To update you campaign CPC using the Criteo API, you must first call the "clientLogin" query to get your authentication token.
After successfully call the "clientrLogin" query, you must:
- call the "getBudgets" query to work on a budget with the remaining amount (optional if you already have a budget or campaign ID)
- call the "getCampaigns" query to retrieve campaign IDs, and categories you wish to update (optional if you already have a campaign ID)
- call the "getCategories" query to retrieve category Names.
After successful implementing the above steps, you can then select which campaigns to update the CPC for.
Please note: that the above step can also be performed using the single query "mutateCampaigns".
