Hi Eduardo, For my answers to your questions, kindly refer below :
1) There is something that we can do only using AWQL (That is impossible using others services methods)? The AWQL query can be used in both the reports and in the services of the AdWords API. For the services, they are usually used when the .query() method is used instead of the .get() method. For more information regarding AWQL, you may refer to this discussion <https://developers.google.com/adwords/api/docs/guides/awql#using_awql_in_service_calls> . 2) The AWQL is exaclty equals to equivalent service call without AWQL considering the HTTP request/response? As mentioned in my earlier answer, the AWQL can be used in services when developers opt to use the .query() method. If I misunderstood your point, please correct me with more details. 3) AWQL is more efficient than alternatives methods to query? AWQL could be considered more efficient as it requires less coding. Depending on the developer, it can be an alternative that they can utilize apart from the Selector fields when using the AdWords API services.
