### What’s Deeplink Match/Deeplink Attribution?

MMP SDK utilizes deep link parameters to attribute the deeplink to any in-app event.

Deeplink Match/Deeplink Attribution is the attribution method usually used in re-engagement campaigns.

### How does it work?

When an app is opened via a deeplink, it launches immediately if the user has the app installed. Subsequently, the MMP SDK sends a click request to the MMP, including attribution data (e.g., campaign info, click ID), for attribution.

For example:

`appierApp://eventpage1?reftag=cyk3zeoKo1Zvz`

#### Step1

App opens the deeplink by recognizing the deeplink scheme:

**appierApp\://**eventpage1?reftag=cyk3zeoKo1Zvz

#### Step2

App’s deeplink handler deals with path and parameters in the link to open up a specific page or trigger event.

appierApp\://**eventpage1?reftag=abcd12345**

Meanwhile, MMP SDK also deals with parameters in the link to see if there is any attribution info.

In this case, `reftag=abcd12345` is used to attribute the deeplink open event.

#### Step3

MMP SDK sends this attribution info to the MMP server which records the deeplink in-app event as attributed.
