Im building an app with google ads api using a *service account* auth flow
(server to server). The problem - the auth part is not working...
*Sample of the request:*
```
request({ 'method': 'GET', 'url':
'https://googleads.googleapis.com/v6/customers/XXXXXXXX', 'headers': {
'Authorization': 'Bearer XXXXXXXX', 'developer-token': 'XXXXXXXX',
'Content-Type': 'application/json' } })
```
or
curl --location --request GET
'https://googleads.googleapis.com/v6/customers/XXXXXXXX' \ --header
'Authorization: Bearer XXXXXXXX' \ --header 'developer-token: XXXXXXXX' \
--header 'Content-Type: application/json' [ERROR] Response from google ads
api:{ "code": 401, "message": "Request had invalid authentication
credentials. Expected OAuth 2 access token, login cookie or other valid
authentication credential. See
https://developers.google.com/identity/sign-in/web/devconsole-project.";,
"status": "UNAUTHENTICATED" }
*[ERROR] Response from google ads api:*{ "code": 401, "message": "Request
had invalid authentication credentials. Expected OAuth 2 access token,
login cookie or other valid authentication credential. See
https://developers.google.com/identity/sign-in/web/devconsole-project.";,
"status": "UNAUTHENTICATED" }
I cant seem to find out why Im getting this authentication error.
What I have tried:
1. Following this guide step by step ->
https://developers.google.com/google-ads/api/docs/oauth/service-accounts
2. Using the python library ->
https://github.com/googleads/googleads-python-lib
3. Using the google ads API with REST (no library)
Whatever method / library I try, it results in the same error.
Created a google ads manager account
- Generated a valid developer token for that account
- Created project in Google cloud platform
- Opened a service account inside the project
- Created a private key for the service account
- Enabled domain-wide delegation for the service account
- Granting impersonation abilities in the G Suite domain for this scope:
*https://www.googleapis.com/auth/adwords
<https://www.googleapis.com/auth/adwords>*
- Using a g-suite domain
- Generated the *access token* with the key json file.
- Made the request to *google ads api* from localhost and also from the
web-app (which matches the g-suite domain). Both of them give me the same
401 error.
*I am surely missing something, but am not sure what it is..*
Will be super grateful if someone can share a solution!! thanks champs 👍
