The Webhook integration format does not contains the gateway list. This can impact running applications like mapper and tracking systems using triangulation.

- Is that because of the bridge between v2 and v3 ? will it be back once the gateways will be migrated to v3?

- According to the documentation : [Data Formats | The Things Stack for LoRaWAN](https://www.thethingsindustries.com/docs/reference/data-formats/)  
It should be here but V3 devices over V2 expose only gateway\_id : “packetbroker”

That is correct, anything routed via a V2 gateway will appear as “packetbroker” - there are various discussions else where on this topic as yes, it does rather break the TTN Mapper.

As I understand it, it’s not a trivial change so the engineering impact needs to be figured out.

Ok, good to know.  
Thank you for the details
