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.

Requirements

• Go 1.21.
• Familiarize yourself with the OAuth2 guide.
• If needed, obtain a developer token.

Installation

$ go get github.com/Optable/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>

2. 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()

3. 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)
}

Note for the updating process

1. Find the version number in this folder.
2. Run git checkout -b bump-to-v15 (change the version accordingly).
3. Run make generate to generate the code.
4. It will prompt you to enter the version number. Enter the version number you found in step 1, without the v. Example: For v15, enter 15.
5. Once the process is done, it should have modified some files in /clients and /protogen
6. Modify this readme.md to add the version number to the table with the next tag (ref: https://developers.google.com/google-ads/api/docs/sunset-dates)
7. Create a PR with the changes against https://github.com/Optable/google-ads-pb/tree/main.
8. Create a tag with the PR merged in step 7. git tag -a v1.1.0 -m "update to v15"
9. Mark the pushed tag as Latest release in GitHub: https://github.com/Optable/google-ads-pb/releases/edit/v1.1.0
10. Publish the release on Golang GOPROXY=proxy.golang.org go list -m github.com/Optable/[email protected]
