Migrate Your Adwords API Applications to OAuth 2.0 from ClientLogin

Migrate Your Adwords API Applications to OAuth 2.0 from ClientLogin


Are you a developer and using Adwords API in your client applications? Then chances are you may be using ClientLogin to authenticate your client applications.

The problem is support for ClientLogin authentication is going to reach end of life and will be completely removed in June 2014 and will be replaced with OAuth 2.0. If you have already migrated to use OAuth 2.0 authentication then you’re in good shape and don’t have to do anything.

For others, your Adwords app users won’t be able to access MCC(My Client Center; tool to manage multiple Adwords account) account or your Adwords account via the API through ClientLogin since it is deprecated.

OAuth 2.0 is the industry standard to authenticate 3rd party applications without sharing passwords and nowadays pretty much all applications use it. Google Adwords team has written a ClientLogin to OAuth 2.0 migration guide here that’ll help with the migration.
