PayPal for Advertisers | Advertisers can now automatically increase their budget in Atomx. Payments from your advertisers will automatically arrive in your Buying Network PayPal account and be added to the advertiser’s budget. Three conditions need to be met to make this happen:

1: The Buying Network has valid PayPal address added to its Network Details.
2: The advertiser’s budget IS NOT set to unlimited, but to a value of at least $0.01. For the record: Number “0” equals “unlimited”.
3) The advertiser’s “Budget editable” option must be set to “No”.

Once these three options are set, your advertiser will see a blue “Increase Budget” button next his Budget.
