Product Review Guidelines

When you create a client with the Nest Developer program, we'll allocate your client with a limit of 50 unique user tokens. When you hit this limit, you'll need to submit your product to Nest for review and approval to obtain access to more unique user tokens. Products submitted for review should be production quality and ready for launch. Make sure that you provide complete delivery and testing instructions when requesting any review.

1. Functionality

1.1. Products that do not use the official Nest API will be rejected.
1.2. Products that crash will be rejected.
1.3. Products that exhibit user-visible bugs with significant functional impact will be rejected.
1.4. Products that do not provide users with clear error messaging when actions fail, describing the reason for failure, will be rejected.
1.5. Products that do not provide error handling, including rate limiting, will be rejected.
1.6. Products that make bundled calls, requesting several changes simultaneously, may be rejected because bundled calls can cause unexpected behavior.
1.7. Products that do not work with Nest, as described by the developer will be rejected.
1.8. Products that include undocumented or hidden features inconsistent with the description of the product, or the permissions requested, will be rejected.
1.9. Products that are "demo," "trial," or "test" versions will be rejected. Beta apps will be considered. Products that support multiple platforms (for example, iOS, Android, and a web site) should submit all supported platforms at the time of review. Products that do not submit all supported platforms for review may be rejected.
1.10. Products that are not useful or unique, or do not provide any lasting value, such as providing a more complete view of a user's home or added functionality apart from what Nest provides, may be rejected.
1.11. Products that are primarily marketing materials or advertisements with no additional value to users will be rejected.
1.12. Products that provide incorrect or other inaccurate device data will be rejected.
1.13. Products that do not pass Nest Product Review after multiple attempts may be rejected, removed from the Works with Nest Developer Program if the product was previously approved, and may be prohibited from making future submissions.
1.14. Products that retain (by any medium or mechanism) Customer Data received from the Nest API beyond 10 trailing days from the date when the data is received and stored will be rejected (see III. Prohibitions - 2).
1.15. Products that share Customer Data with third parties without consent from Nest will be rejected (see III. Prohibitions - 3).
1.16. Products that allow simultaneous control of Nest devices across multiple Nest accounts may be rejected (see III. Prohibitions - 4).
1.17. Products that perform demand response or other energy management programs will be rejected (see III. Prohibitions - 5).

1.19. Products that evaluate users or their property, individually or in aggregate for insurance or other financial products and services, will be rejected (see III. Prohibitions - 7).
1.20. Products that breach the terms and conditions governing the use of any Nest product or service will be rejected (see III. Prohibitions - 8). 1.21. Firebase is not recommended. Integrations that run on Firebase might be rejected.

3. Metadata (name, descriptions, permissions, and so on)

3.1. For corporate customers, developer accounts need to be created using a generic or shared corporate email address, and a company employee's name. This is to ensure that the Nest Developer Terms of Service have been agreed to by a real person with authority to bind the corporate entity, but yet allow flexibility of access to the developer account. For individual developers this may not be possible and a personal email may be used.

4.3. Products that include the ability to log out or disconnect from Nest must use the deauthorization API to notify Nest of disconnect.
4.4. Products should use external browsers instead of embedding browsers within the product when requesting end-user authorization. Products that use embedded browsers (iframes) will be rejected.
4.5. Nest provides the ability for a user to remove a Works with Nest connection. Products that do not handle this revoked authorization by reverting to a disconnected state and removing all Nest user data will be rejected.
4.6. Products that do not handle permission upgrades and client versioning will be rejected.
4.7. Products may be deactivated for various operational reasons. When a product is inactive, it will become unusable. Products that do not provide support for an inactive client (for example, proper user error messaging) will be rejected.
4.8. Products that force users to reauthorize, after authorization has already been established, will be rejected.

5. Structures/Homes

Nest accounts provide users the ability to manage multiple homes and adjust their Away state. Products should support Nest accounts that may contain one or more homes. Some products may be linked to only one Nest home. In these cases, developers must provide users the ability to select the appropriate home. Once linked, developers must provide support for changes in homes, including addition and removal of homes, and updates to home data (for example home names). The following guidelines cover the requirements for handling Nest accounts that may have multiple homes.

5.1. Products that do not accommodate the possibility of multiple homes will be rejected.
5.2. Products that do not provide a user a way to select the appropriate home for linking (for example, a structure picker) will be rejected.

5.4. Products that cannot support multiple homes, each containing multiple devices of the same or different types, will be rejected.
5.6. Products that cannot support empty homes (structures), or a combination of empty and non-empty homes, will be rejected.

6.1. Products that instruct the user to turn off sensors and learning features of the Nest Learning Thermostat will be rejected.
6.2. Products that trigger thermostat updates without user interaction (for example, triggers and rules), and do not provide an indicator of any action that failed, will be rejected.
6.3. Products that do not maintain temperatures, setpoints and ambient, in sync with the actual device temperatures, within seconds, may be rejected.
6.4. Products that do not handle multiple thermostats in one or multiple structures may be rejected.
6.5. Products that do not update when thermostat data updates will be rejected.
6.6. Products that do not support all possible thermostat modes, for example Heat, Cool, Heat-Cool, Off, Eco, may be rejected.

7.5. Products that do not update Nest Protect names or locations, within seconds of updates, may be rejected.

8. Nest Cam + Dropcam

This document represents our best effort to share how we review Works with Nest products submitted for approval. We hope it serves as a helpful guide as you develop and submit your apps and integrated interfaces. This is a living document that will be updated as we are presented with new apps, implementations, and situations.

As a developer of products for the Works with Nest program, you are bound by the following guides:

Nest's approval of your product does not waive any Nest rights under these agreements. These guidelines are intended to assist you in gaining acceptance for your product through the Works with Nest Product Review process, and not to amend or remove provisions from any other agreement.

Nest reserves the right to interpret and apply these guidelines at Nest's sole discretion, and to change the interpretation or application of these guidelines at any time, including during the Product Review process.
