Limitations

"AI Generated" label

Meta does not expose the "AI Generated" content label through their API. You cannot add this label to Facebook posts published through Blotato or any third-party tool.

---

Custom cover images for videos

Facebook does not support custom cover images for video posts via API. You cannot set a custom thumbnail when publishing Facebook videos through Blotato or any third-party tool.

---

"Published by" label

The "Published by [App Name]" label appears on Facebook posts when published via any third-party app. Facebook does not allow you to remove this label because it is part of their transparency policy.

---

Regular feed video posts

Facebook no longer supports regular feed video posts through the API. All Facebook videos publish as Reels -- see Facebook Reel requirements.

---

One Blotato account per Facebook account

You can connect multiple Facebook accounts to a single Blotato account. However, the same Facebook account cannot be connected to more than one Blotato account at the same time.

If you connect Facebook Account X to Blotato Account A, then connect Facebook Account X to Blotato Account B, the token in Blotato Account A becomes invalid. Reconnecting in Blotato Account A then breaks Blotato Account B.

This causes intermittent errors like:

• Could not upload video to Facebook: There was a problem uploading your video file

Fix: Connect each Facebook account to only ONE Blotato account. To manage multiple Facebook Pages owned by the same Facebook user, connect all of them inside a single Blotato workspace.

25 posts per 24h per Page

Blotato limits Facebook publishing to 25 posts per 24 hours per Page. Each Page has its own independent limit, so posts to one Page do not count against another.

Example: 3 Facebook Pages connected through the same Facebook login each publish up to 25 posts in a 24-hour window, for 75 posts total across the 3 Pages.

Facebook also recommends staying under 5 posts per day per Page for organic reach.

Direct messages and DM automations

Messaging works on your connected Facebook Pages, not on personal profiles or Groups. Facebook sets the rules below. Blotato passes them through, so a message outside an allowed window fails.

Who you reach, and when

• You can only reply within 24 hours of the person's last message to the Page.

• You may send one private reply per comment, within 7 days of the comment. A comment that already received a private reply, through Blotato or another tool, rejects the second reply.

• Cold outreach is not supported. Facebook does not let a third-party tool message someone who never contacted your Page.

• Every Facebook message and automation needs the pageId of the Page it sends from. See List Subaccounts.

Message length

Facebook messages are limited to 2000 characters. With buttons attached, the limit drops to 640 characters.

Buttons and quick replies

Limit	Value
Buttons per message	3
Quick-reply chips per message	13
Button or chip label	20 characters
Postback or chip payload	1000 characters
Message text with buttons	640 characters

• Buttons and quick replies are mutually exclusive. A message carries one or the other.

• Facebook supports web_url and postback buttons. Phone buttons are not supported.

• Quick-reply chips disappear once the person taps one or types their own message.

• Blotato subscribes your Page to the postback webhook when you connect it. If you connected your Page before buttons were launched, reconnect to start receiving postback events.

See Buttons and Quick Replies.

DM automations

• A comment trigger answers with a private reply, so the 7-day and one-per-comment rules apply.

• A message trigger answers within the 24-hour window.

• Automation buttons are link buttons only. For postback buttons or quick replies, send the message yourself.

• Per-post targeting uses a Blotato post ID, so it works on posts published through Blotato. For a post published elsewhere, watch any post and match on keywords.

See DM Automations.

Not supported

• Messaging from a personal Facebook profile or a Facebook Group.

• Reading messages older than 45 days. Blotato retains messages for 45 days and does not backfill.
