Messaging limits for Business Messaging API

For a Business Account's non-mutual follow conversations handled via the Business Messaging API, the following messaging limits apply: - Initial 48-hour window: After receiving the first message from a TikTok user, Business Account can send up to 10 messages within the next 48 hours. - Active conversation window: If the TikTok user replies to the Business Account's message, a new interaction window starts. Within 48 hours after each last reply from the TikTok user, the Business Account can send an unlimited number of messages to that user. - Inactive conversation limit: If more than 48 hours have passed since the TikTok user's last reply, the Business Account is limited to sending a maximum of three additional messages. This restriction remains in effect until the TikTok user responds again, which will reactivate the unlimited messaging window for the next 48 hours. - Example flow:
TikTok user sends first message
→ Business Account can send up to 10 messages in 48 hours
→ TikTok user replies
→ Business Account can send unlimited messages in the next 48 hours
→ If TikTok user doesn't reply for over 48 hours
→ Business Account can only send three more messages
→ TikTok user replies again
→ Unlimited messaging window reopens for 48 hours, and additional three more messages after 48 hours until the TikTok user replies again.
