# Payment methods

> Choose, configure, and operate the payment methods shown in Lynq Checkout.

Checkout shows only the payment methods that are configured and enabled for the Payment Intent's environment. Provider credentials are managed from **Dashboard → Payment methods**.

## Common connection workflow

<Steps>
  <Step title="Obtain credentials" icon="building-2">
    Contact the payment-method owner and request merchant credentials for the environment you intend to use.
  </Step>

  <Step title="Select the environment" icon="toggle-right">
    Use the Dashboard environment switcher. Test and live connections are stored separately.
  </Step>

  <Step title="Configure the method" icon="settings-2">
    Open the payment method, enter every required value, then choose **Save and enable**.
  </Step>

  <Step title="Verify availability" icon="eye">
    Create a Payment Intent with keys from the same environment and confirm the method appears in Checkout.
  </Step>

  <Step title="Test end to end" icon="badge-check">
    Complete a payment and verify both the browser result and signed webhook delivery.
  </Step>
</Steps>

## How credentials are handled

Provider credentials are encrypted when saved. Secret credential values are not displayed again. When you update a connection, enter all secret fields again; saving replaces the current credentials and enables the method.

You can disable a configured method without deleting payment history. Disabled methods stop appearing in new checkout sessions for that environment.

<Warning>
  A configured payment method does not make mismatched keys work. The Payment Intent, publishable key, and payment-method connection must all belong to test mode or all belong to live mode.
</Warning>
