Google Documents List API Terms of Service
Google will announce if it intends to discontinue or make backwards incompatible changes to this API or Service. Google will use commercially reasonable efforts to continue to operate those Google Documents List API versions and features identified at http://developers.google.com/google-apps/documents-list/documents-list-api-list without these changes until April 20, 2015, unless (as Google determines in its reasonable good faith judgment):
- required by law or third party relationship (including if there is a change in applicable law or relationship), or
- doing so could create a security risk or substantial economic or material technical burden.
The above policy is the "Deprecation Policy."
