INVALID_TOKEN_HEADER, Trigger: New developers must use the Google Ads API

[ecommerce powerweave]

Hi Team,

I've tried User authorization and generated the Refresh token. Next, I tried to fetch Campaign for AdWords API using 'OAuth 2.0 Client IDs' credentials and TestAccount details but its failing with the error 'INVALID_TOKEN_HEADER (Error: QuotaCheckError.INVALID_TOKEN_HEADER, FieldPath: Trigger: New developers must use the Google Ads API)

The sequence of steps as follows:

1. Obtained credential details from https://console.cloud.google.com/apis.

2. Used above Client ID & Client secret credentials in 'AdWords.Examples.CSharp.OAuth.csproj'->web.config' .

3.Since there is no developer token available in test accounts hence created the developer token by signing in to the manager account and fetched the Developer and Customer token from the API Center (TOOLS > MORE TOOLS > API Center). Set these details on 'web.config' file as mentioned above in step 2.

4. Created Test Account for customer client and linked that to another account. Then added AD Campaign.

5. Tried to get the campaign using these details and got the error below:

• Failed to get campaigns. Exception says "AdWordsApiException: Exception of type 'Google.Api.Ads.AdWords.Lib.AdWordsApiException' was thrown. Customer passed in an invalid token in the header.. (Error: QuotaCheckError.INVALID_TOKEN_HEADER, FieldPath: Trigger: New developers must use the Google Ads API.) "

Please advise on.

Hello,

Thanks for reaching out. Please see this blog post regarding the sunset of the AdWords API. If you have obtained your developer token after April 29, you will not be able to use the AdWords API. Instead, please use the new Google Ads API.

Enable  library in your application Google Ads API - https://console.cloud.google.com/apis/api/googleads.googleapis.com/overview

Hi,

Thank you for reaching out to our API support team.

Can you clarify when the developer token you used for these queries was created? Our team is currently looking into this, but it's possible that, since the AdWords API deprecation notice was announced, limitations have been placed on the usage of the AdWords API for new developer tokens.

Best regards,

Peter Laurence Napa Oliquino Google Ads API Team

Greetings!

In April, we announced the sunset of the AdWords API (https://ads-developers.googleblog.com/2021/04/upgrade-to-google-ads-api-from-adwords.html). In that blog post, we say, "Any developers applying for a new developer token after today will only be given access to the Google Ads API. " You can take a look at the Google Ads API here (https://developers.google.com/google-ads/api/docs/start). You can use the same developer token and OAuth credentials.

Cheers,

Hi,

Our team has now identified the cause of this error. That said, in order to avoid encountering this, you may refer to this guide when using newly created developer tokens.
