Hi there, We’ve implemented the Webhook integration a while back ( **Cloud Studio** ), and interestingly, we’re missing three headers from the uplink messages for one particular device, which is a very common Browan AQI sensor. For all devices but this one we’re getting all 4 headers just fine (i.e. **x-downlink-apikey** , **x-downlink-push** , **x-downlink-replace** , and **x-tts-domain** ), but for this sensor, we’re only getting one: **x-tts-domain**. What could be going on here? I’ve checked the documentation and there’s no mention of situations in which these headers are omitted, and also I haven’t seen any similar reports. Thanks in advance! All the best, Diego ---

Hi everyone! Just checking if my question maybe wasn’t clear enough? Maybe anybody could shed some light on this issue? Thank you! All the best, Diego
