mentions works on sendText, sendImage, sendFile, sendVideo and editMessage, but it is hidden from the OpenAPI spec with @ApiHideProperty() in src/structures/chatting.dto.ts.
It was hidden in Nov 2023 (aff3b01 "Hide mentions", 2d64b26 "Hide mentions from send message"), but it is clearly maintained today:
- 1c41b8b (Nov 2025):
mentions: ["all"] for /api/sendText in groups on WEBJS, GOWS and NOWEB
- 869a343 (Nov 2025): mentions for send image, file and video
I tested it on WAHA 2026.8.2 with GOWS: POST /api/sendText with "mentions": ["<number>@c.us"] delivers the message with contextInfo.mentionedJID, and WhatsApp renders a clickable mention.
Because the field is not in the spec, clients generated from it can't offer it. For example, the n8n node (@devlikeapro/n8n-nodes-waha) is built from the OpenAPI file, so n8n users can't mention anyone without falling back to a raw HTTP Request.
Could mentions be documented in the spec (removing @ApiHideProperty())? If it was hidden on purpose (for example, engine limitations), a short note in the docs would also help.
