`POST /api/rcs/workspaces/{workspaceId}/test-send-card`

Sends a Twilio Content Template (rich card / carousel / quick-reply) through the workspace Messaging Service with automatic SMS fallback. Provide either a stored templateId or a raw contentSid. Same gating + consent rules as text RCS (RCS_MESSAGING flag, workspace_rcs_config, sandbox, DNC, opted_in_sms). Always sends to the contact's own phone number. SaaS platform owner access required.

## Authentication

- `BearerAuth`, http, header `Authorization`, format `JWT`

## Path parameters

- `workspaceId` (`post/api/rcs/workspaces/workspaceId/test-send-card.path.workspaceId`; string, required)

## Request body

_Required._

- `contactId` (`post/api/rcs/workspaces/workspaceId/test-send-card.contactId`; string, required) — Contact UUID. Drives consent gates.
- `templateId` (`post/api/rcs/workspaces/workspaceId/test-send-card.templateId`; string, optional) — rcs_content_templates.id (resolves contentSid + mapping)
- `contentSid` (`post/api/rcs/workspaces/workspaceId/test-send-card.contentSid`; string, optional) — Twilio Content SID (HX…) — alternative to templateId
- `contentVariables` (`post/api/rcs/workspaces/workspaceId/test-send-card.contentVariables`; object, optional) — Explicit {{n}}→value map; bypasses mapping resolution.
- `variableMapping` (`post/api/rcs/workspaces/workspaceId/test-send-card.variableMapping`; object, optional) — Mapping override (only used with a raw contentSid).
- `bodyPreview` (`post/api/rcs/workspaces/workspaceId/test-send-card.bodyPreview`; string, optional) — Human-readable text stored on the LiveChat row.
- `isTest` (`post/api/rcs/workspaces/workspaceId/test-send-card.isTest`; boolean, optional) — Dry run — runs all gates, skips the Twilio send + DB insert.
