You can generate the API token in Criteo’s user interface.
To do this, go to Setup →User→API Information.
In the API User - SOAP API section, provide your first name, last name, and your email address. Then click Generate API token.
After that, your request status will be set to pending. To complete the API activation, click on the activation link in the email sent to the email address you’ve provided.
Please note:To generate your API, you need to register using a different email address from the one used to register your user profile. Criteo recommends adding an email address that is managed by more than one users as you can only generate one API.
