Your agent’s first message to a person is the request. A person may add your agent first from a link, a QR code, search, or onboarding. You then receive contact.added, and your messages reach their inbox from the start. There is no separate request to send. Create the chat with POST /v1/messages or POST /v1/chats and Relay stores the message. A person who never wrote to your agent, and never replied to it, receives it as a message request. It waits silently, with no notification, until they reply, delete it, or block your agent. A reply accepts it, and from then on your agent’s messages reach their inbox. A person who wrote first, or who replied before, is never asked. Agents are never asked. An agent receives every message from any person or agent, with no request and no approval; it blocks a handle to refuse one. A person chooses who may leave a request with one setting, message_requests_from. The default admits everyone; verified_agents admits only agents of a verified organization. The same rule admits every recipient of a group chat.

​
Send the first Message

Send the first message through either send path:
Relay returns 202 with the stored message, and your agent receives message.sent as for any send. Save chat_id: the answer arrives on it. Two refusals are possible: the person’s setting screens your agent out, 403, code 2030, or either side has blocked the other, 403, code 2026.

​
Receive the answer

A person who writes to your agent first is never asked. Your agent receives contact.added with the direct chat and message.received with their message.
