How to Set Up the Adyen Integration in GoHighLevel

If you use ClickUp or other project management tools to organize your workflows, you can still centralize your payments inside GoHighLevel by connecting Adyen as a payment processor. This guide walks you step by step through enabling the Adyen integration so you can accept payments securely in your account.

The Adyen integration in GoHighLevel allows you to connect your Adyen account, configure your live API keys, and run transactions directly from your funnels and payment pages. Follow the instructions below carefully to avoid connection issues.

Prerequisites for GoHighLevel Adyen Integration

Before you begin, make sure you have the following in place to successfully connect Adyen inside GoHighLevel:

  • An active GoHighLevel account with access to the Payments / Integrations settings.
  • An active Adyen account with the necessary permissions to view and create API credentials.
  • Access to your Adyen Customer Area so you can copy required keys and identifiers.
  • Stable internet connection and admin access to your GoHighLevel sub-account or agency account, depending on where you are configuring payments.

Having these prerequisites ready will ensure your GoHighLevel Adyen setup is smooth and error free.

Where to Find Adyen Settings in GoHighLevel

To connect Adyen, you will start inside your GoHighLevel dashboard. The Adyen connection is managed under the payment and integration settings for each account.

  1. Log in to your GoHighLevel account.
  2. From the left-hand navigation, go to the Sub-Account or Agency where you want to enable payments.
  3. Open the Settings section.
  4. Click on Integrations or the Payments area where Adyen is supported.
  5. Locate the option for Adyen and click to begin the connection process.

Once you open the Adyen connection panel, GoHighLevel will prompt you for several API-related values that you must copy from your Adyen Customer Area.

Required Adyen Credentials for GoHighLevel

To complete the integration, GoHighLevel needs your Adyen account details and specific keys. While the exact labels can vary slightly depending on Adyen’s interface updates, you will generally need the following:

  • Merchant Account or Merchant ID
  • API Key (for live environment)
  • Client Key (for frontend components)
  • Any required Environment selection (such as live vs. test) as supported by GoHighLevel

You must obtain these values from your Adyen Customer Area, then paste them into the corresponding fields in GoHighLevel.

How to Retrieve Adyen Keys for GoHighLevel

Use the steps below inside your Adyen Customer Area to gather the credentials you will paste into the GoHighLevel integration screen:

  1. Sign in to your Adyen Customer Area.
  2. Navigate to the Developers or API Credentials section.
  3. Create a new API credential if required, or open an existing one you wish to use with GoHighLevel.
  4. Copy the API Key. Store it securely and avoid sharing it publicly.
  5. Locate and copy the Client Key, which may be displayed under frontend or web component settings.
  6. Confirm your Merchant Account name or ID and copy it.

After collecting these items, return to the Adyen section inside GoHighLevel and prepare to paste each value into the correct field.

Connecting Adyen to GoHighLevel

Once you have your Adyen keys, you can complete the integration inside GoHighLevel.

  1. In your GoHighLevel dashboard, open Settings > Integrations or Payments.
  2. Click on the Adyen option.
  3. Paste your Merchant Account or Merchant ID into the designated field.
  4. Paste your API Key into the API Key field.
  5. Paste your Client Key into the Client Key field.
  6. Choose the appropriate Environment (for example, Live if you are ready to process real payments).
  7. Click Save or Connect to finalize the setup.

GoHighLevel will attempt to validate the keys with Adyen. If the credentials are correct, the integration will connect successfully and you will see Adyen available as a payment option in supported features such as funnels or order forms.

Testing Your Adyen Connection in GoHighLevel

After the integration is connected, it is important to run a test payment flow to confirm everything is functioning correctly inside GoHighLevel.

  1. Create or open a funnel, website, or payment page inside GoHighLevel where payments are supported.
  2. Add a product or order form that uses Adyen as the payment processor, if such an option is available in your configuration.
  3. Preview the page and simulate a transaction using appropriate test or live card details as permitted by Adyen.
  4. Confirm the transaction appears in your Adyen dashboard and within any GoHighLevel payment reporting views.

If the payment succeeds, your GoHighLevel and Adyen configuration is ready for real customers.

Troubleshooting Adyen and GoHighLevel Integration

If you encounter issues connecting Adyen with GoHighLevel, review the common troubleshooting steps below:

  • Incorrect API Key or Client Key: Double-check you copied the full key strings from Adyen without extra spaces.
  • Wrong Merchant Account: Ensure the merchant account entered in GoHighLevel matches the account enabled for your Adyen API credentials.
  • Environment mismatch: If GoHighLevel expects live credentials, confirm that you are using live keys, not test keys.
  • Insufficient permissions: In Adyen, make sure the API credential has permission to process payments.
  • Recent changes not saved: If you update keys in Adyen, re-save the configuration in GoHighLevel.

If you continue to experience problems, you can reference the original Adyen integration guide in the GoHighLevel help center at this official article. It contains the latest screenshots and field names used in the current interface.

Best Practices When Using Adyen in GoHighLevel

To keep your integration secure and reliable, follow these recommended best practices when running Adyen payments inside GoHighLevel:

  • Rotate your Adyen API key periodically and update it in GoHighLevel when you do.
  • Limit access to Adyen credentials to only trusted team members.
  • Use role-based permissions in both platforms where available.
  • Test new funnels or payment flows in a staging or test environment before going live.
  • Monitor payment logs in Adyen and compare them with GoHighLevel reports to quickly spot discrepancies.

Consistently following these practices will reduce downtime and protect your customer payment data when using Adyen with GoHighLevel.
