Letta SMS Integration
Yes - Mobile Message does integrate with Letta!
New Message is the most direct trigger for notifying an operator when an agent uses send_message. New Agent can alert a technical owner when another agent is created, and New Project can notify a team when a workspace project begins. Mobile Message can Send SMS, Send SMS to List, Create Contact, or Add Contact to List. For example, a new agent can create a contact for follow-up, while a message event can alert an on-call recipient. Mobile Message cannot send a command back to a Letta agent through the listed actions. Each Zap is a one-directional workflow from a Letta event to a selected Mobile Message action, with Letta remaining the place where agents and projects are managed.
A Zapier account and subscription is required for this integration.
Please view Zapier's pricing page for further information.
