B2B Lock | How to prevent bot purchases, fraudulent orders, and unauthorized orders

⚙️ Prerequisites

Before setting up checkout lock, ensure you have:

• You must have the BSS B2B Lock app installed
• This feature requires a Shopify Plus plan.

🎮 How to use

Step 1: Navigate to Checkout Locks in the sidebar of the BSS B2B Lock app.

Step 2: Configure the general rule information.

Rule Name and Status (important – the status must be enabled for the rule to work).

Step 3: Configure Rules Based on Specific Conditions 📝

Configure your validation rules using these options:

• 👤 Customer conditions: Customer tags, email addresses, customer phone, login status
• 📦 Product conditions: Product tags, specific products, collections

Step 4: Set Up Logic and Error Message 💬

Condition Matching:

• 🔗 ALL: Acts as an AND condition, meaning all selected conditions must be met
• 🔀 ANY: Acts as an OR condition, meaning at least one selected condition must be met

Error Message:

⚠️ Default message: "Sorry, your order has been blocked."

This error message will be displayed when a checkout attempt is blocked based on your defined rules.

⚠️ Important Limitations

Please note: Currently, it's only possible to set up one checkout validation rule per store. We will support multiple rules soon.
