# Query Exchange Order Detail

Retrieves one exchange order by order\_no or exchange\_id. Provide at least one query identifier. Both identifiers may be supplied in the same request.

**Endpoint**

`POST /remittance/exchange/query-order`

**Sandbox base URL:** `https://rem-api-sandbox.pagsmile.com`\
**Content-Type:** `application/json; charset=UTF-8`

The request uses the standard [Remittance API request envelope](https://docs.pagsmile.com/remittance-api/common). The fields below describe the decrypted `biz_data` object.

{% hint style="info" %}
**Requirement:** `M` = Mandatory, `O` = Optional, and `C` = Conditional. A conditional field is mandatory only when the condition stated in its description applies.
{% endhint %}

{% hint style="warning" %}
Encrypt `biz_data`, encrypt the AES key into `random_key`, and sign the request according to the Common request specification.
{% endhint %}

**Request body**

| `exchange_id` | long   | C           | Pagsmile-assigned unique identifier of the exchange. Required when order\_no is omitted. Provide at least one of order\_no or exchange\_id. Both fields may be supplied in the same request.                     |

**Plaintext `biz_data` example**

{% hint style="info" %}
This example includes mandatory fields and representative optional or conditional fields. Submit fields marked `C` only when the condition in the field description applies.
{% endhint %}

```json
{
  "order_no": "ORDER_202610220001",
  "exchange_id": 200001
}
```

**Request example**

```bash
curl --request POST \
  --url https://rem-api-sandbox.pagsmile.com/remittance/exchange/query-order \
  --header 'Content-Type: application/json; charset=UTF-8' \
  --data '{
    "partner_id": "<your_partner_id>",
    "app_id": "<your_app_id>",
    "timestamp": "2026-07-20 10:30:00",
    "version": "2.0",
    "language": "en",
    "random_key": "<RSA-encrypted AES key>",
    "request_id": "<globally_unique_request_id>",
    "sign_type": "RSA",
    "biz_data": "<AES-encrypted biz_data>"
  }'
```

{% hint style="info" %}
Use the `partner_id` and `app_id` assigned to your integration. The values above are placeholders.
{% endhint %}

**Response**

{% tabs %}
{% tab title="Success" %}
The `data` field in the response envelope is AES-encrypted. Decrypt `random_key` with your RSA private key, then use the resulting AES key to decrypt `data`. See [Security](https://docs.pagsmile.com/remittance-api/security) for implementation details.

**Encrypted response example**

```json
{
  "code": "10000",
  "msg": "Success",
  "data": "<AES-encrypted response data>",
  "random_key": "<RSA-encrypted AES key>",
  "sign_type": "RSA",
