What you need#
- A Threads profile. Heropost connects the profile you sign in with.
- A plan that includes Threads. Every plan sold today does. The original Lifetime plan can't connect Threads: choosing it opens Time to Level up!. Some older plans have a separate, smaller allowance for X, TikTok, Google Business Profile, Threads and Bluesky together; see How many accounts your plan includes.
- Pop-ups allowed for app.heropost.io.
- The owner or Admin role in your Heropost workspace.
Threads is separate from Instagram in Heropost: connecting Instagram doesn't connect Threads, and the other way round.
Connect your Threads profile#
- Click your workspace name at the top of Heropost, then Accounts.
- Press Add Profile and choose Threads.
- Threads opens in a small window. Log in if Threads asks, and allow access.
- The window shows "Connecting your Threads account… This window will close automatically." and closes.
- Add Social Account lists your profile under Profiles. Tick it and press Done.
- Heropost shows Account successfully added.
Threads' window uses the profile that's logged in at threads.net in your browser. To add a different profile, log out there first, or use a private window, then add Threads again.
What you can post#
| Post | Supported | Details |
|---|---|---|
| Text only | Yes | Post Type Media/Caption with no media. |
| Photo | Yes | One JPG or PNG, up to 8 MB. |
| Video | Yes | One MP4 or MOV, up to 1 GB. Threads' own rules allow up to 5 minutes. |
| Carousel | Yes | 2 to 20 photos and videos, mixed in any order. |
| Link post | Yes | Post Type Link, with your text. Threads shows a preview card for the link. A link post can't carry your own photos or video. |
| Polls, topics, alt text | No |
| Text | Limit |
|---|---|
| Caption | 500 characters. Required on a Link post. |
| First comment | 500 characters, posted as a reply to your post |
Media tips. The Media Requirements link in the upload box lists Threads' rules. Threads officially supports JPG and PNG photos, scales photos to between 320 and 1,440 pixels wide, and recommends 9:16 video to avoid cropping or blank space. Heropost checks file size and count, not video length or shape.
Processing. Threads processes photos and videos before they go live. Heropost waits up to 15 minutes for it to finish.
Options in the Threads tab#
- Post Type: Media/Caption (text, photos, videos or a carousel) or Link.
- Link: the address for a Link post. Use the full address, starting with https://.
- First Comment: published as a reply to your post, from your profile, right after it goes out. See Add a first comment.
- Take media, caption, first comment from the All tab: switch it on to reuse the All tab's content. On a Link post, it takes the link instead of the media.
Photos get your watermark, if you set one for the account or the workspace.
Limits and holds#
- When Threads limits an account, Heropost stops publishing to it for a while, to protect it. Posts due in that time fail with "Threads is temporarily limiting how often this account can post. Heropost paused publishing to it until {date} UTC to protect the account. This post was not published to it — schedule it again later." If Threads keeps limiting the account, the pauses get longer. Reconnecting doesn't lift them. See When a network limits an account.
- What to do: wait until the time in the message, send the held posts again with Duplicate Failed, and spread your posts through the day.
- Connections expire. Threads sets how long Heropost's access lasts. Heropost renews it automatically in the week before it expires. If it lapses anyway, Hero_Agent on Home lists the profile as needing attention: reconnect it.
Analytics and the Social Inbox#
- Analytics: views, likes, replies and shares for each post. When you connect a profile, Heropost also imports up to 100 of its recent posts. A post with no views or interactions yet doesn't appear until it has some. Follower growth isn't tracked for Threads. See Analytics.
- Social Inbox: replies to your 25 most recent posts appear under Comments, where you can answer them. Mentions of your profile appear under Mentions. See The Social Inbox.
Errors and fixes#
When you connect or reconnect#
| Message | What it means | What to do |
|---|---|---|
| Time to Level up! | Your plan doesn't include Threads (the original Lifetime plan). | Press Upgrade to see plans. See Lifetime plans explained. |
| "Looks like you've reached the limit of your plan. Please upgrade your account to access for features." | The workspace owner's plan has no room for another account, or for another account on these networks. | Remove an account you don't use, or upgrade. See account limits. |

| "Selected account not found" (when reconnecting) | You logged in to a different Threads profile. | Log in to Threads as the profile you're reconnecting. |
In the post editor#
| Message | What it means | What to do |
|---|---|---|
| "You can upload up to 20 files" | A Threads post takes up to 20 photos and videos. | Remove some. |
| "Wrong file format. Please upload JPG, PNG, MP4 or MOV" | Threads takes JPG and PNG photos, MP4 and MOV videos. | Convert the file. |
| "Image size limit: 8MB maximum" / "Video size limit: 1024MB maximum" | The file is too big. | Compress it. |
| "Codec is not supported. For more information please check requirements" | Your browser can't read the video. | Export it again as an H.264 MP4. |
| "You can have up to 500 characters in caption" / "You can have up to 500 characters in first comment" | The text is too long. | Shorten it. |

| Hovering Schedule All shows "Please select accounts for Threads" | Threads is on for this post, but no profile is ticked. | Tick one, or switch Threads off for the post. |
When you schedule#
These come from the same rules, checked again when you schedule or publish:
- "Unable to post because Threads requires link."
- "Unable to post because Threads requires caption or at least 1 media."
- "Unable to post because Threads requires caption for link post."
Open the Threads tab, add what the message asks for, and schedule again.
When a post fails#
Failed posts are listed under Content → Posting Errors. Threads' own messages are shown as Threads wrote them.
| Message | What it means | What to do |
|---|---|---|
| "Threads is temporarily limiting how often this account can post. …" | Threads limited the profile, so Heropost paused publishing to it. | Wait until the time shown, then send the post again with Duplicate Failed. See Limits and holds. |
| "Threads took too long to process video. Eventually, Threads marked it as expired." | Threads didn't finish processing the video within 15 minutes. | Try again with a smaller video, ideally an H.264 MP4 under 5 minutes. |
| "Media was not published due to error. {error}" | Threads couldn't process a photo or video. | Check the file against Threads' rules under Media Requirements, export it again, then send the post again with Duplicate Failed. |
| "Param text must be at most 500 characters long" | The text is over Threads' limit, usually from an automation or an AI tool. | Shorten the text on the Threads tab. |
| "Your subscription does not include Threads" | The profile was connected earlier, but the workspace owner's plan doesn't include Threads (the original Lifetime plan). | Upgrade, or untick Threads in your posts. |
| "Failed to create a comment to Threads post" | The post went out, but the first comment didn't. | Reply to the post on Threads. |
If several posts fail with a message about the access token or session, Threads ended Heropost's access: reconnect the profile.
Failed posts aren't sent again by themselves. After fixing the cause, open the post from Content → Posting Errors and choose ⋮ → Duplicate Failed: you get a draft with only the accounts that failed, ready to schedule. See The Posting Errors page.
Questions#
Does connecting Instagram connect Threads too?
No. Add Threads separately: click your workspace name at the top of Heropost, then Accounts, then Add Profile. Each one is its own account in Heropost.
How does the first comment appear?
As a reply to your post, from your profile, right after the post goes out.
Can I mix photos and videos?
Yes. A Threads post can carry up to 20 photos and videos together, which Threads shows as a carousel.
Why is a recent post missing from Analytics?
Threads reports nothing for a post that has no views or interactions yet, so it appears once it has some. Numbers are refreshed every few hours for new posts, and less often as they age.
Heropost paused my Threads posts. Can I lift the pause?
No. The pause protects the profile while Threads is limiting it. Wait until the time in the message, then send the held posts again with Duplicate Failed and space them out.
