  summary: Partner-facing API for boarding and managing sub-merchants and their acquirer connections.
  description: "The Partner API lets you (a Fat Zebra partner) create and manage your own\nmerchants, board them onto acquirers, and manage the resulting acquirer\nconnections. You pick an acquirer (your bank relationship); Fat Zebra\ndecides which processors carry it.\n\n## Base URL\n\n```\nhttps://gateway.pmnts.io/v2/partners\n```\n\nAll paths below are relative to that base. Sandbox and staging hosts are in\nthe server list; pick the one for your environment.\n\n## Auth\n\nHTTP Basic. Send your reseller **username** as the Basic username and your\nreseller API **token** as the Basic password\n(`Authorization: Basic <base64(username:token)>`). Every endpoint requires\nit.\n\n## Boarding is synchronous\n\nBoarding a merchant onto an acquirer is synchronous: an acquirer connection\nexists only once it is boarded, so it is always live. A board that can't\ncomplete is reported inline as the POST's `422` error response.\n\n## Envelopes\n\n* **Single resource** — returned as the resource itself, no wrapper.\n* **List** — `{ \"items\": [...], \"next_cursor\": <string|null> }`. A `null`\n  `next_cursor` means the last page; otherwise pass its value as\n  `starting_after` to fetch the next page. List query params are `limit`\n  (default 25, max 100) and `starting_after=<id>`.\n* **Error** — `{ \"error\": { \"type\", \"message\", \"fields\", \"request_id\" } }`.\n  `type` is the coarse class; the specific reason lives in `fields`, keyed by\n  a processor-agnostic field name (e.g. `mid`, `tid`, `currencies`) so you\n  never read a switch's native field paths. `type` values and statuses:\n  `authentication_error` (401), `not_found` (404), `conflict` (409),\n  `validation_error` (422 — something the caller can fix, including a\n  processor rejecting a field like the MID/TID), `processor_error` (422 —\n  an unactionable upstream failure: a processor was unreachable, busy, or\n  rejected us for a reason the caller can't fix; retry or escalate,\n  `fields` is empty).\n\nTimestamps are ISO 8601 UTC. Merchants and partners are addressed by their\n`username`. An acquirer connection's `id` is a derived merchant+acquirer\nvirtual id of the form `<merchant-id>-ACQ-<ACQUIRER-CODE>` (e.g.\n`042-ACQ-NAB`) — not a stored id. Wallets and users carry a stable generated\nid of the form `<owner-id>-<TYPE>-<random>` (e.g. `042-WAL-9f3k2m8q`).\nAcquirers are slug codes (e.g. `nab`, `cba`, `anz`).\n"
