## How to connect to Snelstart

To set up an integration with **Snelstart**, you’ll need two keys: a **Connection Key** and a **Subscription Key**.

<Steps>
  <Step title="Prerequisites">
    Before you begin, make sure you have the following:

    * A **[Snelstart account](https://login.snelstart.nl/)**. **Note** that you must have the *inZicht* or *inControle* package to set up API access.
    * A **[Snelstart Developer account](https://b2bapi-developer.snelstart.nl/)**.
  </Step>

  <Step title="Retrieve the Connection Key">
    1. Go to the [Snelstart login page](https://login.snelstart.nl/) and sign in with your credentials.
    2. In the left sidebar, click **“Koppelingen”** (Links).
    3. Under **“Koppelingen”**, find **“Maatwerk”** (Custom integration) and select it.
    4. Click **“Koppeling instellen”** (Set up connection), agree to the scopes, and save your **Connection Key** somewhere safe.
  </Step>

  <Step title="Retrieve the Subscription Key">
    1. Visit the [Snelstart Developer Portal](https://b2bapi-developer.snelstart.nl/) and log in.
    2. If you don't already have an active subscription, navigate to **Products** and select a suitable plan (you can start with **Ontwikkeling & Test** – development and testing).
    3. Choose a name for your subscription, agree to the terms, and subscribe.
    4. Once your subscription is created, go to your **Profile** and copy one of your two **Subscription Keys** (the Primary Key is recommended).

    **Note:** Development keys are valid for 90 days with limited calls. For production, you'll need a production subscription key (€250 one-time fee). Apply at the [developer portal](https://b2bapi-developer.snelstart.nl/).
  </Step>

  <Step title="Set Up maesn Connect">
    1. Contact your **maesn representative** and provide the following information:
       * Your **Snelstart Subscription Key**
    2. In **maesn Connect**, paste your **Connection Key** into the **API Key** field and click **Submit**.
    3. If the key is valid, the connection will be established and a confirmation message will appear.
       Your Snelstart account is now successfully connected!
  </Step>
</Steps>

## Becoming a Snelstart Partner

To use the Snelstart API in production, you must become an **official Snelstart Partner**.
Once approved, your application gains access to **live customer environments** (beyond the default test company).

For detailed instructions and partner requirements, visit the [Snelstart Developer Portal](https://b2bapi-developer.snelstart.nl/).
