<Info>
  **Note**

  This guide lists the parameters you can add to your tracking links. For the basics of tracking links, see the guides below first.

## 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.

| <span style={{ display: 'inline-block', minWidth: '160px' }}>Parameter type</span> | 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 |

#### 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`). Included only in tracking links created before Oct 14, 2026. In tracking links created on or after Oct 14, 2026, `tracking_template_id` takes over its role. | Airbridge |
| og\_tag\_id | Unique ID of the Open Graph tag. Included only in tracking links created before Oct 14, 2026. In tracking links created on or after Oct 14, 2026, `tracking_template_id` takes over its role. | 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 |

| 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`
