Read Query Param by Key

Goal

Extract a specific query parameter value from the incoming link using queryKeys + queryValues.

Actions Used

• DeepLinkServicesOnUniversalLinkOpen or DeepLinkServicesOnCustomSchemeUrlOpen (listener, persistent)

• DeepLinkServicesGetUniversalLinkResult or DeepLinkServicesGetCustomSchemeResult (extractor)

Variables Needed

• queryKeys (Array: String)

• queryValues (Array: String)

• value (String) (example: campaignId / token)

Implementation Steps

1. On listener receivedEvent, call the matching Get*Result action to populate queryKeys and queryValues.

2. Find the parameter:

   • Use PlayMaker Array actions to loop i = 0..queryKeys.Length-1

   • If queryKeys[i] == "campaign" then set value = queryValues[i]

Example URLs

• Universal: https://game.com/promo?campaign=summer2024

• Custom scheme: myapp://oauth-callback?token=xyz

Notes

queryKeys and queryValues are parallel arrays; use the same index for both.
