Get your mySilae payroll variables through an API

What you can build on Silae

• Get the payroll variables table

  Takes

  Employee or employee group (optional)

  Returns

  Employee, variable, value, dot status (red, blue or green), payroll period

  Employee, variables, overtime and additional hours, absences, advances, cycle validated or not

  Employee, variable, value

  Employee, variable, value saved, dot status

Automate Silae with a workflow

A workflow 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.

• Variables still flagged red before the cycle is validated

  Build this

  Starts

  Every month on the 20th at 9:00

  Step 1

  Get the payroll variables table for every employee.

  Step 2

  Keep the values with a red dot: incorrect or missing.

  Step 3

  Email you the list by employee, with each variable and its value.

• Declared advances, sent to your accounting system

  Build this

  Starts

  Every Friday at 17:00

  Step 1

  Get the declared advances of the current period.

  Step 2

  Keep the advances that were not there on the last run.

  Step 3

  Post employee, payment date, amount and label to your accounting webhook.

• Hours and bonuses from your HR system into Saisie des variables

  Build this

  Starts

  When your system calls the workflow's webhook with employees, variables and values

  Step 1

  For each row sent, enter the value in Saisie des variables for that employee and variable.

  Step 2

  Keep the rows whose dot did not turn green.

  Step 3

  Email you those rows, so you can correct them before you validate the cycle.

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, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get the payroll variables table” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "my.silae.fr/get_payroll_variables",
    "input": {
      "employee_group": "Atelier"
    }
  }'

{
  "status": "completed",
  "data": {
    "payroll_period": "2026-11",
    "variables": [
      {
        "employee": "Northwind, Claire",
        "variable": "Prime exceptionnelle",
        "value": 250,
        "status": "green"
      }
    ],
    "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.

Silae’s own options

Silae offers the mySilae Paie REST API to Silae partners who sign the API annex (Annexe 7) of their distribution contract, and to software vendors under contract with Silae. A partner can open an API account for one of its client companies. Billing is monthly, by the payslips in each payroll folder with an active API access configuration.

Signing in to Silae

mySilae signs you in at my.silae.fr with your email address and password, and a first-time user starts from Activate my account. With Fous you sign in once through mySilae's own sign-in with your own account. The login is sealed with AES-256, never returned by the API or written to logs, and a method reads and does only what your account can.

Worth knowing

A value is saved only on Enter

In Saisie des variables, a new value is saved only when you press Enter. A red dot means the value is incorrect or missing, blue that it is loading, green that it is correct and synced into mySilae Paie.

Your payroll manager sets what you see

The Saisie des variables module has to be activated by your payroll manager, and the employees an administrator sees depend on the rights configured for that account.

Validating the cycle freezes the values

After Valider le cycle de paie, the values are fixed and the payroll manager gets the validation report by email. Only the payroll manager can reopen variable entry, from mySilae Paie.

Advances: current period, no future dates

Acomptes déclarés shows only the advances of the current period, and the payment date cannot be in the future. The label, by default "Acompte du JJ/MM/AAAA", appears on the payslip.
