Values & Secrets
Introduction
Atlas App Services Values and App Services Secrets are static, server-side constants that you can access or link to from other components of your application. You can access Values directly from Atlas Functions and rule expressions and link Secrets to configuration values for authentication providers.
Concepts
Value
A value is a named reference to a piece of static data stored by App Services that you can access in functions and rule expression. Values provide an alternative to hardcoding configuration constants directly into your functions and rules. In other words, values allow you to separate deployment-specific configuration data from the business logic of your app.
Values can resolve to two types of data:
A plain text Value resolves to a regular JSON object, array, or string that you define.
A secret Value resolves to the value of a Secret.
Secret
A Secret is a private value that is stored on the App Services backend, hidden from users, and not included in exported applications. Secrets are useful for storing sensitive information such as an API key or an internal identifier.
You cannot directly read the value of a Secret after defining it. Instead, you link to the Secret by name in authentication provider and service configurations. If you need to access the Secret from a Function or Rule, you can link the Secret to a Value.
A Secret value has a maximum character length of 500 characters.
Environment Values
An environment value is similar to a regular text Value but can dynamically resolve to one of multiple values depending on an application-wide environment tag. You can specify different values for each of the following supported environment tags:
"""development""testing""qa""production"
You can access defined environment values in functions with
context.environment.values and in
rule expressions with %%environment.

Summary
App Services Values and App Services Secrets are server-side constants you can use in your app.
App Services Values allow you to separate deployment-specific configuration data from the business logic of your app.
App Services Secrets store sensitive data. You cannot export or directly read a Secret. Instead, you access a Secret indirectly via a named App Services Value.
