SKAdNetwork Integration Guide

This guide is intended to share how Airbridge and its partnered ad networks can be integrated with iOS's new SKAdNetwork system. The integration enables Airbridge to receive attribution results from publishers, and Ad Networks can get the advertiser's decoded conversion values configured in Airbridge by using the SKAN conversion value configuration API.

SkAdNetwork Workflow

---

SKAdNetwork attribution data must go through the following three steps to be properly processed and delivered to the advertiser as final aggregated results.

1. iOS Device → Ad Network Postback (Developed by the Advertiser)
2. Ad Network → Airbridge
3. Airbridge → Ad Network Postback

Ad Network → Airbridge Postback

---

The ad network should forward SKAdNetwork postbacks to Airbridge using the Airbridge SKAN Postback API. From the below table, parameters with "SKAdNetwork Postback" as their source should be sent as-is. The parameters with "Ad Network" as their source are parameters that the ad network derives from the SKAdNetwork postback information and sends to Airbridge for a more in-depth analysis.

Option 1. POST Method

The Ad Network receives SKAdNetwork postbacks from a device and then forwards it to Airbridge using the POST method.

HTTP Protocol

Method	POST
Endpoint	https://postback.airbridge.io/skadnetwork/v1
Content-Type	application/json
Response	200: OK 400: Validation Error

When forwarding postbacks to Airbridge, the following information needs to be included in the POST Body. (See below table for details)

Mandatory:

• All information included in the SKAdNetwork Postback
• Attributed channel name (attributed-channel)
• IP address received from the device
• The timestamp of the postback sent from the iOS device

Optional:

• Campaign Parameters

Example

cURL

curl --location --request POST 'https://postback.airbridge.io/skadnetwork/v1' \
--header 'Content-type: application/json' \
--data-raw '{
    "version":"2.0",
    "ad-network-id": "abcabcabc.skadnetwork",
    "campaign-id": 99,
    "transaction-id": "68eb3d91-15f5-44ee-9267-25c7655c20b6",
    "app-id": 888707086,
    "attribution-signature": "MDYCGQCsQ4y8d4BlYU9b8Qb9BPWPi+ixk/OiRysCGQDZZ8fpJnuqs9my8iSQVbJO/oU1AXUROYU=",
    "redownload": false,
    "source-app-id": 888707074,
    "conversion-value": 63,
    "attributed-channel": "adnetwork_abc",
    "attributed-campaign": "test_campaign",
    "attributed-campaign-id": "test_campaign_id",
    "ip": "192.0.2.0",
    "timestamp": 1607678183995
}'

Option 2. 307 Redirect

The Ad Network receives SKAdNetwork postbacks from a device and then responds with a 307 redirect. This will request the device to send SKAdNetwork postbacks to Airbridge directly.

HTTP Protocol

Method	307 Redirect
Endpoint	https://postback.airbridge.io/skadnetwork/v1
Response	200: OK 400: Validation Error

When configuring the redirect URL, the following information needs to be appended to GET Parameters. (See below table for details)

Mandatory:

• Attributed channel name (attributed-channel)

Optional:

• Campaign parameters

Parameter	Required	Description	Source
attributed-channel	true	Attributed Channel (Registered Name on Airbridge)	Ad Network
attributed-campaign	false	Attributed Campaign	Ad Network
attributed-campaign-id	false	Attributed Campaign ID	Ad Network
attributed-ad-group	false	Attributed Ad Group	Ad Network
attributed-ad-group-id	false	Attributed Ad Group ID	Ad Network
attributed-ad-creative	false	Attributed Ad Creative	Ad Network
attributed-ad-creative-id	false	Attributed Ad Creative ID	Ad Network
attributed-sub-publisher	false	Attributed Sub Publisher	Ad Network
attributed-sub-sub-publisher-1	false	Attributed Sub Sub Publisher 1	Ad Network
attributed-sub-sub-publisher-2	false	Attributed Sub Sub Publisher 2	Ad Network
attributed-sub-sub-publisher-3	false	Attributed Sub Sub Publisher 3	Ad Network

Example

https://postback.airbridge.io/skadnetwork/v1?attributed-channel=adnetwork_abc&attributed-campaign=test_campaign&attributed-campaign-id=test_campaign_id

Checklist for Ad Networks

• Please make sure you get a 200 response when you send the above parameters to Airbridge (postback.airbridge.io). The attribution-signature parameter my be excluded when sending postbacks for testing purposes.
• Note that depending on the conversion-value parameter's value, the subsequent postback request from Airbridge may differ.

Airbridge → Ad Network

• response_format

📘

Checklist for Ad Network

api_key and response_format are unique values per Ad Network. Please contact the Airbridge Platform team to receive yours.

Option 2. Decoded SKAdNetwork Postback

Airbridge decodes the conversion values transferred by the ad network, processes it into finalized attribution information, and sends the postback back to the ad network. If you wish to proceed with this option, please contact the Airbridge Platform Team.
