Why can't I find/tag Instagram collaborators?
DesktopStart
Instagram collaborator tagging lets you invite other accounts to share a post. Once they accept the invitation, the post appears on their profiles too, with shared engagement.
In Publer, you can tag collaborators on photos, carousel posts, and Reels.
If you cannot find or tag a collaborator, check the following.
1. Your Instagram connection does not support collaborator tagging
Collaborator tagging is currently supported for Instagram accounts connected to Publer through Facebook.
If the option is unavailable, make sure your Instagram account is linked to a Facebook Page and connected to Publer through Facebook.
2. The collaborator’s account is not eligible
The collaborator must have a public account that has been active for at least 30 days. Private or age-restricted accounts are not eligible through Instagram’s API.
Accounts with more than two policy violations may also be restricted. The account owner should check their account status in Instagram and appeal any restrictions there.
3. The username is incorrect or does not appear in suggestions
Double-check the collaborator’s exact Instagram username before saving.
Usernames are not case-sensitive, but spelling matters. If a collaborator’s username is invalid, the post may be published without that collaborator.
4. You have reached the collaborator limit
You can tag up to three collaborators per post through Publer. For a carousel, this limit applies to the whole post, not to each image.
5. The collaborator has not accepted the invitation
The collaborator needs to accept the invitation in Instagram before the post appears on their profile as a collaboration.
If they do not receive the invitation, ask them to:
- Check that their account is public.
- Try switching to a Professional account.
- Log out of Instagram and log back in.
6. The collaborator tag was not saved correctly
Make sure you select the collaborator-tagging option and save your tags before finishing the post.
To tag a collaborator on an Instagram post:
- Go to Create in Publer.
- Select your Instagram account and upload your photo, carousel, or Reel.
- Hover over the photo or video and click on the tag icon in the bottom-right corner.
- Select Tag collaborator, then click anywhere on the photo or video.
- Enter the collaborator’s Instagram username in the field on the right.
- To remove a collaborator, click on the x next to their tag.
- Once you have added your collaborators, click on Save Tags.
- Review the post preview, then finish creating and scheduling your post.
