How can I prevent WhatsApp API status updates from triggering n8n webhooks?

Hi everyone,
I’m using n8n to handle a webhook that receives messages from the WhatsApp API. However, the webhook is triggered not only for the initial message but also for three additional status update requests that unnecessarily increase execution costs. I’ve already implemented a function node to filter out status updates after the webhook is triggered, but this approach does not prevent the workflow from starting in the first place.
Is there a way to configure the webhook node or n8n in general so that these status updates don’t trigger the workflow at all? Alternatively, is there another strategy to avoid these extra executions and minimize costs?
Any advice or suggestions would be greatly appreciated!
- n8n version: 1.64.3
- Database (default: SQLite): MySQL
- n8n EXECUTIONS_PROCESS setting: IDK
- Running n8n via: Cloud
- Operating system: Windows

Based on the current WhatsApp Trigger documentation, n8n doesn’t provide a built‑in way to prevent unwanted event types (like status update events) from triggering your workflow. In other words, the WhatsApp API sends all event types—including message status updates—to your webhook, and the node will trigger for every request that arrives.
Some strategies you might consider are:
-
Pre‑workflow filtering:
Since the WhatsApp Trigger node cannot filter events internally, you need to filter out unwanted events early in your workflow (using a Function or IF node). Although this doesn’t stop the workflow from triggering, it reduces the processing by exiting quickly. -
External filtering:
If possible, configure the webhook on the WhatsApp API side (or through an intermediary such as a custom proxy) to only forward original messages rather than status updates. This way, the extra calls won’t even reach your n8n instance. -
Separate webhooks:
If WhatsApp provided different endpoints or settings per event type, using separate webhook URLs might help—although as of now, there isn’t a documented option for the WhatsApp Trigger node to do this.
Unfortunately, as things stand the most reliable solution is to filter the events within your workflow as early as possible so that the unnecessary additional processing is kept minimal.
If WhatsApp updates its API or n8n releases additional configuration options for the node in the future, that may allow for a cleaner separation of event types. Until then, adjusting your workflow or the webhook route externally are your best strategies to minimize cost and execution overhead.
