Built-in variables

Learn about the built-in variables you can use in your requests

Built-in variables are special variables whose value is automatically filled in by Bravo, in contrast to other user-defined variables.

To see the list of built-in variables, type "$" on the API collections text inputs:

Built-in variables

Name	Description	Use cases	Tutorial/example
${device.id}	A unique identifier that identifies the device of the user. (It changes if the user removes and installs the app, and is unique x app, following Privacy Guidelines from Apple).	Used to differentiate the data to allow customization per device i.e. a to-do list specific to the device can be done by using the device.id to filter the data.	See example
${device.lang}	Returns the language of the device, "es" for example	Used to help specify the language used i.e. you could filter a list of holiday destinations using the device.lang to get the same list in different languages
${device.platform}	Returns "ios" or "android"	Return the platform device or the user. Could be used in a web-view to display a different URL to each platform. i.e. QR code to download a mobile app in iOS or Android.	See video
${device.latitude}	Returns the user coordinates (latitude value)	Obtain the app user location and send it via API request. The user must have accepted location sharing first.	See tutorial
${device.longitude}	Returns the user coordinates (longitude value)	Obtain the app user location and send it via API request. The user must have accepted location sharing first.	See tutorial
${user.id}	Returns the user id from the normalized Bravo token if it's available	Once a user is logged in this can be used to customize the data, i.e. a todo list specific to the user by filtering the data specific for the user	See tutorial
${user.email}	Returns the user email from the normalized Bravo token if it's available	This will enable similar use cases to user.id but by having the user email available also allows integration with emailing tools. This will be personal information though so the user will need to ensure they have the email owner's permission to use it.	See tutorial
${user.access_token}	Returns the user access token from the authentication provider.	Once the user has logged in with the authentication provider, a unique access token will be generated. This token can be used to authenticate the requests sent from Bravo, targeting a custom backend. This token is more robust and secure than the ${user.id}.
