Do I write amounts in cents?
Either way works. The step takes 4999 or 49.99 and reads both correctly, so a Currency field can usually be mapped straight in without converting anything. A whole number is still read as the smallest unit, which keeps every automation written before this behaving exactly as it did. Zero-decimal currencies like yen have no minor unit at all, so a decimal amount in one of those is refused rather than quietly rounded.
What kind of Stripe key should I use?
A restricted key with read access is enough for importing and is much safer to paste into another system than a full secret key. If you also want the payment-link and customer-creation steps, the key needs permission to write those specific resources. Give it the narrowest set that covers what you actually use, and nothing else.
Does it keep up with Stripe automatically?
It can. Importing again updates the same table: new customers, subscriptions, invoices or payments are added and changed ones updated, matched on their Stripe IDs, and Keep in sync does that hourly or daily. The import only reads, so nothing is written back, and something deleted in Stripe stays here rather than vanishing from last month's figures. If you need to react within seconds of a payment, that is a webhook problem rather than an import one.
Which resources can I bring across?
Customers, subscriptions, invoices and payments, each imported separately so you can take only what you need. That set is fixed by what the Stripe API exposes cleanly rather than chosen arbitrarily. Customers are usually the one to import first, because they are the records everything else links to and the Stripe ID on them is what makes later joins reliable.
Does this work right now?
Yes. Stripe is one of the connectors where you supply your own credentials rather than depending on an application we registered with the vendor, so there is nothing pending at our end and nothing to wait for. Paste a key and the resource list appears immediately.
