WhatsApp messages received in Meta are higher than contacts/conversations recorded in ManyChat

Hi team,

I have ManyChat connected to WhatsApp Cloud API and I’m running Click-to-WhatsApp ads from Facebook/Meta.

Here’s the issue:

• Meta Ads Manager reports 134 conversations started.
• WhatsApp Manager shows 163 messages received.
• However, ManyChat only shows around 70 contacts/conversations.

Important notes:

• The WhatsApp number is correctly connected to ManyChat.
• Ads are properly linked to the correct flows.
• Meta only counts conversations when users actually send a message, so this is not a click issue.
• WhatsApp confirms the messages were received.
• This suggests ManyChat is not capturing all incoming WhatsApp messages.

Could you please help me verify:

1. If all incoming webhook events are being received by ManyChat.
2. If there could be a webhook conflict or missing subscription.
3. If there is any known issue with WhatsApp Cloud API message syncing.

Thanks!
