Hello,
I am trying to upload offline conversions with the Google Ads API.
We are using Ruby 2.4, and we have no plans to update the version, so we cannot use the client library.
Therefore, I would like to send an API request via REST and realize an offline conversion upload.
In this case, what value should the request include?
The campaign has been acquired and other mutants have been verified, and the OAuth client information is ready.
I would like advice on how to pass information and conversion data that should be included in the request header.
