Fides Configuration
Configuration Variables


Setting Configuration Values

Fides can be configured in two different ways: either via a toml file or via environment variables. Both methods can be used simultaneously, with environment variables taking precedence over the toml file values.

Using a Configuration File

Fides will use the first config file it can read from the following locations. Listed in order of precedence they are:

  1. At the path specified using the config file argument passed through the CLI, i.e. fides -f <config_path>
  2. At the path specified by the FIDES__CONFIG_PATH environment variable
  3. In the current working directory it will check for a subdir .fides and a file within named fides.toml, i.e. ./.fides/fides.toml

Generating a Config File

If you'd like to generate a new config file automatically using default values, run fides init. This will create the file at the default location of ./.fides/fides.toml

Setting Values Via Environment Variables

Fides follows a set pattern for configuration via environment variables. It looks for environment variables that start with FIDES followed by the config subsection name, followed by the key name, all separated with double underscores. In practice this would look like FIDES__<SUBSECTION>__<KEY>

As a toml configuration value:

host = config_example

As an environment variable:


Viewing your configuration

You can view the current configuration of your application via either the CLI or API.


To view your application configuration via the CLI, run:

fides view config

This will show all configuration variables, including sensitive ones. It is printed to the console as valid toml, so this can be copy/pasted as needed.


To view your application configuration in the API, run:

GET /api/v1/config

For security reasons, sensitive configuration values will not be shown here.

identity_verification_attempt_limitint3The number of identity verification attempts to allow.
envstr, dev or proddevThis determines which API endpoints require authentication. The default, dev, does not apply authentication to endpoints typically used by the CLI. The other option, prod, requires authentication for all endpoints that may contain sensitive information.


Environment variable prefix: FIDES__EXECUTION__

privacy_request_delay_timeoutint3600The amount of time to wait for actions which delay privacy requests (e.g., pre- and post-processing webhooks).
task_retry_countint0The number of times a failed request will be retried.
task_retry_delayint1The delays between retries in seconds.
task_retry_backoffint1The backoff factor for retries, to space out repeated retries.
subject_identity_verification_requiredboolFalseWhether privacy requests require user identity verification.
require_manual_request_approvalboolFalseWhether privacy requests require explicit approval to execute.
masking_strictboolTrueIf set to True, only use UPDATE requests to mask data. If False, Fides will use any defined DELETE or GDPR DELETE endpoints to remove PII, which may extend beyond the specific data categories that configured in your execution policy.


Environment variable prefix: FIDES__USER__

encryption_keyStringtest_encryption_keyAn arbitrary string used to encrypt the user data stored in the database. Encryption is implemented using PGP.
analytics_opt_outBoolean""When set to true, prevents sending anonymous analytics data to Ethyca.


Environment variable prefix: FIDES__CREDENTIALS__

The credentials section uses custom keys which can be referenced in specific commands that take the --credentials-id option. For example, a command that uses a credential might look like fides scan dataset db --credentials-id app_postgres. The credential object itself will be validated at the time of use depending on what type of credential is required. For instance if fides scan system okta is used, it will expect the object to contain orgUrl and token key/value pairs. In the case of a typical database like postgres, it will only expect a connection_string. The following is an example of what a credentials section might look like in a given deployment with various applications:

my_postgres.connection_stringStringSets the connection_string for my_postgres database credentials.
my_aws.aws_access_key_idStringSets the aws_access_key_id for my_aws credentials.
my_aws.aws_secret_access_keyStringSets the aws_secret_access_key for my_aws credentials.
my_aws.region_nameStringSets the region_name for my_aws credentials.
my_okta.orgUrlStringSets the orgUrl for my_okta credentials.
my_okta.tokenStringSets the token for my_okta credentials.

Admin UI

Environment variable prefix: FIDES__ADMIN_UI__

enabledboolTrueToggle whether the Admin UI is served from /.


Environment variable prefix: FIDES__NOTIFICATIONS__

send_request_completion_notificationboolFalseWhen set to True, enables subject notifications upon privacy request completion.
send_request_receipt_notificationboolFalseWhen set to True, enables subject notifications upon privacy request receipt.
send_request_review_notificationboolFalseWhen set to True, enables subject notifications upon privacy request review.
notification_service_typeStringN/ASets the notification service type used to send notifications. Accepts mailgun, twilio_text, or twilio_email.

Additional environment variables

The following environment variables are not included in the default fides.toml configuration, but may be set in your environment:

ENV VariableDefaultDescription
FIDES__HOT_RELOADFalseIf True, the Fides server will reload code changes without needing to restart the server. This variable should always be set to False in production systems.
FIDES__DEV_MODEFalseIf True, the Fides server will log error tracebacks, and log details of third party requests. This variable should always be set to False in production systems.
FIDES__CONFIG_PATHNoneIf this is set to a path, that path will be used to load .toml files first. Any .toml files on this path will override any installed .toml files.

Celery Configuration

Fides uses Celery (opens in a new tab) for asynchronous task management.

To simplify deployments and remove the need for two different toml configuration files, it is possible to configure celery via the Fides configuration file. Any valid configuration key/value pair for celery can instead be added to the Fides toml configuration file and will automatically be passed through to the celery deployment. Note that Fides will not validate any of these key/value pairs. See the above configuration file reference for an example of using celery configuration pass-through.

For a full list of possible variable overrides, see the Celery configuration (opens in a new tab) documentation.
