## 请求体参数

**issuing\_state** `string` *required* (default: AUS)

此数据库服务使用的 ISO 3166-1 alpha-3 国家代码。

示例：`AUS`

**services** `string` *required* (default: aus\_immicard)

包含此服务 ID 的数组。固定服务可使请求仅作用于这一个数据库。

示例：`aus_immicard`

**consent** `boolean` *required* (default: true)

终端用户对此服务的明确同意。

示例：`true`

**first\_name** `string` *required* (default: John)

需要验证的名字。

示例：`John`

**last\_name** `string` *required* (default: Doe)

需要验证的姓氏。

示例：`Doe`

**date\_of\_birth** `string` *required* (default: 1990-01-01)

出生日期，格式为 `YYYY-MM-DD`。

示例：`1990-01-01`

**immi\_card\_number** `string` *required* (default: SAMPLE-IMMI-12345)

此数据库服务所需的 `immi_card_number` 值。

示例：`SAMPLE-IMMI-12345`

**immi\_card\_expiry\_date** `string` *required* (default: 2030-01-01)

此数据库服务所需的 `immi_card_expiry_date` 值。

示例：`2030-01-01`

**vendor\_data** `string` (default: user-1234)

您为此人提供的稳定用户标识，例如您内部的用户 ID。Didit 使用它将独立检查关联到同一终端用户，并减少重复检测的干扰。

示例：`user-1234`

## 输入规则与验证说明

* 请按从用户或证件中采集的原样发送上述字段。
* Didit 会先校验必填字段，再调用数据库。在到达查询源之前被拒绝的请求不收费。

```

每次成功调用都会返回 HTTP `200`。**`outcome_code`** 字段说明实际发生的情况，例如区分真正的生物识别不匹配（`BIOMETRIC_NO_MATCH`）与无法读取的自拍照（`BIOMETRIC_IMAGE_UNUSABLE`）。所显示的 `status` 为默认功能状态；您配置的[部分匹配 / 无匹配操作](https://docs.didit.me/zh/core-technology/database-validation/database-validation-warnings.md)可以覆盖它。

**`MATCH`**：注册库已确认该身份，且所有检查的字段均匹配。

```json 200 OK — MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Approved",
  "issuing_state": "AUS",
  "match_type": "full_match",
  "validations": [
    {
      "outcome_code": "MATCH",
      "service_id": "aus_immicard",
      "service_name": "Australia - DVS - ImmiCard",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "first_name": "John",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe"
      },
      "validation": {
        "date_of_birth": "full_match",
        "full_name": "full_match",
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`PARTIAL_MATCH`**：找到了证件号码，但一个或多个个人字段（通常是姓名或出生日期）未完全匹配。

```json 200 OK — PARTIAL_MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "In Review",
  "issuing_state": "AUS",
  "match_type": "partial_match",
  "validations": [
    {
      "outcome_code": "PARTIAL_MATCH",
      "service_id": "aus_immicard",
      "service_name": "Australia - DVS - ImmiCard",
      "source_data": {
        "date_of_birth": "1990-01-01",
        "first_name": "John",
        "identification_number": "SAMPLE-ID-12345",
        "last_name": "Doe"
      },
      "validation": {
        "date_of_birth": "full_match",
        "full_name": "no_match",
        "identification_number": "full_match"
      }
    }
  ]
}
```

**`NO_MATCH`**：注册库未返回与提交数据匹配的结果。

```json 200 OK — NO_MATCH theme={null}
{
  "request_id": "req_01H…",
  "status": "Declined",
  "issuing_state": "AUS",
  "match_type": "no_match",
  "validations": [
    {
      "outcome_code": "NO_MATCH",
      "service_id": "aus_immicard",
      "service_name": "Australia - DVS - ImmiCard",
      "source_data": {
        "date_of_birth": "NO_MATCH",
        "full_name": "NO_MATCH",
        "identification_number": "NO_MATCH"
      },
      "validation": {
        "date_of_birth": "no_match",
        "full_name": "no_match",
        "identification_number": "no_match"
      }
    }
  ]
}
```

## 返回数据

`source_data` 中实际返回的字段取决于注册库返回的内容。`aus_immicard` 的生成示例目前记录了以下标准化结构：

* `date_of_birth`
* `first_name`
* `identification_number`
* `last_name`

## 定价与 SLA

澳大利亚 - DVS - ImmiCard 查询仅在 Didit 从验证源收到确定结果时计费。

* **单次调用价格：** \$0.75 USD。
* **计费方式：** 每次成功查询计费。注册库无法访问、缺少必填字段或请求在到达查询源之前被拒绝时，不收费。
* **延迟：** 典型 p95 低于 2 s。
* **可用性：** Didit 侧每季度为 99.9%；下游数据源的可用性因国家和数据集而异。
