  title: Xendit Balance Payment Requests API
  description: 'Xendit is a payments infrastructure provider for Southeast Asia. This OpenAPI document describes a representative, high-fidelity subset of the public Xendit REST API grounded in the developer documentation at https://docs.xendit.co - the unified Payments API (Payment Requests and Payment Tokens), hosted Invoices, Payouts / disbursements, Balance, Transactions, Customers, and Refunds. All requests are authenticated with a secret API key passed over HTTP Basic (the API key is the username, the password is left empty) against the base host https://api.xendit.co.

    Scope note: The newer Payments API resources (payment_requests, payment_tokens, payouts v3, refunds) require an `api-version` header. Some read/update operations here (get transaction by ID, get/update customer, get refund by ID, cancel payout, expire invoice) follow Xendit''s documented resource conventions but were not each individually confirmed against a published reference page at authoring time; they are modeled as representative and flagged in review.yml. Xendit does not publish a machine -readable OpenAPI file at a single canonical public URL; this document was authored by API Evangelist from the human documentation.'
