## What you can build on İşveren Sistemi

### Get a teşvik control list

Reads a teşvik control list such as 4447/GEÇİCİ 10. MADDE KONTROL İŞLEMLERİ for the 6111 incentive, with each insured person's periods and approval status.

- Takes: Control list, for example 06111 or 27103
- Returns: Insured person, incentive start and end period, average headcount condition, hire date, leaving date, approval status

### Get the current-period debt

Reads Cari dönem borç bilgisi (current-period debt) for the workplace you signed in to: what has to be paid at the bank.

- Takes: Nothing
- Returns: Workplace registration number, period, amount due, due date

### Read the müfredat kartı

Reads the Müfredat kartı menu, which lists every tahakkuk (accrual) and tahsilat (collection) movement of the workplace.

- Takes: Period from, period to (optional)
- Returns: Period, movement type, accrued amount, collected amount, date

### Check potential incentives for a new hire

Runs Potansiyel Teşvik Sorgulama (potential incentive query) under Teşvikler ve Tanımlar for a person and reads which incentives meet their conditions.

- Takes: TC kimlik no, earnings, education status
- Returns: Incentive, conditions met or not

## Automate İşveren Sistemi 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.

### ONAYSIZ rows in the 6111 control list

Starts: Every Monday at 8:00

1. Get the 4447/GEÇİCİ 10. MADDE KONTROL İŞLEMLERİ list for your workplace.
2. Keep the insured people whose Onay column says ONAYSIZ.
3. Email you each one with hire date and incentive period, so you can apply to the social security centre for diploma approval.

### Current-period debt, sent to accounting

Starts: Every weekday at 9:00

1. Get the Cari dönem borç bilgisi for your workplace.
2. Keep the debt lines that changed since the last run.
3. Post period, amount due and due date to your accounting system's webhook.

### Incentive check for each new hire

Starts: When your payroll system calls the workflow's webhook with a new hire

1. Run the potential incentive query with the TC kimlik no, earnings and education status received.
2. Keep the incentives whose conditions are met.
3. Email you a short summary of them before the teşvik is defined.

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 “Get a teşvik control list” 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": "uyg.sgk.gov.tr/get_tesvik_control_list",
    "input": {
      "control_list": "06111"
    }
  }'
```

Example response:

```
{
  "status": "completed",
  "data": {
    "control_list": "4447/GEÇİCİ 10. MADDE KONTROL İŞLEMLERİ",
    "document_number": "06111",
    "insured": [
      {
        "tc_kimlik_no": "12345678950",
        "incentive_start_period": "2026/03",
        "incentive_end_period": "2028/08",
        "average_headcount_condition": 4,
        "hire_date": "2026-03-09",
        "leaving_date": null,
        "approval": "ONAYSIZ"
      }
    ],
    "count": 1
  }
}
```

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.

## İşveren Sistemi’s own options

SGK offers employers two web services: one for 4/a hire and termination notices, and ws-vizite for sick reports and the notice that an employee did not work. No documented web service covers İşveren Sistemi's own screens: the teşvik lists, müfredat kartı, debt and restructuring plans. You use them by hand, signed in to one workplace.

| Option | What it covers | What it takes |
| --- | --- | --- |
| İşe giriş ve ayrılış web servisi | Sends 4/a hire and termination notices from your own software. A toplu giriş XML upload does the same in batches. | SGK's usage guide. A test environment is set up when you email SGK your workplace sicil. |
| ws-vizite web servisi | Reads iş göremezlik (incapacity) reports and sends the çalışmadı (did not work) notice; also lists work-accident hospital records. | A Vizite user name, user code and password, and a token. |
| İşveren Sistemi by hand | Teşvik definitions and control lists, müfredat kartı, cari dönem borç bilgisi, Türkiye Geneli İşyerlerim and 6552, 6736, 7020 and 7143 restructuring plans. | The e-SGK user name, Sistem Şifresi and İşyeri Şifresi of each workplace. |

## Signing in to İşveren Sistemi

İşveren Sistemi Kullanıcı Girişi asks for a Kullanıcı Adı (user name), a Sistem Şifresi (system password) and an İşyeri Şifresi (workplace password). These e-SGK passwords are issued through e-Devlet, and each sign-in opens one workplace. With Fous you sign in through İşveren Sistemi's own sign-in with your own account, and the login is sealed with AES-256, never returned by the API or written to logs.

## Worth knowing

- **Unpaid debt blocks incentives**: Past-period debt must be paid before an incentive applies, and the current-period debt by its due date. Since 2022/01 the five-point reduction checks debt across all of the employer's workplaces in Türkiye.
- **Debt is shown here, paid at a bank**: SGK's guide says debt can be queried in İşveren Sistemi and at banks, but paid only through banks. The bank reference is the first 26 digits of the 29-digit Sicil No shown at the top of every screen.
- **Kolay İşverenlik accrues on its own**: For Kolay İşverenlik workplaces the period accruals are created automatically, usually between the 16th and 18th of the following month, in the saved incentive order.
- **An unsaved incentive order means no incentive**: Defined incentives apply only after the order is saved with Kaydet, and an order of 00000 means accruals without incentive. Pressing Sigortalı Beyan Güncelle ends the current beyan and starts a new one.

## Frequently asked questions

### Does SGK İşveren Sistemi have an API?

Not for its own screens. SGK publishes web services for 4/a hire and termination notices and for vizite sick reports, but the teşvik lists, müfredat kartı, debt and restructuring plans in İşveren Sistemi are used through the website, one workplace at a time.

### Where do I get the İşveren Sistemi passwords?

From e-Devlet. SGK's guide sends employers to E-SGK Uygulamaları ve E-SGK Şifre on the e-Devlet Kapısı for the workplace code, Sistem Şifresi and İşyeri Şifresi, after the e-Bildirge user has been approved there.

### Where is the monthly prim ve hizmet belgesi filed?

Not in İşveren Sistemi. Since 2020/03 it is filed as part of the Muhtasar ve Prim Hizmet Beyannamesi, except by general-budget public bodies. Those that still file with SGK use e-Bildirge V2.

### How do I see which incentives a new employee qualifies for?

Use Potansiyel Teşvik Sorgulama under Teşvikler ve Tanımlar. Enter the TC kimlik no, earnings and education status: incentives whose conditions are met show in green, the others in pink. SGK suggests keeping a screenshot in the workplace file.

### Is Fous affiliated with Sosyal Güvenlik Kurumu?

No. Fous is an independent product. You use it with your own İşveren Sistemi account, and a method reads and does only what that account can.

Fous is an independent product: it is not affiliated with, endorsed by or sponsored by the operator of SGK İşveren Sistemi (Sosyal Güvenlik Kurumu). The name is used only to say which system this page is about. Something here wrong or out of date? Write to legal@fous.com.
