Track client response time with n8n

In ReplyTime, go to Settings → API Keys and create one named after this workflow, e.g. “n8n — production.” Copy the secret immediately — it's shown only once.

Start with a trigger node for wherever your clients message you (a webhook trigger, Gmail, Slack, or similar). Add an HTTP Request node, method POST, to the URL below.

https://replytime.net/api/v1/events/inbound

Under Authentication, choose Generic Credential Type → Header Auth, with name Authorization and the value below. Set Body Content Type to JSON and map the previous node's fields into client, channel, and message.

Bearer rt_xxxxxxxxxxxxxxxxxxxxxxxx

Clone the workflow, trigger it on your own reply instead, and point the HTTP Request node at /api/v1/events/outbound. This is the workflow that stops the clock.

Run the workflow once with real data, then check the client's conversation in the ReplyTime dashboard — the countdown should start and stop as expected.

Example payload

Both endpoints accept the same shape. Set message.source_tool so you can tell where an event came from later.
