System APIs

Overview

This page contains the APIs that are used for retrieving and updating the system configuration.

Documentation for this API has been updated for version 1.30 and above. For previous versions, you can view the Pre 1.30 System documentation if needed.

Retrieve the System Configuration

This API is used to retrieve the System Configuration.

Request

Retrieve the System Configuration

URI

GET /api/system-configuration

Response

The response for this API contains the System Configuration.

Table 1. Response Codes
Code	Description
200	The request was successful. The response will contain a JSON body.
401	You did not supply a valid Authorization header. The header was omitted or your API key was not valid. The response will be empty. See Authentication.
500	There was an internal error. A stack trace is provided and logged in the FusionAuth log files. The response will be empty.
503	The search index is not available or encountered an exception so the request cannot be completed. The response will contain a JSON body.

Response Body

systemConfiguration.auditLogConfiguration.delete.enabled [Boolean]

Whether or not FusionAuth should delete the Audit Log based upon this configuration. When true the auditLogConfiguration.delete.numberOfDaysToRetain will be used to identify audit logs that are eligible for deletion. When this value is set to false audit logs will be preserved forever.

systemConfiguration.auditLogConfiguration.delete.numberOfDaysToRetain [Integer]

The number of days to retain the Audit Log.

systemConfiguration.corsConfiguration.allowCredentials [Boolean]

The Access-Control-Allow-Credentials response header values as described by MDN Access-Control-Allow-Credentials.

systemConfiguration.corsConfiguration.allowedHeaders [Array<String>]

The Access-Control-Allow-Headers response header values as described by MDN Access-Control-Allow-Headers.

systemConfiguration.corsConfiguration.allowedMethods [Array<String>]

The Access-Control-Allow-Methods response header values as described by MDN Access-Control-Allow-Methods. The possible values are:

GET
POST
PUT
DELETE
HEAD
OPTIONS

systemConfiguration.corsConfiguration.allowedOrigins [Array<String>]

The Access-Control-Allow-Origin response header values as described by MDN Access-Control-Allow-Origin. If the wildcard * is specified, no additional domains may be specified.

systemConfiguration.corsConfiguration.debug [Boolean]

Whether or not FusionAuth will log debug messages to the event log. This is primarily useful for identifying why the FusionAuth CORS filter is rejecting a request and returning an HTTP response status code of 403.

systemConfiguration.corsConfiguration.enabled [Boolean]

Whether the FusionAuth CORS filter will process requests made to FusionAuth.

systemConfiguration.corsConfiguration.exposedHeaders [Array<String>]

The Access-Control-Expose-Headers response header values as described by MDN Access-Control-Expose-Headers.

systemConfiguration.data [Object]

An object that can hold any information about the System that should be persisted.

systemConfiguration.eventLogConfiguration.numberToRetain [Integer]

The number of events to retain. Once the the number of event logs exceeds this configured value they will be deleted starting with the oldest event logs.

systemConfiguration.loginRecordConfiguration.delete.enabled [Boolean]

Whether or not FusionAuth should delete the login records based upon this configuration. When true the loginRecordConfiguration.delete.numberOfDaysToRetain will be used to identify login records that are eligible for deletion. When this value is set to false login records will be preserved forever.

systemConfiguration.loginRecordConfiguration.delete.numberOfDaysToRetain [Integer]

The number of days to retain login records.

systemConfiguration.reportTimezone [String]

The time zone used to adjust the stored UTC time when generating reports. Since reports are usually rolled up hourly, this timezone will be used for demarcating the hours.

Update the System Configuration

This API is used to update an existing System Configuration.

No Id is required to update this object.

You must specify all of the properties of the System Configuration when calling this API with the PUT HTTP method. When used with PUT, this API doesn’t merge the existing System Configuration and your new data. It replaces the existing System Configuration with your new data.

Utilize the PATCH HTTP method to send specific changes to merge into an existing System Configuration.

Request

Update the System Configuration

URI

PUT /api/system-configuration

PATCH /api/system-configuration

Available since 1.12.0

When using the PATCH method, use the same request body documentation that is provided for the PUT request. The PATCH method will merge the provided request parameters into the existing object, this means all parameters are optional when using the PATCH method and you only provide the values you want changed. A null value can be used to remove a value. Patching an Array will result in all values from the new list being appended to the existing list, this is a known limitation to the current implementation of PATCH.

Rebuild the Elasticsearch index

This API is used to rebuild the Elasticsearch index. In general you do not need to rebuild the search index at runtime, and doing will cause additional CPU and I/O overhead to FusionAuth until the request has completed. Please be careful with this API.

This API may be useful if you are building a new FusionAuth environment from an existing database w/out moving over an existing search index. In this scenario you will need to rebuild the search index from the database in order see the Users show up in the UI or use any of the Search APIs.

Request Body

index [String] Required

The name of the index to rebuild. The possible values are:

Retrieve System Status

The Status API is used to retrieve the current status and metrics for FusionAuth. This is useful for health checks and monitoring.

FusionAuth also supports a system status check using Prometheus.

Request

Return the system status without an API key

URI

GET /api/status

Return the system status with an API key

URI

GET /api/status

Response

The JSON response from the Status API is complex and subject to change. The only exception is the version key.

version will not change and will be returned as below. As a reminder, an API key is required to obtain this value.

{
//..
    "version": "1.26.1"
//..
}

The specific contents of the JSON body are not documented here. If you choose to use this API for monitoring purposes you should primarily use the response code to indicate server health. If you receive a 200 you may consider FusionAuth in a healthy state. The response body is intended for use by FusionAuth support.

Table 8. Response Codes
Code	Description
200	The FusionAuth is functioning properly
452	The FusionAuth is failing to make a JDBC connection to the configured database.
453	The FusionAuth database connection pool connectivity is below the healthy threshold. Additional information may be available in the JSON response which is retrieved when using an API key.
454	The FusionAuth database connectivity pool connectivity is below the healthy threshold. Additional information may be available in the JSON response which is retrieved when using an API key.
460	FusionAuth is using Elasticsearch and the search service is reporting an unhealthy cluster status. In a cluster with 2+ nodes, this means the cluster status is being reported as `yellow` or `red`. In a single-node Elasticsearch configuration this means the cluster status is `red.`
500	The FusionAuth server is not functioning properly. This could indicate that the database connectivity failed or one or more services within FusionAuth failed. Consult the FusionAuth Troubleshooting to learn more about the failure or contact FusionAuth support for assistance.

Retrieve System Version

The Version API is used to retrieve the current version of FusionAuth.

Request

Return the FusionAuth system version with an API key
