# Reply to a mention

`POST /v1/messaging/inbox/mentions/reply`

## Request

- Base URL: `https://apihub.co.il`
- URL: `https://apihub.co.il/v1/messaging/inbox/mentions/reply`
- Auth: HTTP bearer

Reply to a mention of the connected account. Supported on Instagram only.

Two shapes, selected by whether `commentId` is present:

- **Comment mention** (someone @mentioned the account inside a comment): pass both
  `mediaId` and `commentId`. Instagram posts a reply under that comment.
- **Caption mention** (someone @mentioned the account in their media caption, so no
  comment exists): pass `mediaId` only. Instagram posts a comment on their media.

Story mentions are not supported by Instagram's API.

`GET /v1/inbox/mentions` currently returns LinkedIn mentions only and does
not surface Instagram mentions. Source `mediaId` and `commentId` from Instagram's
`comments` webhook, which is where mention notifications are delivered for accounts
connected through Instagram Login.


**Billing:** Request; paid actions are priced in credits (see GET /v1/messaging/prices) · **Rate limit:** 60/min
