JSON RPC on internal google ad manager API

[Bruno Caruso]

hi everyone,

i'm trying to create custom pricing rules on Google Ad Manager programatically, but the public api doesn't have a CRUD for pricing rules implemented yet, so i'm looking for another ways.

i tried to Inspect Element on Google Ad Manager webapp (admanager.google.com) when i'm saving a custom pricing rules and the app makes a call to a google endpoint (i think it's internal because isn't documented and only interacts with the webapp), the problem is the data that is sending to the endpoint, i think is a JSON-RPC but the keys are strings with numbers , i don't understand the keys, is this encoded or codified? any way to solve?

I attach the endpoint URL here: https://admanager.google.com/dfp/v2/exchange/rpc/PricingRuleService?methodName=createPricingRule

And the request body here: 

{ "method": "createPricingRule", "params": { "2": { - Pastebin.com

Thanks

Regards
