Quickstart | Lemmy API | Documentation

This guide walks you through your first call to the Lemmy API — reading the list of customer groups from your company. It takes just a few minutes.

Get your API key and company ID

Generate an API key in In-Motion Online under Configuratie → Integraties → API Keys, and grab your companyid from any In-Motion Online URL. See Authentication for details.

Check your connection

Call the Ping endpoint to confirm your API key works. It returns Pong.

curl https://app.inmotionsoftware.be/Lemmy_API_IS/rest/v1/Ping \
  -H "x-api-key: your-api-key"

A Pong response means your key is valid and you’re ready to make real requests. A 401 Unauthorized means the key is missing or invalid — see Authentication.

Make a request

Call the GetCustomerGroups endpoint with your API key and company ID. It’s a read-only request, so it’s a safe first call. Like every GET endpoint, it requires the x-page-offset and x-page-limit pagination headers.

curl https://app.inmotionsoftware.be/Lemmy_API_IS/rest/v1/GetCustomerGroups \
  -H "x-api-key: your-api-key" \
  -H "x-company-id: 1234" \
  -H "x-page-offset: 0" \
  -H "x-page-limit: 50"

Read the response

A successful request returns 200 OK and a JSON object containing your customer groups:

{
  "IsSuccess": true,
  "ErrorMessages": [],
  "Payload": [
    {
      "Code": "RETAIL",
      "Description": "Retail customers",
      "PaymentCondition": "30 days",
      "DeliveryCondition": "Standard",
      "Active": true
    }
  ]
}

If you get a 401 Unauthorized instead, double-check your API key and the x-company-id header — see Authentication.
