Environment Variables

Variables that are available across your entire workspace

What are environment variables?

Environment variables are persistent variables that are available across your entire workspace. Typically, these are used to store things like external API keys or other sensitive information that you need to use across multiple function stacks, without storing it in a database table.

Environment variables can be read in any logic or workflow, but they can not be modified from anywhere but this settings panel, so it’s best to only use them for things that you don’t need to change often.

Adding Environment Variables

Click the icon in the upper-right corner to open Settings.

On the next screen, click ‘Manage’ to edit your environment variables.

Click ’+ Add Variable’ at the bottom of the panel that opens to add a new variable.

Give your environment variable a name that you can easily recognize; this is how you’ll identify it when calling it in function stacks. Then, supply the value.

Using Environment Variables

Environment variables are available in any logic or workflow from a value dropdown under ENV.
