For conversations through Business Messaging API between a TikTok account and a user who do not follow each other mutually, the following limits apply to messages sent from the TikTok account to the user.

The first 48 hours

After receiving the user’s first message, the TikTok account can send them up to 10 messages within the next 48 hours.

Active conversations

If the user replies to a message from the TikTok account, a new interaction window opens. The TikTok account can send an unlimited number of messages for 48 hours after the user’s most recent reply. Each new reply from the user restarts this 48-hour window.

Inactive conversations

If more than 48 hours have passed since the user’s last reply, the TikTok account can send no more than three additional messages. This limit remains in effect until the user’s next reply.

A reply from the user opens another 48-hour window for unlimited messaging. Once that window ends, if the user has not replied again, the account can send no more than three additional messages until the user’s next reply.
