Developer Preview Program

Stay organized with collections Save and categorize content based on your preferences.

You can apply to join the Google Workspace Developer Preview Program to get early access to certain features. Features in developer preview have already completed early development phases, so they're ready for implementation. This program gives you the chance to shape the final stages of feature development with feedback, get pre-release support, and have your integration ready for public use on launch day.

We regularly review new applications to ensure developers meet program requirements. Approved applicants receive confirmation and further information about how to start developing.

Developer Preview Program Terms

(i) I consent to be contacted by Google regarding all current and future features in the program, including in regards to marketing and research opportunities.

(ii) I understand that program features may not be included in public applications prior to the General Availability (GA) announcement.

(iii) By enrolling in the Google Workspace Developer Preview Program, or using Google Workspace APIs, other developer services, and associated software (collectively, "APIs"), I agree to the Google APIs Terms of Service.

(iv) I understand that, for purposes of testing, I may not grant end users access, outside my domain/company, to developer applications that have been built using APIs prior to their GA announcement ("Pre-GA APIs") unless Google specifically states that I can request such permission and such permission has been granted to my Workspace account for that feature. Where permission is granted from publication of Pre-GA APIs, (a) there is no guarantee that such Pre-GA APIs will become GA, (b) such Pre-GA APIs may impact the performance level of developer's applications, and (c) I fully assume the risks associated with sections (a) and (b) of this paragraph.

(v) There may be cases where I can test certain Google features as an end user. I understand that in any such case, the Pre-General Availability Offerings Terms from Section 6 of the Google Workspace Service Specific Terms apply to my use of those Pre-GA Offerings.

(vi) I understand that Google may use any data submitted, stored, sent, or received via any Pre-GA APIs to provide, test, analyze, develop, and improve those APIs in accordance with applicable laws.

(vii) I understand that if I am using the Pre-GA APIs on behalf of a government or regulatory entity (excluding educational institutions), I may only use test or experimental data with Pre-GA APIs and am prohibited from using any "live" or production data in connection with Pre-GA APIs.

(viii) I understand that PRE-GA APIs ARE PROVIDED "AS IS" WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES OR REPRESENTATIONS OF ANY KIND.

(ix) I understand that I should check this application from time to time as I am bound by all updates including updates to the incorporated TOS herein.
