post https://us.identity.api.liveramp.com/v1/batch/match
To make a batch request call, make a POST call to https://us.identity.api.liveramp.com/v1/batch/match and pass in a JSON array of URL strings constructed in the same way as a single transaction call. Start each string with "/entities/match?" and then include the parameters for each request, with each parameter separated with an ampersand character ("&").
You can pass up to 1,000 URL strings in a single batch call.
