Ways to connect
Every number you add can be reached three ways. They use the same account and the same numbers, so you can use more than one.

API
Your code calls https://api.api-supp.com/v1/… with the number's token, and gets replies and read receipts on your webhook. Start with Before you start.
Cloud MCP
Add our server to ChatGPT, Claude or Claude Code and sign in. The agent can then work with every number on your account.

Want an agent to answer on its own?
Forward a number's incoming messages to your cloud agent, and it replies through the cloud MCP. See Auto-reply agent.
