Two Ways to Integrate: Hosted vs. Direct
When you connect a payment processor to your site, there are two fundamental approaches. Understanding the difference helps you make the right call for your situation.
Coding For Adult Payment

Hosted Payment Pages (Easier, Recommended for Most)
With a hosted payment page, the customer clicks "Subscribe" on your site and gets redirected to a payment page hosted by your processor (CCBill, Segpay, etc.). The processor handles the entire transaction — collecting card info, processing the payment, handling security — and then sends the customer back to your site with a confirmation.
Advantages:
-
You never touch credit card data, which means you don't need PCI DSS Level 1 compliance (a massive regulatory burden)
The processor handles fraud detection, 3D Secure, and security
Integration is simple — often just linking to a URL with your account parameters
Most adult processors offer customizable payment page templates so it doesn't look completely disconnected from your site
Disadvantages:
-
The customer leaves your site to pay, which can reduce conversion rates (some customers get nervous about redirects)
Limited control over the payment page design and user experience
You're dependent on the processor's uptime and page speed
This is what most adult sites use, and it's what CCBill, Segpay, and Epoch all offer as their primary integration method. If you're starting out, use hosted pages. It's faster to implement and keeps you out of PCI compliance headaches.
Direct API Integration (More Control, More Responsibility)
Direct API integration means the customer enters their payment info on your site, and your server sends that data to the processor via API calls. The customer never leaves your site.
Advantages:
-
Seamless user experience — no redirects, everything stays on your domain
Full control over the payment form design
Can improve conversion rates since customers don't see a third-party page
Disadvantages:
-
You handle credit card data, which means full PCI DSS compliance. This is expensive and complex — annual audits, security requirements, penetration testing. Most small-to-mid-size operations can't justify this.
More complex integration — you're writing code that handles sensitive financial data
You're responsible for fraud detection and security on your end
Direct integration is for larger operations with dedicated development teams. If you're not sure whether you need it, you don't need it.
Key API Concepts Your Developer Needs to Know
Whether you're coding this yourself or hiring a developer, here are the technical concepts that matter for adult payment integration:
Webhooks (Postback URLs)
After a payment is processed, the processor needs to tell your site what happened. Webhooks are automated HTTP calls that the processor sends to a URL on your server with transaction details — success, failure, amount, subscription ID, etc. Your site receives this data and updates the customer's account status accordingly (activate membership, extend subscription, etc.).
This is critical and frequently messed up. If your webhook endpoint is broken or misconfigured, payments will process but your site won't know about them. Customers pay but can't access content. You get support tickets and chargebacks.
Subscription Management
Most adult sites run on recurring subscriptions. The API handles:
-
Initial signup — First payment and account creation
Recurring billing — Automatic charges at the subscription interval (monthly, quarterly, annual)
Cancellation — Customer or admin cancels, billing stops, access continues until the paid period ends
Rebilling failures — What happens when a recurring charge declines (retry logic, grace periods, account suspension)
Upgrades/downgrades — Changing subscription tiers, prorated billing
Each processor handles these slightly differently in their API. CCBill's subscription management API, for example, provides endpoints for querying subscription status, issuing refunds, and managing upgrade paths. Your developer needs to read the specific processor's documentation thoroughly.
Authentication and Security
API calls between your server and the processor need to be authenticated and encrypted. Standard patterns include:
-
API keys or tokens — Secret credentials that identify your merchant account
HTTPS only — All API communication must be encrypted. Never send payment data over HTTP.
IP whitelisting — Some processors only accept API calls from pre-approved IP addresses
Signature verification — Webhook payloads are often signed so you can verify they actually came from the processor and weren't spoofed
Testing and Sandbox Environments
Every major processor provides a sandbox (test) environment where you can simulate transactions without real money. Use it. Test every flow: successful payment, declined card, subscription cancellation, rebilling failure, webhook processing. Don't go live until you've verified every scenario in sandbox. A payment integration bug that lets people access content without paying — or charges them incorrectly — is expensive to fix after the fact.
Processor-Specific API Documentation
Each processor has their own API docs, SDKs, and integration guides. Point your developer at the right resources:
-
CCBill — Provides a RESTful API with detailed documentation, webhook system (WebhookIQ), and a FlexForms system for hosted payment pages. Their developer portal includes sandbox access and integration examples.
Segpay — REST API with straightforward documentation. Offers both hosted and embedded payment form options. Good webhook support with retry logic for failed deliveries.
Epoch — API documentation available through their merchant portal. Supports multiple integration methods including hosted pages and direct posting.
Verotel — Provides a FlexPay API for direct integration and hosted order pages. Documentation is available through the merchant control panel.
Common Integration Mistakes
-
Not handling webhook failures — If your webhook endpoint goes down temporarily, transactions get lost. Implement a reconciliation process that periodically checks the processor's records against your database to catch missed webhooks.
Hardcoding prices — Store subscription prices in your database or configuration, not in the code. You'll want to change pricing, run promotions, or A/B test different price points without a code deployment.
Ignoring rebilling failures — When a recurring charge fails, don't immediately kill access. Implement a grace period (3-7 days) with retry attempts. Most failed rebills succeed on retry — the customer's card may have been temporarily over limit or expired and been auto-replaced by the bank.
Not logging everything — Log every API call and webhook received with full request/response data. When something goes wrong (and it will), these logs are how you debug it. Store logs for at least 180 days for chargeback dispute evidence.
Skipping the sandbox — Going straight to production because "it's just a payment form" is how you charge real customers the wrong amount or give away free memberships.
Payment API integration isn't glamorous work, but getting it right is the difference between a site that makes money reliably and one that hemorrhages revenue through missed transactions, support tickets, and preventable chargebacks.
