Integrating your Customix account with PrintBelle lets you automate your fulfillment process with your API key. Follow these simple steps to get connected.

Step 1: Retrieve your PrintBelle API Key

• Go to the PrintBelle Fulfillment Portal and log in to your account.
• In the top right corner, hover over your profile avatar (next to your name) and select My account from the dropdown menu.

• Scroll down to the Setting section at the bottom of the page, then locate the API Key field and click the copy icon (or highlight and copy the string of characters).

Step 2: Connect to Customix

• Open your Customix backend dashboard, in the left-hand sidebar, click on Settings. Nex, navigate to the Fulfillments tab in the top navigation bar.
• From the list of API fulfillment providers, select Printbelle.

• In the Credential section, paste your copied API key into the API key field.
• Click Check API Key to verify, then click Save in the top right corner to finalize the connection.

Quick Tips:

• Keep your key secret: Do not share your API key with anyone. If it is ever compromised, contact PrintBelle support immediately.
• Automatic Payments: Once connected, you can toggle the "Automatically Pay Orders" setting in your PrintBelle dashboard to ensure your orders are processed without manual intervention (as long as your wallet balance is sufficient).
