Pro covers this server only. Subscribe with chatra_upgrade (it returns a Stripe Checkout link).

Get visitor
A chat visitor by id: name and contact details (basicInfo, integrationData and the merged `info`), custom form answers, location, browser, the link to the chat in the Chatra dashboard, the agent group, and the pages viewed in the latest visit. The id is the `clientId` your website passed to the widget or the visitor id from a Chatra webhook; Chatra has no endpoint to list or search visitors. GET /clients/{id}.
client_id必填Update visitor
WRITE: edit a visitor's basic info (name, email, phone, notes) exactly as if an agent edited it in the Chatra dashboard. Only the fields you pass change; `null` removes a value. Returns the updated visitor. PUT /clients/{id}.
nameemailnotesphoneclient_id必填Get message
One chat message by id (a visitor's or an agent's): type (agent or client), text, visitor id, agent id, timestamp (ms) and receivedFrom. Chatra has no endpoint to list a conversation, so the id must come from a send call or a webhook. GET /messages/{id}.
message_id必填Send message as an agent
WRITE: send a chat message to a visitor as a Chatra agent. The visitor sees it immediately in their chat window as if the agent typed it, so only call it with text the user asked you to send. It cannot be unsent except by deleting it. Say which agent writes: agent_id, or agent_email + agent_name + received_from (a dummy agent is created in Chatra when the email is unknown). For automated notices (order status, announcements) use chatra_push_message instead. Returns the new message with its id. POST /messages/.
text必填agent_idclient_id必填agent_nameagent_emailreceived_fromEdit agent message
WRITE: replace the text of an agent message that was sent earlier. Only agents' messages can be edited, not visitors'. The visitor sees the edited text. Returns the updated message. PUT /messages/{id}.
text必填message_id必填Delete agent message
WRITE, IRREVERSIBLE: delete an agent message from the conversation. Only agents' messages can be deleted, not visitors'. Returns the deleted message. DELETE /messages/{id}.
message_id必填Get pushed message
One pushed (automated) message sent earlier by id: text, visitor id, agent id, timestamp (ms), isPushed. GET /pushedMessages/{id}.
message_id必填Push message to a visitor
WRITE: send an automated message (order status, product update, announcement) to a visitor whose account is bound to Chatra through a clientId. It is delivered into the visitor's chat on behalf of a random agent, a given agent (agent_id) or a random agent of a group (group_id). It reaches a real customer and cannot be unsent except by deleting it, so only call it with text the user asked you to send. Returns the new message with its id. POST /pushedMessages/.
