# Track your 海事一网通办 applications through an API

> Read the status of your 办件 (applications) and look up 船员电子证照 (crew electronic certificates) on 海事一网通办 with one API call each. Or have a workflow check every open application each morning and tell you which ones moved to 补正 or 办结.

## What you can build on 海事一网通办

### Check an application's status

Runs 办件查询 (application query) with an application number and the mobile number on file, and reads the 办件查询结果 (query result).

- Takes: Application number, mobile number
- Returns: Application number, permit number, item name, approval category, applicant, credit code, permit effective date, licensing authority, current status

### List my applications in 我的办件

Signs in and reads 我的办件 (my applications): each application's progress and result.

- Takes: Stage (optional)
- Returns: Application number, item name, stage, result

### Look up a crew electronic certificate

Searches 船员电子证照 under 查询服务 by certificate number or print number and reads the result table.

- Takes: Certificate number or print number, certificate name (optional)
- Returns: Certificate name, print number, certificate number, permit number, holder, issue date, certificate status

### Start a 船员服务一件事 application

Opens 船员服务一件事 (crew services in one go) from the home page and starts the combined application for a seafarer.

- Takes: Seafarer, certificates to apply for
- Returns: Application number, items applied for, stage

## Automate 海事一网通办 with a workflow

A [workflow](/product/workflows) runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

### Applications that moved to 补正 or 办结

Starts: Every weekday at 8:00 China time

1. List your applications in 我的办件 with their stage and result.
2. Keep the ones whose stage changed since the last run.
3. Email you the list, with 补正 first, then 办结.

### Weekly 证书状态 check of your crew's certificates

Starts: Every Monday at 7:00 China time

1. For each certificate number on your crew list, look it up in 船员电子证照.
2. Keep the certificates whose 证书状态 changed since the last run.
3. Post certificate number, holder, certificate name and status to your crew system's webhook.

### Status of applications your system is tracking

Starts: When your system calls the workflow's webhook with application and mobile numbers

1. For each application number, check its status through 办件查询.
2. Keep the ones whose 当前状态 is not the same as on the last run.
3. Post application number, item name, permit number, licensing authority and status to your webhook.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

## Once built, one call from your code

Once you have built a [method](/product/methods), it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Check an application's status” would look like.

Example request:

```
curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "zwfw.msa.gov.cn/check_application_status",
    "input": {
      "application_number": "SH2026110400172",
      "mobile_number": "13800000000"
    }
  }'
```

Example response:

```
{
  "status": "completed",
  "data": {
    "application_number": "SH2026110400172",
    "permit_number": null,
    "item_name": "船舶所有权登记",
    "approval_category": "行政许可",
    "applicant": "Acme Shipping Co., Ltd.",
    "credit_code": "91310000MA1K000000",
    "permit_effective_date": null,
    "licensing_authority": "Northwind 海事局",
    "current_status": "补正"
  }
}
```

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

## 海事一网通办’s own options

The MSA documents no public API for 海事一网通办. Applications are made and followed on the website, where 我的办件 shows progress and results and text messages arrive at 受理, 补正 and 办结. Since 12 September 2026, ship entry and exit reports are made in the 海事通 app instead of on the website.

| Option | What it covers | What it takes |
| --- | --- | --- |
| 海事通 app | 报港 (port reporting), including ship entry and exit reports: the MSA's notice set the website's report function to pause on 12 September 2026. | The 海事通 app on a phone. |
| 海事一网通办 WeChat mini program | The platform from WeChat, reached by a QR code on the home page. | WeChat and the QR code on the home page. |
| SMS reminders | A text message when an application is accepted, needs supplementing or is completed. | An application made while signed in, with a mobile number. |
| The website, by hand | 政务服务 and 监管服务 applications, 我的办件, 办件查询 and the 30 public queries under 查询服务. | A personal or legal entity/ship account; public queries need no sign-in. |

## Signing in to 海事一网通办

海事一网通办 has two sign-in types, 个人用户登录 (individuals) and 法人/船舶用户登录 (legal entities and ships), and accepts an account from the national government service platform or the MSA integrated service platform. With Fous, you sign in once through the site's own sign-in with your own account, and the login is sealed with AES-256 and never returned by the API or shown to code or AI agents.

## Worth knowing

- **Ship entry and exit reports left the website**: The website's 船舶进出港报告 (ship entry and exit report) function was set to pause from 00:00 on 12 September 2026, by the MSA's own notice. Port reports are made in the 海事通 app.
- **First sign-in asks for extra details**: An MSA integrated service platform account must add details on its first sign-in: individuals their ID card validity dates, companies their company and legal representative details. Ship accounts need nothing.
- **Individuals and companies sign in apart**: Personal accounts and legal entity or ship accounts use separate sign-in types. A company's applications are followed under its 法人/船舶 account.
- **Stages you can watch**: The platform names three points in an application, 受理 (accepted), 补正 (supplementing needed) and 办结 (completed), and sends a text message at each.

## Frequently asked questions

### Does 海事一网通办 have an API?

No public API is documented. The MSA offers the website, the 海事通 app, a WeChat mini program and text message reminders at 受理, 补正 and 办结. Applications and their progress are seen on the website under 我的办件 or through 办件查询.

### Can I file ship entry and exit reports on 海事一网通办?

Not since 12 September 2026. The MSA's notice set the website's ship entry and exit report function to pause at 00:00 that day and directs port reporting to the 海事通 app.

### Can I check an application without signing in?

Yes. 办件查询 on the 查询服务 page takes the application number and the mobile number used, and shows the item name, licensing authority and 当前状态 (current status).

### Can I check a seafarer's certificate?

Yes. 船员电子证照 under 查询服务 searches by certificate number or print number and shows the certificate name, holder, issue date and 证书状态 (certificate status).

### Is Fous affiliated with China Maritime Safety Administration?
