Your Secret Key authenticates every API request you make to Billplz. You'll need it to start integrating, whether you're setting up a plugin or building a custom integration.

Before you begin

  • Your Billplz account must be verified and active.
  • If you're testing, retrieve your Secret Key from your sandbox dashboard — sandbox and production accounts have separate keys.

Step 1: Go to Settings

In your Billplz dashboard, click your account name in the top right corner. Select Settings from the dropdown.

Billplz Dashboard - Opening the organization profile header menu to navigate to settings.

Step 2: Open Keys & Integration

On the Settings page, click the Keys & Integration tab.

Billplz Account Settings - Locating and selecting the "Keys & Integration" navigation tab.

Step 3: Copy your Secret Key

Under Billplz Secret Key, click Copy Billplz Secret Key. This copies the key to your clipboard.
