For the basics of tracking links, see the guides below first. * [Understand Tracking Links](/en/guides/understanding-tracking-link) * [Create Tracking Links in the Airbridge Dashboard](/en/guides/creating-tracking-links-on-the-dashboard) ## Tracking link parameters Parameters are key-value pairs, where the key serves as the parameter name. In a tracking link, parameters appear as `parameter_name={parameter_value}`. When a user clicks an ad, the ad channel fills `{parameter_value}` with touchpoint data, and the tracking link delivers it to Airbridge. Tracking link parameters fall into three types by purpose: campaign parameters, Airbridge parameters, and channel parameters. | Parameter type | Key parameters | | ---------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------- | | Campaign parameter | campaign, campaign\_id, ad\_group, ad\_group\_id, ad\_creative, ad\_creative\_id, content, term, term\_id | | Airbridge parameter | ad\_type, tracking\_template\_id, routing\_short\_id, og\_tag\_id, deeplink\_url, fallback\_android, fallback\_ios, fallback\_desktop | | Channel parameter | click\_id, sub\_id, sub\_id\_1, sub\_id\_2, sub\_id\_3, ad\_id, gaid\_raw, ifa\_raw, ip, user\_agent, language | #### Campaign parameters Campaign parameters deliver information about the campaigns you run on ad channels. | Parameter | Description | Filled by | | ---------------- | --------------------------------------------------- | ------------------------ | | campaign | Campaign name (e.g., `campaign=spring_festival`) | Advertiser or ad channel | | campaign\_id | Campaign ID (e.g., `campaign_id=1481`) | Ad channel | | ad\_group | Ad group (e.g., `ad_group=retargeting`) | Advertiser or ad channel | | ad\_group\_id | Ad group ID (e.g., `ad_group_id=1246`) | Advertiser or ad channel | | ad\_creative | Ad creative (e.g., `ad_creative=Jean`) | Advertiser or ad channel | | ad\_creative\_id | Ad creative ID (e.g., `ad_creative_id=129840`) | Ad channel | | content | Ad content (e.g., `content=buy_today`) | Advertiser or ad channel | | term | Search ad keyword (e.g., `term=%EC%95%88%EA%B2%BD`) | Advertiser or ad channel | | term\_id | Search ad keyword ID (e.g., `term_id=3452`) | Ad channel | #### Airbridge parameters Airbridge parameters deliver information such as touchpoint and deep link data for attribution, user redirection, and other functions. | Parameter | Description | Filled by | | ---------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------ | ---------- | | ad\_type | Ad type. Categorized by touchpoint type into impression (view), click (click), or S2S click (server\_to\_server\_click). (e.g., `ad_type=click`) | Advertiser | | tracking\_template\_id | Unique ID of the Airbridge tracking link | Airbridge | | routing\_short\_id | Unique ID of the redirection destination (e.g., `routing_short_id=jx4e`) | Airbridge | | og\_tag\_id | Unique ID of the Open Graph tag | Airbridge | | deeplink\_url | URL that sends users who already have the app installed to a specific app page | Advertiser | | fallback\_android | Overrides the default redirection destination on Android | Advertiser | | fallback\_ios | Overrides the default redirection destination on iOS | Advertiser | | fallback\_desktop | Overrides the default redirection destination on Desktop | Advertiser | #### Channel parameters Channel parameters deliver information about the ad channels where you run campaigns. | Parameter | Description | Filled by | | ---------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------- | | click\_id | Unique ID of the touchpoint determined by the ad channel (e.g., `click_id=12345234`) | Ad channel | | sub\_id | ID for a sub-network or affiliate channel associated with the main ad channel (e.g., `sub_id=356234234`) | Ad channel | | sub\_id\_1, sub\_id\_2, sub\_id\_3 | IDs for sub-networks at different hierarchy levels. Use them in the order of each sub-network's level. The ad channel usually fills these, though some channels let the advertiser pass custom values. | Ad channel | | ad\_id | Advertising ID (ADID) used by the device's operating system, such as GAID on Android or IDFA on iOS | Ad channel | | gaid\_raw | ADID used on Android | Ad channel | | ifa\_raw | ADID used on iOS | Ad channel | | ip | IP address of the device where the S2S click is triggered | Ad channel | | user\_agent | User agent of the device where the S2S click is triggered | Ad channel | | language | Language setting of the device where the tracking link is triggered | Ad channel | #### Example tracking link The following is an example of an ad channel tracking link template. When a user clicks an ad, the ad channel fills macros such as `{{campaign.title}}` and `{{request.id}}` with actual values and delivers them to Airbridge. In this example, demo is a placeholder for your app name and ad\_channel\_example is a placeholder for the channel name. `routing_short_id` and `tracking_template_id` are values Airbridge assigns automatically when the link is created. * https://abr.ge/@demo/ad\_channel\_example?ad\_creative=\{\{creative.title}}\&ad\_creative\_id=\{\{creative.id}}\&ad\_group=\{\{adgroup.title}}\&ad\_group\_id=\{\{adgroup.id}}\&ad\_id=\{\{device.ifa}}\&campaign=\{\{campaign.title}}\&campaign\_id=\{\{campaign.id}}\&click\_id=\{\{request.id}}\&routing\_short\_id=n8jhtp\&source=\{\{mtid}}\&sub\_id=\{\{request.exchange}}\&sub\_id\_1=\{\{publisher.bundle}}\&sub\_id\_2=\{\{request.inventory\_type}}\&sub\_id\_3=\{\{creativegroup.title}}\&tracking\_template\_id=929fcc895e4636e5a83c855a98d867f3\&ad\_type=click | Parameter | Value filled in (channel macro) | Filled by | | ------------------------------------------ | ------------------------------------------------------------------------------- | ---------- | | campaign, campaign\_id | `{{campaign.title}}`, `{{campaign.id}}` | Ad channel | | ad\_group, ad\_group\_id | `{{adgroup.title}}`, `{{adgroup.id}}` | Ad channel | | ad\_creative, ad\_creative\_id | `{{creative.title}}`, `{{creative.id}}` | Ad channel | | ad\_id | `{{device.ifa}}` | Ad channel | | click\_id | `{{request.id}}` | Ad channel | | sub\_id | `{{request.exchange}}` | Ad channel | | sub\_id\_1, sub\_id\_2, sub\_id\_3 | `{{publisher.bundle}}`, `{{request.inventory_type}}`, `{{creativegroup.title}}` | Ad channel | | routing\_short\_id, tracking\_template\_id | Assigned automatically by Airbridge (fixed) | Airbridge | | ad\_type | click (fixed) | Advertiser |
