Automatic Events API
Updated: Nov 18, 2025
Business customers who access Embedded Signup can opt in to automatic event identification:

If a business customer opts in, Meta use a combination of regex and natural language processing to analyze the customer’s new message threads originating from Click-to-WhatsApp ads. If our analysis determines that a lead gen or purchase event occurred, an automatic_events webhook is triggered, describing the event. You can then report the event for the customer using the Conversions API so the customer can use it on a Meta surface (in 2026, see Limitations below).
To learn more about how this feature works, see these additional resources.
