Connect Stripe to MagicBell to receive events and trigger workflows. This guide uses the MagicBell CLI.

Add the Stripe integration

Save your Stripe webhook signing secret in MagicBell. See Stripe webhooks.

magicbell integration save_stripe \
  --data '{"webhook_signing_secret":"whsec_xxx"}'

Copy the ID from the response and use it to build your webhook URL:

https://api.magicbell.com/v2/integrations/stripe/webhooks/incoming/{id}

Setup the webhook

Add a workflow

Create a workflow that triggers automatically when Stripe sends this event. Use liquid templates to access fields in your workflow.

Workflow key

Use this key to trigger the workflow when Stripe sends a customer.subscription.updated:

integration.stripe.customer.subscription.updated

Example workflow

Notify customer when their subscription plan changes.

{
  "key": "integration.stripe.customer.subscription.updated",
  "steps": [
    {
      "command": "broadcast",
      "input": {
        "content": "Your subscription has been updated. The changes will take effect on your next billing cycle.",
        "recipients": [
          {
            "external_id": "{{payload.data.object.customer}}"
          }
        ],
        "title": "Subscription updated"
      }
    }
  ]
}

Save with the CLI

Use the MagicBell CLI to save this workflow to your project. You can also use the Workflows API endpoint instead.

magicbell workflow save \
  --data '{"key":"integration.stripe.customer.subscription.updated","steps":[{"command":"broadcast","input":{"content":"Your subscription has been updated. The changes will take effect on your next billing cycle.","recipients":[{"external_id":"{{payload.data.object.customer}}"}],"title":"Subscription updated"}}]}'

Test the workflow

Use the Stripe CLI to trigger test events and verify your workflow executes correctly.

1. Trigger a test event

Use the Stripe CLI to send a test event:

stripe trigger customer.subscription.updated

2. Verify the workflow ran

Check that MagicBell received the event and executed the workflow:

magicbell workflow list_runs --workflow_key integration.stripe.customer.subscription.updated

3. Debug issues

If the workflow failed or you need more details, fetch the run to see step-by-step execution:

magicbell workflow fetch_run --run_id {run_id}
