Get started with the APIs

Follow this guide to set up your access and make your first API call.

Prerequisites

  • A developer account on this portal
  • An HTTP client: cURL, Postman or Insomnia

Step 1 — Create an account

  1. Click Sign up in the top right corner
  2. Fill in the registration form
  3. Confirm your email address via the link received
  4. Wait for your account to be approved by the administrator

Step 2 — Create an application

  1. Log in to the portal
  2. Go to My Applications
  3. Click Create an application
  4. Enter the name and description
  5. Select the APIs you want to access

Step 3 — Retrieve your credentials

Once your application is created:

  • Copy the Application Secret displayed and store it in a secure location. It will no longer be visible after this step — you can generate a new one if needed.

Never share your credentials or include them in your source code.

Step 4 — First API call

Once your application is approved, you can test an API call:

curl -X GET "https://api.stef.com/v1/transport/orders" \
  -H "X-STEF-Client-Id: <YOUR_APPLICATION_SECRET>" \
  -H "Content-Type: application/json"
