If the application app needs to access multi-mic, it needs to provide a deep link to record and track multi-mic traffic information. Advertisers can provide deeplink information by implementing the deeplink acquisition interface, and can also inform Duomai of the splicing method evoked by the link, and Duomai will do the splicing by itself

For example, the promotion link: devapp://index/cps?union=duomai&euid=103255212&scene=goods&id=3451233

The link provides 4 parameters

• union = duomai identifies the promotion channel as duomai
• euid = 103255212 Provides the identification parameters passed in by channel customization, which is used for the channel to distinguish its own sub-channels
• scene = goods means the landing scene is a product page
• id = 3451233 The specific id of the product

Duomai alliance parameters

The following are the parameters spliced by the alliance after the link of the advertiser. The advertiser can decide the name of the parameter. If you want to pass in the product id, activity id and other information, the advertiser needs to provide the product material interface and activity material interface separately.

Parameter name	Required	Example	Description
