How do I find my Customer.io App API Key?

Log in to Customer.io, navigate to Settings > Account Settings > API Keys, and select the App API Keys tab to generate a new token.

02

Does it support EU regional accounts?

Yes! You can specify your region ('us' or 'eu') via the CUSTOMER_IO_REGION credential to ensure the agent connects to the correct data center.

03

Can I trigger a broadcast via AI?

Yes! Use the dispatch_broadcast tool with a specific broadcast ID. You can optionally provide JSON parameters for Liquid data injection.
