We support multiple external providers and multiple accounts per provider, with configurable routing rules to manage transaction flows according to your needs.

Connection Management

Add a Connection

Prerequisites:
  • An active account with the target payment provider
  • Card payment method enabled with raw PAN payment capability
    • If required, contact us for an Attestation of Compliance (AoC) report
Steps to add a connection:
  1. Go to Settings -> Merchant (select the relevant merchant account if you have multiple)
  2. Click Linked Payment Services Providers, then New Connection
  3. Complete the connection form:
    1. Select your provider from the dropdown list
    2. Enter your API Key (we apply PCI requirements on API Key persistence)
    3. Provide your Channel Merchant ID
      • For AirWallex: Use the Client ID associated with your API Key
      • For Stripe: Optional - use account name (without spaces) or account ID for reference
    4. Enter the API endpoint URL
      • Some providers (e.g., Adyen) offer account-specific endpoints
      • Others (e.g., Stripe, AirWallex) use a common endpoint - refer to their developer guide
    5. Set up webhook integration:
      • Copy the Clink Generated Webhook URL
      • Create a webhook endpoint in your provider’s dashboard
      • Ensure payment-related events are selected
    6. Copy the webhook signature from your provider and paste it into Webhook Signature Key
    7. Click Confirm to save
