  • Uppercase and lowercase letters

  • Numbers

  • _and -

For custom channels, it is strongly recommended to use the following characters.

  • Lowercase letters

  • Numbers

  • _

Are there length limitations for campaign parameters?


Yes, 256 characters per campaign parameter.

The campaign parameter is different from what I created.

  • Any /in channel names are replaced by_(e.g. My/ChannelMy_Channel)

  • Any #in the campaign parameter values are replaced by _. (e.g. ad_group=#MyGroupad_group=_MyGroup)

Why do I see a $$default$$ channel in my reports?


Airbridge tracking links follows a https://abr.ge/@{app_name}/{channel}?{campaign_parameter} format. If channel is empty when the tracking link is clicked, $$default$$ is shown as its value.e.g. Campaign parameter data collected when clicking on https://abr.ge/@airbridge_demo?campaign=abc.

  • channel: $$default$$

  • campaign:abc
