Identify (Customer.io)

Use this action to identify a customer and set traits like email, name, or plan.

Add the action

1. In the WeWeb editor, go to the Integrations tab and add the Customer.io integration.
2. In an Interface workflow, click + Add action.
3. Select Customer.io → Identify.
4. Select the Connection you want to use.

Configure the action

• Customer ID: A unique ID for the customer (required).
• Traits: Optional details to store on the customer profile (for example { "first_name": "Pat", "plan": "premium" }).

Common pitfalls

Customer IDs are inconsistent

Use a stable ID (for example your internal user ID). If you change IDs, Customer.io may treat the same person as multiple customers.
