Quickstart

The most common integration path is:

Create a company API key from Configuración → Equipo y acceso → Empleados → Claves API.
Send requests to https://finsync.ar/api/....
Store the API key securely and send it in the x-api-key header.

Company keys act as the company. A personal employee key (fsync_emp_…) acts as that person and is limited by their role. See Authentication.

First request

curl --request GET \
  --url "https://finsync.ar/api/clients?page=1&pageSize=10" \
  --header "x-api-key: YOUR_API_KEY"

JavaScript example

const response = await fetch("https://finsync.ar/api/clients?page=1&pageSize=10", {
  headers: {
    "x-api-key": process.env.FINSYNC_API_KEY,
  },
});

if (!response.ok) {
  throw new Error(`FinSync request failed: ${response.status}`);
}

const payload = await response.json();
console.log(payload);

What to expect

Most endpoints return JSON.
Some list endpoints support pagination through page and pageSize.
