Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.
wavepay_registerRegister a WavePay merchant account. Returns a live merchant key (key) and a test-mode key (testKey) once — save both; only their hashes are stored. Free tier: 25 payments per 30 days; test mode is uncapped and never reaches a provider.
wavepay_providersList the payment rails this deployment can take — PayNow (EcoCash, OneMoney, InnBucks, Telecash, O'mari, ZimSwitch, cards) and PayPal.
wavepay_pricingLive plans and prices for a product, per rail, with the active promotion.
wavepay_checkoutStart a checkout for a product/plan on a rail; returns the hosted checkoutUrl to hand the buyer.
wavepay_checkout_statusPoll a payment by reference: pending | collected | expired.
wavepay_featuresWhich flagged capabilities (refunds, recurring, bnpl, card_tokens, paypal_billing, disputes) this deployment has switched on for live money. Test-mode keys can use every one.
wavepay_subscribeOpen a subscription for a customer (needs a merchant key; a mk_test_ key previews it with fake money). collection=automatic charges a saved card or PayPal subscription; invoice_and_remind (default, and the only mode for mobile wallets) sends a payment request each period. Returns
wavepay_bnplBuy now, pay later: take a deposit now and collect the rest from the buyer's card on a schedule until the total is paid. Cards only (provider paynow or paypal); prepaid and virtual cards are refused. Needs a merchant key; mk_test_ previews it.
wavepay_refundRefund a settled payment through its provider (PayPal; test payments with a test key). PayNow documents no refund API, so a PayNow payment is refused with REFUND_UNSUPPORTED rather than recorded as refunded. Needs a merchant key.
wavepay_test_billing_runTest mode only (mk_test_ key): run the billing engine as if advanceDays had passed, so renewals, instalments and dunning can be exercised without waiting.
wavepay_catalogMerchant self-service catalog — the sites, plans, prices and coupons your merchant key can see. Requires the x-wavepay-service-key header carrying an mk_live_… or mk_test_… key.
