Users can mention your business by tagging your Business Account alias in photos, or by @mentioning it in comments and captions. The Mentions API, which is a subset of Instagram Graph API endpoints and Webhooks, allows you to identify the media in which you were mentioned.
Please note that mentions on Stories are incompatible with the Mentions API.
The API consists of the following endpoints and webhooks:
Refer to each endpoint and webhook reference document for usage instructions.
We do not store Webhooks notification data. If you set up an Instagram Webhook that listens for mentions, you should store any received data if you plan on using it later.
You can listen for comment @mentions and reply to any that meet your criteria:
/user/mentioned_commentedge to get more information about each comment.
/user/mentionsedge to reply to those comments.
Your reply will appear as a sub-thread comment on the comment in which you were mentioned.
You can listen for caption @mentions and reply to any that meet your criteria:
/user/mentioned_mediaedge to get more information about each media object.
/user/mentionsedge to comment on those media objects.
