# Accessing variables in Mage

> You've got all of these great variables and secrets, now let's put them to use. Learn how to access them in your code. 🦸🏻‍♂️

Mage allows users to interpolate variables specific to your [pipeline](/getting-started/runtime-variable) or [project](/development/variables/environment-variables). The following syntax is specific to `yaml` and `SQL` files.

Here's a list of the different variables and functions you can use in your code:

| Syntax                              | Description                                                                           |
| ----------------------------------- | ------------------------------------------------------------------------------------- |
| `{{ env_var('secret') }}`           | Get secret from [environment variables](development/variables/environment-variables). |
| `{{ variables('secret') }}`         | Get secret from [runtime variables](getting-started/runtime-variable).                |
| `{{ mage_secret_var('secret') }}`   | Get secret from [Mage secrets](development/variables/secrets).                        |
| `{{ aws_secret_var('secret') }}`    | Get secret from [AWS Secrets Manager](production/deploying-to-cloud/secrets/AWS).     |
| `{{ azure_secret_var('secret') }}`  | Get secret from [Azure Key Vault](production/deploying-to-cloud/secrets/Azure).       |
| `{{ json_value(json_obj, 'key') }}` | Extract value from a JSON string.                                                     |
| `{{ n_days_ago(N) }}`               | Get the date `N` days ago (data integration pipelines only).                          |
