Send this to your assistant

Create a ClickRuntime automation: when a Stripe subscription is cancelled, Slack me the customer's name, email and plan.

Paste it into your assistant. It tells you what it will send or change before it runs live.

Why use it

Why teams use this automation

A subscription business loses a customer on a Tuesday afternoon and finds out in the monthly revenue review. By then the account manager who could have called, offered a discount or asked what went wrong has no context left, and the customer has already moved to a competitor. For a company with a few hundred high-value accounts, a single quiet cancellation can be a four-figure annual loss.

The moment Stripe sends a customer.subscription.deleted event, ClickRuntime looks up the customer to get their name, email and plan, then posts a message to your Slack channel. The people who own retention hear about it while the customer is still reachable and the decision is fresh.

It works well for B2B teams with a handful of key accounts, and for founders who still reach out personally to people who leave.

What you get out of it

A save attempt becomes possible
Calling within hours of a cancellation gives you a real chance at winning someone back, or at least learning the reason. A week later the customer has usually settled on an alternative.
High-value losses are never a surprise
The alert includes the plan, so a cancelled enterprise subscription stands out from a monthly starter plan. Leadership learns about big losses the same day rather than at quarter end.
Customer success knows who to talk to
The message names the customer and links to their record, so the account owner can pull up their history and conversations immediately without searching through Stripe. They can open the customer record and start the conversation with context already in hand.
Patterns appear in the channel itself
Three cancellations in one afternoon after a deployment or price change is a signal you can see by scrolling Slack. The feed acts as an early warning for product or billing problems.
Refund and access cleanup happens on time
Knowing a subscription ended promptly lets you remove seats, close accounts or handle pro-rata refunds before the customer has to ask for it, which keeps goodwill intact. Handling the offboarding quickly also shows customers you take their account seriously.

Build your own

Need it to work differently?

This template is a starting point. Copy the prompt and change it, or describe a different automation from scratch, with your own conditions, more apps or an AI step. Your assistant writes it, tests it and runs it on ClickRuntime.

Your own rules
Conditions, thresholds, filters and exceptions, written the way you'd explain them to a colleague.
Any number of apps
One automation can read from one app and update several others. Over 248 apps are ready, and anything with an API works too.
AI where it helps
Summaries, classification, extraction and drafts use ClickRuntime's built-in AI, with no extra key.
On a schedule or on each event
Runs as often as every 5 minutes, or the moment an app sends an event, and keeps track of what it already handled.

Changes you can ask for

Act only on the items that match your own rules, and skip the rest
Add an AI step, for example to summarize, sort or draft a reply
Add another app, for example also send it to Slack
Combine it with other Stripe steps into one automation

Under the hood

The code that runs this automation

This is the Python script that runs each time the automation starts. Your AI assistant writes it for you when you send the prompt, and you allow each step in your assistant. To change how the automation works, describe the change to your assistant and it updates the script for you. For every function it can use, see the script reference.

cancellation_churn_alert.pyexample

import stripe
from clickruntime import on_event, credentials, notify, verify

@on_event
def handle(event):
    if not verify.stripe(event.body, event.header("Stripe-Signature"), credentials.secret("STRIPE_WEBHOOK_SECRET")):
        return {"ignored": "bad signature"}
    if event.json["type"] != "customer.subscription.deleted":
        return {"ignored": event.json["type"]}
    sub = event.json["data"]["object"]
    stripe.api_key = credentials.secret("STRIPE_API_KEY")
    customer = stripe.Customer.retrieve(sub["customer"])
    price = sub["items"]["data"][0]["price"]
    plan = price.get("nickname") or stripe.Product.retrieve(price["product"]).name
    notify.slack(f"Subscription cancelled: {customer.name or 'no name'} ({customer.email}) · {plan}", channel="#revenue")
    return {"customer": sub["customer"]}

FAQ

Common questions

Does it fire when a customer only schedules a cancellation at period end?

A scheduled cancellation changes the subscription's cancel_at_period_end flag and arrives as an update event, while the deleted event fires when the subscription actually ends. You can choose to be alerted at either point, or both.

Will trial users who never paid trigger an alert?

They can, because a canceled trial is also a deleted subscription. If you only care about paying customers, add a condition on the plan or on whether an invoice was paid, and trial cancellations are skipped.

Which Slack channel does it post to, and can it tag someone?

You pick the channel when you connect Slack. The message can mention a specific person or group, such as the account owner, if you tell your assistant who should be tagged for which plans. Ask for a different channel per plan if you like.

What permissions does it need?

read. Nothing else in your accounts is used.

Does it need AI?

No. It runs without AI, so it doesn't use your plan's AI allowance.

How many runs does it use?

One run for each event the app sends.

Can I change how it works?

Yes. Describe the change to your AI assistant, for example a different schedule, channel or filter. It updates the automation, tests it and tells you what changed.
