List Whop payment methods from an incoming webhook
When a system event sends Notis a webhook, it lists the stored payment methods for the member or company involved and reports them to Slack. Billing triage starts with the facts already in hand.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
List Payment Methods
Tool to retrieve a paginated list of payment methods for a member or company. Use when you need to view stored payment information such as cards, bank accounts, or digital wallets. Either member_id or company_id must be provided.
Why this helps
A charge fails and diagnosing it means logging into Whop to check what payment methods the member even has on file.
- Starts billing triage with the payment details already gathered
- Lets any billing system pull payment methods automatically
- Keeps the diagnosis in Slack instead of the dashboard
Setup
Build it in a few focused steps.
- 1In the portal, connect Slack and Whop to Notis.
- 2Open your portal link, go to Automations, and create a New Automation.
- 3Write: 'When this webhook fires with a member, list their Whop payment methods and post them to Slack.'
- 4Choose the incoming webhook trigger, copy the URL, and pick the reporting channel.
- 5Send a test request with a real member and confirm the payment methods return.
Questions about this workflow
Do I pass a member or a company?
Either works. Notis lists payment methods when your webhook provides a member id or a company id.
Does it show full card numbers?
No. Whop returns stored payment method details, not full card data, so you see the method without exposing sensitive numbers.
