Getting Started with the Fitbit APIs

Creating a Fitbit Developer Account

To use the Fitbit APIs, you need to have a Fitbit developer account. To create a developer account,

  1. Go to to register for a account. The email address must be valid to complete the verification process. An existing account can be used.
  2. A verification email will be sent to the user requesting a response.
    Once the email address is verified, the user will be able to access to register new applications used to query the Web APIs.

To change the registered email address of the Fitbit developer account, please contact Fitbit Web API support for assistance.

TIP: For larger organizations, we recommend the developer account email address be a distribution list. Distribution lists are easier to manage ownership as people migrate throughout the company.

Registering an Application

An application must be registered within the developer account prior to calling the Fitbit Web APIs for the first time. Each registered application is provided with a client ID and secret. These client credentials will need to be referenced by the application during user authorization.

Access Types

Applications operate in a read-only or read & write manner. This is an application-level setting and applies to all scopes. This is configured in the application settings at

Only configure "Read & Write" access if you're sending data to Fitbit.

All registered applications will appear under the developer’s account at Selecting one of the applications will display a summary of the application settings (see image).

NOTE: Never put your client secret in distributed code, such as apps downloaded through an app store or client-side JavaScript. Also, never give your client secrets to external people or post it on a public forum. Fitbit employees may ask for this information to troubleshoot problems. The information should be sent privately, and only the first 10 characters of your client secret will typically be requested to verify application ownership.
