Payments
Payments is how your app gets paid: its connection to Stripe, the plans a customer can be on, and the products they can buy. Choose how each one is sold, what credits it grants, and what a buyer receives.
The walk
The room
Open Payments to see how your app gets paid: its connection to Stripe, its plans and its products.

Plans
Open Plans to see what a customer can be on and how each plan is sold.

Choose Add a plan and name it: four questions, and nothing else on your payments setup moves.

Say what it grants each period, and what happens to what is left when the next one is paid.

Review says what a customer pays for, what they get, and what happens if they stop — before the plan exists.

Open a plan you already have to change how it's sold: a Stripe Payment Link, a relay, or not sold at all.

Set Credits each period to grant credits with every paid period, and choose what happens to credits left unused.

Choose Save plans: every plan on this page is saved together.

Products
Open Products to see the one-off things customers can buy, like a pack of credits.

Choose Add a product to add one in five questions — what it is, how it is sold, and what the buyer gets.

Review names where receipts land and what a buyer keeps, with the line your app writes to show what they bought.

Open a product you already sell to change how it's sold and what the buyer receives: a file, a link, or credits.

What it refuses and why
These are the console's own words when a change can't be saved or a request can't go through.
LIVE link — this environment needs the test-mode one (path starts with test_)
Development is a rehearsal, so it takes Stripe's test-mode links; live links belong to production.
payment links start with https://buy.stripe.com/ — this is something else
A plan is sold through the Payment Link Stripe gives you: one address that stays the same for every buyer.
a whole number of credits each period, or empty
A plan's allowance is a whole number of credits, granted in full each paid period.
