It's possible to set up View-through attribution along with Probabilistic attribution demanded by iOS 14 rules.

Standard VTA flow is described here and Probabilistic attribution setup is here.

When you work with Probabilistic attribution, you cannot store and pass unique impression identifier that is usually passed in Affise via {aimp_id} macro in Impressions Destination URL and received via aimp_id parameter in Postback URL.

In this case, tracking works similar to the tracking based on clicks.

Impressions Destination URL setup

To match an impression received from your affiliate and a conversion received from your advertiser, you need offer and partner identifiers.

Update your Impressions Destination URL with {oid} and {aid} mandatory macros to pass the information about the offer and affiliate to your advertiser.

To pass more information, use the macros listed here, except {aimp_id}.

The link should look like this:

Probabilistic Postback setup

Probabilistic postback is build according to the standard rules described here.

Note to update Affise postback link with mandatory offer_id and pid parameters.

Other parameters can also be added to better match an impression and conversion.

The postback should look like this:

When you receive a conversion based on impression, you can match them by offer and partner identifiers, and by other parameters if you used them.

Differentiate conversions based on clicks and conversions based on impressions

You can track clicks and impressions within one offer, and use common Probabilistic postback to get conversion info. Since mandatory parameters that you pass and get (offer and publisher identifiers) are the same, you won't understand whether your conversion is based on a click or on impression.

The conversions can be differentiated with the help of additional values click_based and imp_based (or your own values), which are obligatory if you want to see what the conversions are based on. Also, you can use any other non-mandatory parameters to get and pass the necessary info.

Follow the steps bellow to set up the tracking:

  1. In the integration with an affiliate:

  • Set up Affise Tracking link.

  • Set up Impressions link.


2. After you get a click or impression, sub1 or sub2 values are recorded in the statistics.

Detailed statistics for clicks:

Custom slice of Statistics for impressions sub values:

3. You need to pass sub values to an advertiser to get them back with the conversion info.

  • Set up Tracking URL taken from your advertiser.

  • Set up Impressions Destination URL.


4. Set up Probabilistic Postback.


When conversions come via this postback, the necessary sub values appear in Affise.

If there is a conversion based on a click, you see the necessary sub1 value in Conversions statistics:
