The short answer
In Connections → Revenue, tap Connect Stripe (read-only) or paste a restricted key that starts with rk_. Cosmo then sees MRR, new customers and churn, so campaigns are judged on revenue, not clicks. Never paste a secret sk_ key. Cosmo refuses it anyway.
| Account | What Cosmo does with it | Access |
|---|---|---|
| Stripe | Sees MRR, new customers and churn, so every campaign is judged on revenue, not clicks. | Read-only |
Go to Connections → Revenue.
Option 1: Connect Stripe
Sign in with Stripe and approve read-only access. This button only appears when it's set up on the server.
Option 2: a restricted key
- In Stripe, go to Developers → API keys → Create restricted key.
- Give it Read on Customers, Subscriptions, Charges, Products and Prices.
- Paste the key. It starts with rk_live_ or rk_test_.
Cosmo checks the key with a read-only call before saving it. Secret keys (sk_) and publishable keys (pk_) are refused.
To remove Stripe, tap Disconnect on the Revenue card.
