Send an agent reply

Send a reply into an existing agent conversation from server-side code. Use this when you are not running @novu/framework on the bridge (for example with the Python, Go, PHP, .NET, or Java SDKs), or when another backend service needs to post into a live conversation.

The request body is a bag of optional actions. Provide at least one of reply, edit, resolve, signals, toolResults, toolApprovalRequest, addReactions, deleteMessages, typing, or error. Named examples in the OpenAPI spec cover the common shapes.

When a reply or edit is delivered, the response data contains messageId and platformThreadId. Side-effect-only requests return data: null.

For the TypeScript bridge API (ctx.reply, cards, signals), see Reply.
