1# Google Ads API 2 3This folder contains the [protocol 4buffer](https://developers.google.com/protocol-buffers/) definitions and 5**experimental** build files (see below) for the [Google Ads 6API](https://developers.google.com/google-ads/api/). 7 8To use this 9API, we encourage you to take a look at our [official client 10libraries](https://developers.google.com/google-ads/api/docs/client-libs) for 11Java, Ruby, PHP, Python or .NET. Refer to the 12[Quickstart](https://developers.google.com/google-ads/api/docs/first-call/overview) 13to learn how to make your first API call. 14 15To develop in a programming language without an official client library, refer 16to the [API Concepts 17Guide](https://developers.google.com/google-ads/api/docs/concepts/overview) and 18consult these protocol buffer definitions as a reference when constructing API 19requests. 20 21Use [the official Google Ads API 22forum](https://groups.google.com/d/forum/adwords-api) to request an official 23client library in another programming language, report bugs, request new 24features in the Google Ads API, or provide feedback. 25 26## Build files (experimental) 27 28> **IMPORTANT** The Bazel build files are **experimental**. The structure and 29> content of the Bazel packages are subject to change, and the resulting 30> generated API clients are not officially supported Google products. 31 32The [Bazel](https://bazel.build/) build files contain targets for building 33**generated API clients (GAPICs)** from the Google Ads API protocol buffer 34descriptors. Our [officially supported 35client libraries](https://developers.google.com/google-ads/api/docs/client-libs) 36are built upon these GAPIC artifacts, but add significant performance and 37usability enhancements. Thus, we strongly recommend using an official 38client library. 39 40However, developers looking to understand the internals of the API's client 41libraries or build their own custom [gRPC](https://grpc.io/)-based clients can 42use these build files as reference points. 43 44For details on using these files, see the 45[Bazel section](https://github.com/googleapis/googleapis#bazel) of the 46repository's main 47[README.md](https://github.com/googleapis/googleapis/blob/master/README.md). 48
