Go to the Traffic sources section ➜ Create ➜ Create custom traffic source.

In the Parameters section, specify the name exid and the macro {exid} for the External ID parameter.

For more accurate analytics, you can optionally pass the deposit amount and transaction currency.

Parameters:

• payout – deposit amount
• currency – transaction currency (e.g., USD, EUR)

Example postback with payout and currency:

https://tools.zm.app/pb/?exid=abc12345&action=dep&payout=1.05¤cy=EUR

Go to Passing conversion info to traffic source and select Traffic source postback URL per event type.

Set up postbacks for conversion statuses:

• For registration, select download:

  https://tools.zm.app/pb/?exid={externalid}&action=reg
  

• For deposit, select sell:

  https://tools.zm.app/pb/?exid={externalid}&action=dep
  

Now, Voluum will send data to ZM apps and track conversions. Make sure that all parameters are passed correctly by testing the traffic before launching.
