When your merchants have an existing relationship with a processor—boarded outside of Preczn—you can link those credentials to enable payment processing through the platform.

When to Use This

This applies when:

• Migrating merchants to Preczn - Your platform has merchants already processing with a provider, and you're adding Preczn to your stack
• Pre-boarded merchants - Merchants completed onboarding directly with a processor before using Preczn
• Processor-managed onboarding - The processor handled merchant onboarding outside of Preczn's onboarding flow

How It Works

1. Add the connection to the merchant record (if not already present)
2. Provide credentials via Dashboard or API
3. Preczn validates the credentials with the processor
4. Connection activates once validation succeeds

Credential Fields

Different processors require different credential combinations:

Refer to the specific processor's connection guide for required fields.

Methods

• Via Dashboard - Add credentials through the Merchant Vault UI
• Via API - Programmatically link credentials for bulk operations or integrations

Validation

When you submit credentials, Preczn validates them with the processor before saving. If validation fails, you'll receive an error indicating the issue.

On successful validation:

• The connection status updates (typically to Active)
• The merchant can begin processing payments through that connection
