Summary

Sends an interactive card message via SeaTalk to a group chat or a single user. The card can include a title, description, image and buttons, and optionally replies in a thread.

Inputs

  • Recipient Type — Group Chat (default) posts to the group_chat endpoint; Direct Message (Employee Code) posts to the single_chat endpoint.
  • Recipient ID (required) — Group ID or the user's Employee Code, depending on Recipient Type.
  • Reply to Thread — Toggle that reveals the Thread ID field.
  • Thread ID — Thread to reply in; sent as thread_id on the message when Reply to Thread is on and a value is given.
  • Title — Card title element; omitted if empty.
  • Description — Card body text element (format 1); omitted if empty.
  • Card Image (Base64) — Base64 image content for an image element; omitted if empty.
  • Vertical Buttons — Up to 5 buttons, each stacked as its own row. Each has a Type (Callback or Redirect), Text and Value/URL. Callback sends the value as the callback payload; Redirect uses the value as a web link for both mobile and desktop.
  • Horizontal Button Groups — Up to 3 groups, each holding up to 3 side-by-side buttons with the same Type/Text/Value fields as vertical buttons.

Output shape

One output item per input item, containing the JSON response from the SeaTalk messaging API.

The node fetches one app access token per execution using the credentials' app ID and secret. Exceeding the button limits (5 vertical, 3 groups, 3 buttons per group) throws an error. With Continue On Fail enabled, failed items return {error: message} instead. Elements are ordered title, description, image, vertical buttons, then button groups.

Examples

Example 1: Post an approval request to a group with Approve and Reject buttons.

Recipient Type: Group Chat; Recipient ID: group ID; Title: 'Approval needed'; Description: request details; one Horizontal Button Group with two Callback buttons (Approve, Reject) with values.

Example 2: DM an employee a card linking to a dashboard.
