It depends on the type of tracking link. For tracking links for integrated channels, there is no character limit for parameter values. For tracking links for custom channels, each parameter value has a maximum limit of 128 characters.

Upper and lower case letters, numbers, ., -, and _ are supported.

Other characters that can be used include spaces, %, $, !, [ ], { }, < >, |, and Japanese punctuation. However, note that tracking links with these characters might not work properly.

Characters not mentioned above are not supported.

Yes, when appending parameters to the short link version of a tracking link, the parameters will also be appended to the long link version.

However, note that appending campaign parameters won't have any effect on the tracking link. The appended campaign parameters won't be used for data aggregation.

Let's say, you have the short link version and the long link version of a tracking link like the following.

• Short link version: https://abr.ge/ouocog

• Long link version: https://abr.ge/@your_app/channel?ad_creative=Jeans_Clothes&ad_group=2030_female&campaign=Summer_Sales&og_tag_id=103833519

If you append a campaign parameter (campaign) and a custom parameter (added_param) to the short link version, the same parameters will be automatically appended to the long link version link the following.

• Short link version:

  https://abr.ge/ouocog?campaign=Spring_Sales&added_params=Promotion

• Long link version:

  https://abr.ge/@your_app/channel?ad_creative=Jeans_Clothes&ad_group=2030_female&campaign=Summer_Sales&og_tag_id=103833519&campaign=Spring_Sales&added_params=Promotion

Note that Airbridge won't use the newly appended campaign parameter value, which is "Spring_Sales," for data aggregation. The original campaign parameter value, which is "Summer_Sales" will be used.

Yes, you can. However, the deleted tracking links will be deleted from the list only. Tracking links deleted from the [Link Management] will continue to function normally.

This happens because we cache and store the previous path. It may take up to 10 minutes before the modified path is applied to the tracking link. Check again after about 10 minutes to see whether users are sent to the new path.

The amount of time it takes for the edits to the social share preview to be reflected in the tracking links varies by social media.

If your edits are not reflected even after a sufficient amount of time, use the sharing debugger provided by each social media to debug any issues with the Open Graph tags. If the problem still persists, contact each social media.

No. The QR code can still be used because there is no change in the tracking link itself.

However, you will need to update the QR code if you have modified the campaign parameters, such as the channel, campaign, ad group, or ad creative.
