## Onboarding {#onboarding}

### Step 1. API project creation {#step-1-api-project-creation}

Once you are ready to begin the formal onboarding process, create an API project on the [Mastercard Developer Portal](https://developer.mastercard.com/account/sign-up).

### Step 2. Download Sandbox Keys {#step-2-download-sandbox-keys}

As per the [Quick Start Guide](https://developer.mastercard.com/doconomy-aland-index/documentation/quick-start-guide/index.md), download the Sandbox signing key.

### Step 3. Access to sandbox {#step-3-access-to-sandbox}

Before testing the APIs in the Sandbox environment, check out the [use cases](https://developer.mastercard.com/doconomy-aland-index/documentation/use-cases/index.md) and learn more about the API flow and its request-response parameters.

You can test the APIs with test data in the Sandbox environment in two ways:

1. **Direct integration with APIs using 'Insomnia' REST client.**   

   For more information on 'Insomnia' set-up, refer to this [page](https://github.com/Mastercard/insomnia-plugin-mastercard-auth#installation-).  

   Once the set up is done, check out the tutorial on [Test APIs in Sandbox using Insomnia](https://developer.mastercard.com/doconomy-aland-index/documentation/tutorials-and-guides/accessing-sandbox-tutorial/index.md).  

   <br />

2. **Create an application to integrate with APIs.**
   You could easily generate a simple Java client for the Doconomy Aland Index API by using the OpenAPI Generator and the Mastercard libraries for authentication.   

   Refer [Create Your Reference App](https://developer.mastercard.com/doconomy-aland-index/documentation/tutorials-and-guides/ref-app-tutorial/index.md) tutorial that shows how to generate a client and make an API call to the Doconomy Aland Index API.   

   You can also check the reference application provided on this [page](https://developer.mastercard.com/doconomy-aland-index/documentation/reference-app/index.md).

### Step 4. Go Live - Production environment {#step-4-go-live---production-environment}

You may request access to the Production environment after you have completed integration and testing for the Doconomy Aland Index API on the Sandbox environment.
