Summary

Sends an iMessage tapback reaction (love, like, dislike, laugh, emphasize, question) to a specific message in a chat via the Photon server's /api/v1/message/react endpoint.

Inputs

  • Chat GUID (required) — Chat identifier, e.g. iMessage;-;+1234567890 for a DM or iMessage;+;chat123456 for a group. If the chat isn't found, the node retries with alternate variants (iMessage;/any; prefixes, or a bare address expanded to a DM GUID).
  • Message GUID (required) — GUID of the message to react to, sent as selectedMessageGuid. Available from Get Messages output or the trigger node.
  • Reaction (required) — Tapback type: dislike, emphasize, laugh, like, love (default), or question.
  • Additional Fields > Part Index — Which part of a multi-part message to react to. Defaults to 0 (first part).

Output shape

One output item per input item, containing the Photon server's response (the data field if present, otherwise the full response body).

The exact response fields depend on the Photon server and aren't defined in the node. Not-found errors on all chat GUID variants raise an API error. With Continue On Fail enabled, failed items return {error: message}. Unlike send operations, this does not enforce the inbound-first policy.

Examples

Example 1: Auto-react with a heart to every incoming message from a trigger

Chat GUID and Message GUID set via expressions from the trigger output; Reaction = Love.

Example 2: Give a thumbs-up to a message found via Get Messages

Chat GUID = iMessage;-;+15551234567; Message GUID from the previous node's guid field; Reaction = Like.

Example 3: React to the second part of a multi-part message

Reaction = Laugh; Additional Fields > Part Index = 1.
