Failed to send Downlink

Hello everybody,

I’m trying to send a downlink to my device, but I noticed that in the analysis log the following message appears:

“message”:“Missing Authorization Optional Parameters”

Does this have to do with the account token?

Hi @henrique.santos

You need to check the TagoIO documentation on the network you’re using. Usually it is requested for you to edit the Authorization you created under with additional information on “Additional Parameters” field.
