Generate an Access Token

  • This endpoint generates a new access token using your API credentials or authorization code.
  • To comply with the OAuth2 standards of using client_credentials, Criteo API authorization supports Content-Type: application/x-www-form-urlencoded, as shown in the example below:
POST https://api.criteo.com/oauth2/token

# Sample Request
  
curl --location --request POST 'https://api.criteo.com/oauth2/token'   --header 'Content-Type: application/x-www-form-urlencoded'   --data-urlencode 'client_id=CLIENT_ID'   --data-urlencode 'client_secret=CLIENT_SECRET'   --data-urlencode 'grant_type=client_credentials'
