.net adwords api 'Failed to get access token for service account'

[otser...@allthingsweb.gr]

Hi,

i use the new adwords api (v201402) and i have trouble downloading reports via api.

I have successfully completed the entire procedure of service account (https://developers.google.com/adwords/api/docs/guides/service-accounts).

I use this configuration:

    <add key="OAuth2Mode" value="SERVICE_ACCOUNT" />

    <add key="OAuth2ServiceAccountEmail" value="x...@developer.gserviceaccount.com" />

    <add key="OAuth2PrnEmail" value="xxx" />

    <add key="OAuth2JwtCertificatePath" value="path-privatekey.p12" />

    <add key="OAuth2JwtCertificatePassword" value="xxx" />

and i have registered the scope successfully

But sometimes (not always) i get this message : "Failed to get access token for service account" 

Can you help me please?

[otser...@allthingsweb.gr]

To be specific i get Failed to get access token for service account.\n{\n  \"error\" : \"invalid_request\"\n}"}
But the weird part is that i get  this message after calling the service for about a minute. Until then no errors are shown and i get my reports correctly.

Any ideas?

Hello,

Are you running a Google Apps domain? In most cases, you should not be using Service Accounts unless you need very specific features like impersonation.

Please see this guide for more details:

Thanks for the reply.

Yes i am running a Google Apps domain. I implemented each step of the procedure correctly i guess as i get some results back. But sometimes i get  Failed to get access token for service account.\n{\n  \"error\" : \"invalid_request\"\n}"}

Do i miss something?

Otherwise is there a way to use the api with <add key="OAuth2Mode" value="APPLICATION" /> without user interaction?

I'm having the same problem with Failed to get access token for service account.\n{\n  \"error\" : \"invalid_request\"\n}"}

I'm using the .net client library. It seems that after retrying several times (more than 5 attempts) it eventually works which is quite unusual.

Hello,

We recommend to either use "Installed application" or "Web application" flows. The former one for the cases when you manage only your accounts (all accounts are linked to a single MCC) and the latter when you manage unlinked 3rd party accounts.

In both cases, user interaction is only required once (per user), to grant the access. Once access is granted you receive a refresh token you can use indefinitely with no further user input required.

Hello,

My problem is that i use the adwords api on various scheduled tasks that user interaction is not possible.

Can you describe me or redirect me to a link that shows clearly how to use adwords api with no user interaction? Is this even possible?

Thanks

[Danial Klimkin]

Hello,

As mentioned above, user interaction is required only once, user needs to indicate he / she agrees the account will be managed by your application.

When this is done you receive a refresh token which can be used in your scheduled tasks with no additional user interaction required. Please see:

Hi Danial

I've managed to eradicate 'Failed to get access token for service account.{  "error" : "invalid_request"}"}' for now by sharing the "AdWordsUser" object between all threads in my application.

Does that mean the error can relate to throttling?

Cheers

David

Hello David,

There is definitely a limit on how often you can request a new refresh / access tokens. It's recommended to re-share them between threads / services.
