Thanks for the questions — answers below.
What is amountMicros?
@NevermindBuild has it right: money in the API is micro-USD, where 1 USD = 1,000,000 micros, so “50000000” is $50.00. Divide by 1,000,000 to get dollars.
Will we get an endpoint for ads analytics?
Reporting is deliberately not in v1 of the Ads API. Instead of standing up a second reporting surface that would sit next to the one you already use, the direction is for campaign metrics to be available through the Analytics API alongside your other experience metrics. That will be available soon, for now Ads Manager remains the place to read campaign performance.
Will we get support for uploading and managing creatives?
Uploading already works today; it just doesn’t live in the Ads API. Upload your image through the Open Cloud Assets API, then pass the returned asset ID in creativeAssetIds when you create the campaign. Assets you reference that way are automatically registered in your account’s creative library, and GET /ads-management/v1/creatives lists that library — asset ID, name, moderation status, dimensions, and source — so you can find and reuse images that have already cleared review.
What isn’t in v1 is creative management through the API. Renaming, archiving, and deleting creatives are still Ads Manager only, and creativeAssetIds is fixed once a campaign is created. Changing creatives means creating a new campaign.
