API reference and playground

Opens a hosted checkout for one order. This is the starting point for most integrations — you create a session, then send the shopper to the returned URL to pay.

Reads back a session and its payment state. Use it to confirm what actually happened after the shopper returns, rather than trusting the redirect alone.

Lists recent transactions with paging. The backbone of any reconciliation or admin screen you build.

Full detail for one transaction — card metadata, provider, fees, refund and capture totals. Use it when a shopper disputes a charge.

Kicks off a transaction export batch. Use it for finance reporting instead of paging the list endpoint.

Lists a customer's saved cards so you can offer one-tap repeat payments. Needs a Kashier-Hash keyed with your Payment API Key.

Lists banks offering installments for an amount, with their card BIN ranges. Call it first to build the bank picker at checkout.

Lists the concrete plans (tenor, interest, admin fee) for one bank. Call it once the shopper picks a bank or you detect their card BIN.

Lists reusable payment links. Use it for a dashboard of the links your team has shared.

Lists saved customers. Use it to attach repeat orders and saved cards to a known shopper.

Lists payment requests (invoices) you have issued. Use it to chase or reconcile unpaid invoices.

Lists your hosted storefront pages. Use it when you sell without building a checkout of your own.

Returns the payout accounts on the merchant. Read this before creating a transfer so you know where money can land.

Lists outgoing payouts with status. Use it to reconcile what you have actually paid out.

Full detail and status history for one payout. Use it to answer "where is my money" questions.

Lists recurring payout schedules. Use it for automated supplier or payroll runs.

Lists bulk payout batches. Use it when paying many beneficiaries at once.

Quotes the fee for a prospective payout before you send it. Use it to decide the method or pass the cost on.

Reference list of supported banks with their codes. Use it to populate bank dropdowns rather than hard-coding.

Reference list of cities. Use it for address forms and payout beneficiary details.

Describes every payment method and the fields each one needs. Use it to render method-specific forms dynamically.

The payment methods enabled on your account specifically. Use it to show only what this merchant can actually accept.

Installment banks enabled for your merchant. The account-scoped counterpart to the general installments list.

Overview of your balance accounts and available funds. Use it for a wallet or balance screen.

The default destination for settlements. Confirm this before changing payout details.

Lists settlement windows — the batches Kashier pays you in. Use it to match a bank deposit to its transactions.

Lists transactions inside settlements, with fees and net amounts. The detail behind each deposit.

Lists your catalogue products. Use it when building payment links or pages from a catalogue.

Lists product categories. Use it to organise a storefront.

Lists bulk batches for mass link or invoice creation. Requires a currency.

Calculates the fee on a given amount before you charge. Use it to show the shopper or absorb the cost knowingly.

Lists POS terminals on the account. Use it to route in-person payments to the right device.

Lists branches that own POS terminals. Use it for per-branch reporting.

Quotes what you would receive if today's eligible sales were settled early, and what the instant settlement fee would be — without committing to anything. Call it to show the merchant the net amount before they agree. The transaction ids below are documentation examples, so on a live account expect "Reachable" rather than a real quote; pull real ones from the eligible-transactions endpoint first.
