Replit

Getting started

Replit is a cloud app and agent builder with a built-in IDE, AI assistant, and deployment infrastructure. AgentPhone is a connector on Replit, so your Replit apps and agents can provision numbers, send SMS and iMessage, and place voice calls.

Setup

Open the Integrations tab in the Replit builder, find AgentPhone, and click Connect. Paste your AgentPhone API key from Settings. If the connector is unavailable in your workspace, store AGENTPHONE_API_KEY in Replit Secrets and use the SDK from server-side code. See Replit integrations for workspace availability. Verify setup by listing numbers before trying paid actions.

Using it

Once connected, your Replit app can call the AgentPhone API directly — buy numbers, send messages, and place calls. From there:

  • Use any AgentPhone SDK (or the REST API) in your Replit code.
  • Prefer natural language and tool use? Add the MCP server so your Replit agent can call AgentPhone autonomously.
  • To handle inbound calls and texts, point an AgentPhone webhook at your deployed app’s HTTPS handler route and save its signing secret in Secrets. Test signed delivery before processing incoming events. Hosted voice can answer calls without this handler.
