Known gotchas
The Amazon-Advertising-API-Scope header must contain the advertiser profile ID (not the account ID) specific to the marketplace being targeted; each marketplace has a separate profile.
Sponsored Products campaigns require the advertised products to be in active, buyable listings; ads referencing suppressed or inactive ASINs will be paused by Amazon.
Daily budget minimums vary by marketplace and campaign type; budgets below the floor are rejected with a budget validation error.
