Products

Create a product

Creates a new product. Set frequencyInDays to define the billing cycle:

Omit or set to null → one-time product
Set to 30 → monthly subscription, 365 → yearly, etc.

Custom pricing (`isCustomPrice: true`)

When enabled, the product has no fixed price. Instead, you pass priceCents and currency each time you create a payment or subscription.

One-time + custom price — ideal for variable amounts:

Wallet top-ups (user chooses how much to add)
Donations or tips
Invoices with different totals

Subscription + custom price — ideal when the price is decided at checkout:

Tiered pricing (e.g. user picks a seat count or plan level)
Negotiated rates set per-customer

When isCustomPrice is true, do not set priceCents or currency on the product — they are provided per-payment via POST /api/payment/create or POST /api/subscription/create.

Platform: Only WEB and INVOICE are supported via the API.
