Campaign Parameters

What characters can be used for campaign parameters?

---

It is strongly recommended to use the following characters.

• 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/Channel → My_Channel)
• Any # in the campaign parameter values are replaced by _. (e.g. ad_group=#MyGroup → ad_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

Is it possible to not use a tracking link and use UTM paramters for attribution?

---

Yes, it is possible for both web and app events. Please see below for details.
