Create your API application

Once you have created your organization, you can access the My Apps page to begin creating your application. This page is also where you will manage your Criteo API applications.

To start creating your API application, click the Create a New App button in the top right corner of the page. This will initiate the application creation process.

Step 1 - Create application

App details

• Provide a name for your application, along with an optional description and app image.

❗️

API applications cannot be deleted. Once this step is completed, your application will appear in the "My Apps" dashboard.

Authentication method

• Criteo’s API supports two OAuth authentication methods: Client Credentials and Authorization Code. Each method has its own advantages, so before proceeding, we strongly recommend reviewing which authentication method is best suited to your application’s needs.

Trying to decide which OAuth method is right for you?

If you're unsure which authentication method to use, take a look at our OAuth App Implementation guide for an overview of each authentication method.

Step 2 - App activation

Once you've selected the appropriate authentication method, proceed to choose the service you’ll be using.

Services

• Choose the Criteo service your API application will interact with:
  • C-Growth and Marketing Solutions
  • C-Max and Retail Media

Step 3 - Authorizations

Domains

1. Choose the domains that define the permission levels your application will need. These domains determine which endpoints your application can access.

2. After selecting the appropriate domains, click Activate App.

⚠️

Once activated, you won’t be able to change the name, description, image, or app scope.

Retail Media Domains

Once you activate your application, you will be redirected to your application details page to complete the final steps of your application configuration.
