How do I find my Subdomain and API Key?

Your subdomain is the first part of your Recurly portal URL (e.g., if you log in at `myproject.recurly.com`, your subdomain is `myproject`). To get your API Key, navigate inside Recurly to Integrations > API Credentials and generate or copy your 'Private API Key'.

Can it accidentally charge my customers?

While the server can manage subscriptions (e.g., setting up a customer with a plan), it strictly follows the billing logic predefined in your Recurly catalog settings. It doesn't bypass credit card validation or execute arbitrary charges directly without a plan context.

Does cancelling a subscription remove the account entirely?

No, using `cancel_subscription` stops future renewals for that specific plan item instance. The underlying user billing account remains intact and can hold other valid subscriptions or past invoices.
