

Check that the Slack webhook URL is correct and that its Slack app is still installed.
Check that the transformation code is valid JavaScript.
Check that the subscribed events are occurring. To send one, use Send example on the endpoint’s Testing tab.
Check that your Slack app has Incoming Webhooks turned on and can post to the channel.

Transformation Errors

Open the Logs tab in Developer → Webhooks and check the failed delivery’s response.
Check that the payload fields your code reads match the event payload for that event type.
Test your code with Simulate and a sample payload.
Check that each field your code reads is present. Optional fields, such as error_message, can be null.

Missing Event Types

Check that the event is selected in Subscribed events. To change the selection, open the endpoint and click Edit.
Check that the Slack connector supports the event. Subscribed events lists only the events the connector supports.
Check that your transformation has a case for the event. The examples leave other events unchanged, and Slack rejects them.
