Google Ads API Client Library for Golang

This library provides a Golang client for the Google Ads API. It's fully generated from the googleapis repository. More information on the generation process can be found here.

Although this project isn't official, we deem it as low-risk due to its maturity and our two years of using it in production. However, always consult the sunset schedule of the Google Ads API.

Features

• Full support for Google Ads API.
• Source code generated from the official googleapis repository.
• Support for GRPC and HTTP calls using protojson.
• Although we won't regularly update this based on the official repository, we continually maintain it. Update frequency depends on our needs but usually occurs a month after the official release.

Version support

Requirements

• Go 1.20.
• Familiarize yourself with the OAuth2 guide.
• If needed, obtain a developer token.

Installation

$ go get github.com/shenzhencenter/google-ads-pb

Getting started

1. Set your environment variables.

$ export ACCESS_TOKEN=<your access token>
$ export DEVELOPER_TOKEN=<your developer token>
$ export CUSTOMER_ID=<your customer id>

1. Establish a GRPC connection.

ctx := context.Background()

headers := metadata.Pairs(
  "authorization", "Bearer "+os.Getenv("ACCESS_TOKEN"),
  "developer-token", os.Getenv("DEVELOPER_TOKEN"),
  "login-customer-id", os.Getenv("CUSTOMER_ID"),
)
ctx = metadata.NewOutgoingContext(ctx, headers)

cred := grpc.WithTransportCredentials(credentials.NewClientTLSFromCert(nil, ""))
conn, err := grpc.Dial("googleads.googleapis.com:443", cred)
if err != nil {
  panic(err)
}
defer conn.Close()

1. Start making calls.

customerServiceClient := services.NewCustomerServiceClient(conn)
accessibleCustomers, err := customerServiceClient.ListAccessibleCustomers(
  ctx,
  &services.ListAccessibleCustomersRequest{},
)
if err != nil {
  panic(err)
}

for _, customer := range accessibleCustomers.ResourceNames {
  fmt.Println("ResourceName: " + customer)
}

You can also make HTTP calls using protojson, though it isn't recommended.

req := services.ListAccessibleCustomersRequest{}
requestBody, err := protojson.Marshal(&req)
if err != nil {
  panic(err)
}
request, err := http.NewRequest("GET", "https://googleads.googleapis.com/v14/customers:listAccessibleCustomers", bytes.NewBuffer(requestBody))
if err != nil {
  panic(err)
}
header := make(http.Header)
header.Set("content-type", "application/json")
header.Set("authorization", os.Getenv("ACCESS_TOKEN"))
header.Set("developer-token", os.Getenv("DEVELOPER_TOKEN"))
request.Header = header
client := &http.Client{}
response, err := client.Do(request)
if err != nil {
  panic(err)
}
defer response.Body.Close()
var responseBody []byte
if responseBody, err = io.ReadAll(response.Body); err != nil {
  panic(err)
}
listAccessibleCustomersResponse := new(services.ListAccessibleCustomersResponse)
if err := protojson.Unmarshal(response, listAccessibleCustomersResponse); err != nil {
  panic(err)
}
for _, customer := range listAccessibleCustomersResponse.ResourceNames {
  fmt.Println("ResourceName: " + customer)
}
