How to Set Up Adyen Payments in GoHighLevel — Accept Global Payments

Accepting global payments shouldn't require a PhD in payment processing. Yet many agencies using GoHighLevel struggle to connect international payment gateways—leaving money on the table and frustrating clients in Europe and North America.

Prerequisites: What You Need Before Setup

Before you begin connecting Adyen to GoHighLevel, make sure you have:

1. An active Adyen merchant account. If you don't have one yet, sign up at adyen.com and complete their verification process (typically 1-3 business days). You'll need basic business information and banking details.
2. GoHighLevel admin access. You need to be an account owner or have permissions to manage integrations and payment settings.
3. API credentials from Adyen. Specifically, you'll need your Merchant Account name and API key. These live in your Adyen dashboard under Settings > Developers > API credentials.
4. A live or test environment. Adyen gives you both environments—use test first to validate everything works before accepting real payments.

Setting aside 15-20 minutes for this setup is realistic. Most of that time goes to copying API credentials between systems.

Step-by-Step: Connect Your Adyen Account

Step 1: Log into your GoHighLevel account

From your dashboard, navigate to Integrations (or Settings > Integrations, depending on your account structure). Look for the Payments section.

Step 2: Find and select Adyen

Scroll through available payment processors until you find Adyen. Click Connect or Setup.

Step 3: Gather your API credentials

Open a new browser tab and log into your Adyen dashboard. Navigate to:

• Settings > Developers > API credentials

You'll see your Merchant Account name and API keys listed. For the GoHighLevel integration, you'll need:

• Merchant Account name (the identifier for your processing account)
• API Key (a long alphanumeric string used for authentication)

Step 4: Paste credentials into GoHighLevel

Return to GoHighLevel and paste both credentials into the corresponding fields. Double-check for typos—even a single character off will break the connection.

Step 5: Select your environment

Choose Test if you want to validate the integration without processing real payments. Choose Live only after you've tested thoroughly (see Step 5 below).

Step 6: Authorize and save

Click Connect or Authorize. GoHighLevel will verify your credentials with Adyen. If successful, you'll see a confirmation message and your Adyen account is now live in GoHighLevel.

Configure Payment Forms and Products

Connecting Adyen is just the foundation. Now you need to actually create payment experiences for your clients.

Creating a payment form:

Navigate to Funnels > Forms and create a new form (or edit an existing one). Under the Payment section, select Adyen as your processor. Configure:

• Payment amount: Fixed price or dynamic (based on form field input)
• Currency: Select the currency appropriate for your customer base
• Payment description: What shows up on the customer's statement (keep it under 80 characters)
• Redirect after payment: Where to send users after a successful transaction

Setting up products:

If you're selling multiple products or services, create them in Products & Services. Each product can have its own price, description, and payment terms. When you add products to a form or funnel, Adyen will process the total amount due.

Configuring recurring payments:

For subscriptions or monthly retainers, enable Recurring Billing in your form settings. Adyen will automatically charge the customer's card on your specified schedule. GoHighLevel syncs this data so you can track subscription status and manage cancellations.

Test Your Adyen Integration

Never launch a payment form in live mode without thorough testing. Here's the process:

1. Verify your environment is set to Test

In your Adyen settings within GoHighLevel, confirm you're in Test mode, not Live.

2. Use test card numbers

Adyen provides specific test card numbers that trigger different responses:

• 4111111111111111 — Authorized payment (success)
• 5555555555554444 — Visa test card
• 378282246310005 — American Express test card

Use any future expiration date and any 3-digit CVC.

3. Run a test transaction

Go to your payment form (not in GoHighLevel, but on the actual live URL where your form is embedded) and submit a test payment using one of the test card numbers. Complete the form as a customer would.

4. Verify the transaction appears in both systems

Check your Adyen dashboard: Transactions > Payments. You should see the test payment with status Authorized. Then check GoHighLevel: Contacts > (the test contact) > Payment History. The transaction should appear there too, confirming data syncing works.

5. Test a refund (optional but recommended)

Still in test mode, process a refund on your test transaction to ensure that workflow is functional. More on this below.

Once all tests pass, switch your integration to Live mode in GoHighLevel settings and you're ready to accept real payments.

Manage Refunds and Supported Features

Processing refunds:

When a customer requests a refund, navigate to the contact in GoHighLevel and find the transaction in their payment history. Click the transaction and select Refund. You can refund the full amount or a partial amount. Adyen processes the refund and the funds return to the customer's original payment method within 1-3 business days (depending on the bank).

What Adyen integration supports in GoHighLevel:

• Credit and debit card payments (Visa, Mastercard, American Express, Discover)
• Recurring billing and subscriptions
• Partial and full refunds
• Multiple currencies
• Automatic customer data sync to your CRM
• Payment status tracking in contact records

Routing and compliance:

Adyen automatically routes transactions through the appropriate payment network based on card type, customer location, and regulatory requirements. If a customer is in Europe, Adyen ensures Strong Customer Authentication (SCA) flows are triggered where required. You don't need to configure this—it's handled server-side.
