**Problem**
When a WhatsApp conversation started with a media message, the
conversation created webhook would sometimes fire before the message and
its relationships were fully committed to the database. This resulted in
the message being missing
from the webhook payload, breaking external automations that rely on
this field.
**Solution**
Added `ActiveRecord::Base.transaction` wrapper around the core message
processing operations in `Whatsapp::IncomingMessageBaseService` to
ensure atomic execution:
- `set_conversation` (creates conversation)
- `create_messages` (creates message with account_id)
- `clear_message_source_id_from_redis` (cleanup)
Now the webhook only triggers after all related data is fully persisted,
guaranteeing message availability.
Currently, we do not support reactions, ephemeral messages, or the request_welcome event for the WhatsApp channel. However, if this is the first event we receive in Chatwoot (i.e., there is no previous conversation or contact in Chatwoot), it will create a contact and a conversation without any messages. This confuses our customer, as it may appear that Chatwoot has missed some messages. There are multiple cases where this might be the first event we receive in Chatwoot. One quick example is when the user has sent an outbound campaign from another tool and their customers reacted to the message.
Another event like this is request_welcome event. WhatsApp has a concept for welcome messages. You can send an outbound message even though the user has not send a message. You can receive notifications through a webhook whenever a WhatsApp user initiates a chat with you for the first time. (Read the Welcome message section: https://developers.facebook.com/docs/whatsapp/cloud-api/phone-numbers/conversational-components/ ). Although this can help the business send a pro-active message to the user, we don't have it scoped in our feature set. For now, I'm ignoring this event.
