your preferences while you can use google cloud apis directly by making raw requests to the server client libraries provide simplifications that significantly reduce the amount of code you need to write this document explains methods for interacting with google cloud apis cloud client libraries recommended google api client libraries firebase mobile your own client code to find client library information for a specific google cloud product see the client libraries section within that product s documentation to view all cloud client libraries often organized by supported language see cloud client libraries cloud client libraries cloud client libraries are the recommended option for accessing cloud apis programmatically where available cloud client libraries use the latest client library model and provide idiomatic code in each language to make google cloud apis intuitive to use provide a consistent style across client libraries to simplify working with multiple google cloud services handle all the low level details of communication with the server including authenticating with google can be installed using familiar package management tools such as npm and pip in some cases give you performance benefits by using grpc for more information see grpc apis the installation instructions and reference materials for cloud client libraries depend on the specific google cloud api and the programming language you are using to find this information see the documentation for the specific google cloud product most products include a client libraries section in their documentation which provides language specific guidance installation steps and links to the detailed api reference you can find the documentation for a specific product by browsing the google cloud api library try it for yourself if you re new to google cloud create an account to evaluate how our products perform in real world scenarios new customers also get 300 in free credits to run test and deploy workloads get started for free google api client libraries if cloud client libraries aren t available for your preferred language for a specific api you can use the google api client libraries these are an earlier type of client library provided by google you might also use these libraries if you re upgrading a project that already uses them these libraries provide access to the api s rest interface only grpc is not supported have auto generated interface code that might not be as idiomatic as the cloud client libraries handle all the low level details of communication with the server including authenticating with google can be installed using familiar package management tools such as npm and pip use the firebase development platform firebase is google s platform of services designed to support your entire app development lifecycle it provides cross platform sdks to help you and ai agents build and run apps for apple platforms android the web flutter unity and c for information on the supported google cloud apis and how to get started with firebase see the firebase documentation use your own client code if you re an experienced developer and cloud client libraries don t meet your specific needs you can write your own custom code to access the service s lower level service apis directly rest http apis all google cloud apis expose a json rest interface if you need to write your own custom code to directly access the rest api using a third party http client library you can find out more about how google cloud apis work with different http versions and implementations in the http guidelines grpc apis grpc is a language neutral platform neutral open source remote procedure call rpc system initially developed at google you can find out more at grpc io grpc enabled google cloud apis generally have both rest and rpc interfaces so rather than just using json over http to talk to the rest interface grpc enabled api clients can also use protocol buffers and grpc over http2 to talk to the rpc interface you can find out if an api is grpc enabled by checking its apis and reference section if a google cloud api is grpc enabled you can generate your own grpc client libraries for it in any grpc supported language to do this you ll need the api s protocol buffers service definition typically available from the repository on github you can then follow the instructions for your preferred language on grpc io to generate and use your client if you don t want to generate your own grpc code you can still benefit from grpc a growing number of cloud client libraries for grpc enabled apis use grpc under the hood to communicate with google s servers this is significantly more efficient in terms of throughput and cpu usage accessing an api using grpc can increase throughput per cpu by as much as a factor of 10 compared to the json rest api google plans to upgrade as many cloud client libraries as possible to grpc in the meantime you ll still get all the other advantages of google s client library code other ways to access cloud apis if you don t want to access an api programmatically you can access some of the same functionality using the tools
