What Sumly reads

  • Every customer's subscriptions, priced by their latest payment
  • Payments without tax and less the store's commission
  • Each purchase, renewal, cancellation and refund the moment it happens, by webhook

Good to know

  • RevenueCat has no list of every subscription, so the full read runs when you connect and then once a day; the webhook fills in between.
  • Only production events count, never sandbox ones.

Connect RevenueCat in a few minutes

  1. 1In RevenueCat: Project settings → API keys → New secret API key, version V2.
  2. 2Read only: Customer information (customers, subscriptions, purchases) and Charts & metrics → Overview. The Project ID is in the address bar after /projects/.
  3. 3After connecting, add the webhook it shows under Integrations → Webhooks, so payments arrive as they happen.
  4. 4To trace purchases to visits, set the attribute sumly_visitor_id to the SDK's visitor id.

Trace each payment to its visit

Set the subscriber attribute sumly_visitor_id to the SDK's visitor id. RevenueCat keeps names starting with $ for itself, so the attribute has no $. How attribution works.

Questions

Can one project have RevenueCat and Stripe?

Yes. A project can take money through several providers, and Sumly adds them up.
