  title: Omise (Opn Payments) Account Disputes API
  description: 'Omise, now Opn Payments (part of Opn), is an online payment gateway for Thailand, Japan, and Singapore. This OpenAPI document describes a representative, grounded subset of the public REST API. The core API is served from https://api.omise.co and authenticated with a secret key via HTTP Basic (the key is the username, the password is empty). Raw card data is tokenized on a separate PCI-scoped vault host, https://vault.omise.co, authenticated with the public key. API behavior is pinned with the optional `Omise-Version` header. All monetary amounts are integers in the smallest unit of the currency (for example satang for THB, yen for JPY).

    Scope note: paths, methods, and object identifiers here are grounded in the published Omise documentation (docs.omise.co). Request and response schemas are modeled as a solid representative subset rather than a byte-for-byte mirror of every field; verify exact payloads against the live docs.'
