Auto-create Stripe customers from your backend
User signs up in your app? A webhook fires, and Notis creates them as a customer in Stripe automatically.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create Customer
Creates a new customer in stripe, required for creating charges or subscriptions; an email is highly recommended for customer communications.
Why this helps
Manual customer creation in Stripe after signup creates delays and increases the risk of forgotten accounts.
- Auto-create customers instantly after signup
- Eliminate manual account setup
- Enable frictionless onboarding
- Keep customer data synchronized
Setup
Build it in a few focused steps.
- 1Connect Stripe to Notis.
- 2Create an automation: name it 'Webhook Customer Create', use this prompt: 'When you receive a webhook with a new customer/user signup, create that person as a customer in Stripe automatically', choose 'Incoming Webhook'.
- 3Notis gives you a webhook URL to add to your backend.
- 4In your app, send a POST request to that URL when users sign up, including name and email.
- 5Test by triggering a signup in your app and verifying the customer appears in Stripe.
Questions about this workflow
What data should I send in the webhook?
Send at least name and email. You can include company, phone, address, or any customer metadata.
Does this work for existing customers in my app?
Yes, you can bulk-sync existing customers by sending webhook requests for each one.
What if the customer already exists in Stripe?
Notis will check first and skip if they're already there, or update them if you configure it that way.

Supported Triggers and Actions
Notis builds workflows that link Slack to Stripe. A trigger fires from one place; an action lands in another.
Slack triggers
Stripe actions

Cancels a customer's active stripe subscription at the end of the current billing period, with options to invoice immediately for metered usage and prorate charges for unused time.
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Confirm payment intent
Confirms a stripe paymentintent to finalize a payment; a `return url` is necessary if the payment method requires customer redirection.
