Several IDs for one patient | Mantys Eligibility API

identifiers takes up to 5 IDs for one patient. Each payer is searched with every usable ID; the check returns one answer and names the ID that matched. This works on POST /v4/eligibility-checks and POST /v4/appointment-checks.

{
  "tpa_name": "INS026",
  "visit_type": "OUTPATIENT",
  "doctorName": "DHA-P-0000000",
  "identifiers": [
    { "id_type": "CARDNUMBER", "id_value": "1234567890" },
    { "id_type": "EMIRATESID", "id_value": "784-1990-0000001-1" }
  ]
}

Rule	What happens
1 to 5 entries	6 or more, or an empty list, is 422
`identifiers` is the only form	Leaving it out is 422. `id_type`/`id_value` at the top level are not fields and are 422 ("Extra inputs are not permitted")
No duplicates	The same ID twice is 422; Emirates IDs match with or without dashes
`id_type` values	`EMIRATESID`, `CARDNUMBER`, `DHAMEMBERID`, `POLICYNUMBER`; anything else is 422. A member number goes in as CARDNUMBER
Usable on the payer	An ID is used only if the payer accepts its type and, for Emirates IDs, the format is valid. At least one usable ID is enough; if none is usable you get 400 `VALIDATION_FAILED` with one entry per ID (`field`: `identifiers[0].id_type`, `identifiers[1].id_value`, ...)
`extra_args.identifiers`	Reserved; sending it is 422

A list with one entry is an ordinary single-ID check. IDs are tried in the order you send them. The first Emirates ID (or the first entry, if there is none) is the check's main ID: it is the one shown as request.id_value.

In the result, each row in eligible_responses and other_responses adds matched_identifier (the ID that found the member) and identifier_attempts (each ID tried and its outcome). Both show only the last 4 characters of each ID, as does request.identifiers; the full list you sent is never returned.

"matched_identifier": {"id_type": "CARDNUMBER", "id_value": "******7890"},
"identifier_attempts": [
  {"id_type": "EMIRATESID", "id_value": "**************01-1", "outcome": "NOT_FOUND"},
  {"id_type": "CARDNUMBER", "id_value": "******7890", "outcome": "FOUND", "is_eligible": true}
]

GET /v4/eligibility-checks?q= finds the check by any card, member or policy number you sent, and by its main Emirates ID. Cancelling a check cancels every Daman request it opened, one per ID that reached Daman.
