Steps
Steps marked “human step” are ones only you can do: verapli never signs in, submits, pays or accepts terms for you.
Sign in or create a Churnkey account
Sign in to Churnkey. If you have no account yet, you create it yourself; verapli does not create accounts.
Where: https://app.churnkey.co/
Connect your billing provider
Connect Stripe or another supported billing provider so Churnkey can pause, discount or cancel subscriptions.
Copy App ID and API key
In Settings > Organization > Cancel Flow API Keys copy the App ID (public) and API Key (server only; used to compute the HMAC-SHA256 authHash of the customer ID). Or run stripe projects add churnkey/retention.
