For Fetcher to be able to pull in your Daily PPC costs you will need to enable access to Amazon's Advertising API from your Profile and Settings page here:
If you have multiple accounts you will need to enable access to each one through the same process.
Access to the Advertising API is done by logging in using "Login with Amazon", not via the Seller Central Login. In some cases, the login credentials are the same as Seller Central and in some cases, they are not.
If the "Login to Amazon to Enable PPC" button stays blue then the sync was not successful. You will know the sync was successful when the blue button is replaced with "Enabled" like this:
Amazon's Advertising API only has one endpoint which is ".com" so do not be alarmed if you sell on another marketplace but are directed to ".com" when logging in. This is the correct URL and the place you want to be!
If you are having trouble getting the account enabled, a common issue we see is having one email address for multiple marketplaces.
The root cause of the issue is that to access the Advertising API you must use "Login with Amazon" which has a limitation if you are using the same email for different accounts in different regions. This mainly happens when you are using one email address to log in to an account in the North American region (NA = US, CA, and MX) and an account in the European Region (UK or EU = ES, FR, DE and IT). The Login with Amazon authorization mechanism doesn’t support authorizations for EU and NA accounts by using the same email address.
In order to get the account you are having trouble with enabled for PPC syncing, please add a new user to that account from Seller Central with an email address that wasn’t added to any other accounts (an email that is different from any you have used for your account before).
To do this go to Settings and then User Permissions.
Then you will be able to add a new user email here:
Once this new user is active, you can use this new user to authorize the application from Fetcher. Please also make sure that this new user has the “View & Edit” permission for Campaign Manager which can be set in Seller Central under Settings > User Permissions > Manage Permissions.
And that is it! You should no be able to enable the sync so Fetcher can start collecting your Daily PPC costs using this new user's credentials.
