Payment gateway plugins let your advertisers fund balances directly. All are listed as free integrations — you pay the gateway's own fees, not an integration charge.
Checkout.com — performance-focused global processing, positioned around enterprise-scale payments, fraud/risk/compliance, mobile payment flows and broad method and currency coverage.
Adyen — broad payment-method coverage and global scale, supporting online, in-app and recurring payments with multiple checkout integration options.
Paddle — a strong fit for a DSP sold as SaaS, using a merchant-of-record model. Paddle takes on tax, PCI compliance, refunds and chargebacks, alongside payments, subscriptions and metrics.
Braintree — a flexible gateway inside the PayPal ecosystem, with end-to-end checkout, mobile SDKs, global currency acceptance and local payment methods.
PayPal Checkout — a strong default for trust and conversion, particularly for self-serve deposits. Supports orders, payments, subscriptions, invoicing and disputes via REST APIs.
How to choose
- Self-serve advertisers depositing small amounts → PayPal Checkout, for conversion.
- You don't want to handle tax and compliance → Paddle, as merchant of record.
- Global scale, many local methods → Adyen or Checkout.com.
Offer more than one. Deposit friction is one of the quieter reasons a signed-up advertiser never actually starts spending.
