OnlineNIC Reseller API
The OnlineNIC Reseller API (build 4.0.9) gives partners programmatic control of the OnlineNIC product catalogue. Twenty-six domain commands cover availability checking, registration, renewal, information, status and DNS updates, contact objects, registrar transfer in and out, EPP auth codes, private nameservers, Whois verification and ID Shield registrant privacy. Seventeen SSL commands cover CSR parsing, approver-email discovery, ordering, renewal, price and product lookup, order query and listing, domain-control validation, reissue, cancellation with refund, certificate retrieval and revocation. The surface is RPC over HTTPS — two PHP endpoints with a `command` query parameter, POST only — and every response is HTTP 200 carrying a JSON envelope with an integer status code. Authentication is an API key plus a per-request MD5 token over the reseller id, password digest, timestamp and command name, with an optional source-IP allowlist. The reference is published as a PDF; there is no OpenAPI, AsyncAPI, GraphQL SDL or Postman collection.
