Adyen on WHMCS at a glance

WHMCS version
WHMCS 7.0+
Where you install it
WHMCS admin → Apps & Integrations
Coverage
Global, with local acquiring across Europe, North America, Asia-Pacific and Latin America. Adyen sets a minimum volume expectation, so it suits established merchants rather than new stores.
Currencies
  • EUR
  • GBP
  • USD
Billing models
One-time checkout and recurring renewals — WHMCS generates both, and the module handles both.
Cost
The module is free and open source. You pay Adyen's own fees, published on their pricing page. PaymentHood adds nothing on top.

Payment methods

What WHMCS customers can pay with

Each method Adyen supports appears in your WHMCS checkout. Enabling one is a PaymentHood dashboard setting — nothing changes on the WHMCS side.

Cards

Global and local card schemes with local acquiring in many markets

Digital wallets

Apple Pay, Google Pay, PayPal and regional wallets

Local methods

iDEAL, Bancontact, SOFORT, Klarna and market-specific rails

Bank transfers

SEPA and local bank payment rails

Setup

Connect Adyen to WHMCS

Four steps, no code. The full walkthrough with screenshots is in the WHMCS installation guide.

1

Open a Adyen account

Register with Adyen and finish their onboarding. Funds settle from Adyen to your own bank account.

2

Add it in PaymentHood

Paste your Adyen credentials into the PaymentHood dashboard. They stay server-side and never reach your storefront.

3

Install the module

Download the WHMCS module and install it from Apps & Integrations in your WHMCS admin.

4

Enable and test

Paste your PaymentHood API key into the module settings, run a sandbox order end to end, then switch to live.

Why PaymentHood

Rather than a direct Adyen module

A single-provider module works until you need a second provider. These are the parts you would otherwise build and maintain yourself.

Webhook security
HMAC-signed notification, validated before an order is released
Payment verification
Server-side payment result re-check against the Adyen API before fulfilment
Credentials
API key plus merchant account identifier, held server-side in PaymentHood
  • Add a second provider without touching your WHMCS checkout
  • Automatic failover when Adyen is unreachable, instead of a failed order
  • Idempotent charge creation, so a double-submitted order is not a double charge
  • One reconciliation view across every provider you run
  • Free and open source — read the module on GitHub
FAQ

Frequently Asked Questions

Usually not. Adyen prices and onboards for scale, and expects meaningful monthly volume. If you are starting out, a provider with no volume floor is a better first choice — and PaymentHood makes moving to Adyen later a dashboard change rather than a re-integration.

When Adyen acquires locally rather than routing cross-border, the transaction looks domestic to the issuing bank. That typically means a higher authorisation rate and lower scheme fees in that market — the main reason large multi-market merchants choose it.

Yes. Routing by country or currency is exactly what PaymentHood's orchestration layer is for, and it is configured in the dashboard rather than in your checkout.

No. Adyen bills you directly for its own fees, and PaymentHood takes no percentage and no per-transaction cut at any volume. See PaymentHood pricing.
