Form Fields

This feature is only available in paid plans. Please visit our pricing page to learn more.

Overview

A FusionAuth Form Field is an object that can be customized to receive input within a FusionAuth Form.

The following APIs are provided to manage Forms Fields.

Create a Form Field

This API is used to create a new Form Field.

Request

Create a Form Field with a randomly generated Id

POST /api/form/field

Create a Form Field with the provided unique Id

POST /api/form/field/{fieldId}

Request Parameters

fieldIdUUIDDefaults to secure random UUID

The Id to use for the new Form Field. If not specified a secure random UUID will be generated.

Request Body

field.confirmBooleanDefaults to false

Determines if the user input should be confirmed by requiring the value to be entered twice. If true, a confirmation field is included.

field.consentIdUUID

The Id of an existing Consent. This field will be required when the type is set to consent.

Using a form field for consent allows you to leverage a FusionAuth consent to allow your end users to self consent to terms and service, end user license agreements, or other opt-in, or opt-out agreements during registration.

field.controlStringDefaults to text

The Form Field control. The possible values are:

checkbox
number
password
radio
select
textarea
text

The field control can only be set for custom fields, and if not provided the default value will be text. For all managed fields, such as user.firstName, the control will be set by FusionAuth and it may not be modified.

field.dataObject

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

This may be useful to add additional meta data to the field that will help you style or render the Form Field. For example, in the JSON example an attribute is added to this data field as follows:

{
  "data": {
    "leftAddOn": "user"
  }
}

This additional meta data is then used to render an icon on the Form Field. Use of this additional data is optional and not required to render the field.

field.descriptionString

A description of the Form Field.

field.keyStringrequired

The key is the path to the value in the user or registration object.

Predefined keys

Predefined keys are typed values managed by FusionAuth. When using a pre-defined key, the field data type and form control are not configurable.

registration.preferredLanguages Available since 1.20.0
registration.roles Available since 1.20.0
registration.timezone Available since 1.20.0
registration.username
user.birthDate
user.email
user.firstname
user.fullName
user.imageUrl Available since 1.20.0
user.lastName
user.middleName
user.mobilePhone
user.password
user.preferredLanguages Available since 1.20.0
user.timezone Available since 1.20.0
user.username

Custom Keys

When defining a key to store custom data, you may use one of the following prefixes:

user.data.
registration.data.

For example, in order to store a custom value on the user object to collect the User’s favorite color, set the key value equal to user.data.favoriteColor.

A valid key name must not contain spaces or special characters. An array may be specified by using the array syntax of [0] to indicate the first position in an array. Nested objects may be specified by using the object syntax of ['foo'] to indicate the named property of the object named foo. Consider the following examples:

user.data.preferences[0] would store the value in the first position of an array named preferences.
user.data.preferences['color'] would store the value in an object named preferences with a key of color.

Localization

You may localize the displayed value of this key during registration by adding the key to your theme. For example, if you specify the key value of user.data.favoriteColor this key value be rendered in the UI.

If you were to add the following messages to your theme, the localized form of the value will be shown to the end user. This allows you to provide a human readable field name and optionally localize the field name as well.

user.data.favoriteColor=Favorite color

field.nameStringrequired

The unique name of the Form Field.

field.optionsArray<String>

A list of options that are applied to checkbox, radio, or select controls.

The options for a field must conform to the field.type . If the field.type is number, the options must be numbers. If the field.type is boolean, only true and/or false are allowed.

You may localize the displayed values during registration by adding these values to your theme.

For example, if you specify the values ["red", "green", "blue"] as the field options, these will be stored on the user in this lowercase form. By default the values red, green and blue will be rendered in the UI.

If you were to add the following messages to your theme, the capitalized form of the values will be shown to the end user. This allows you to provide a human-readable form of the value and optionally localize the displayed values.

Default

red=Red
green=Green
blue=Blue

Spanish

red=Roja
green=Verde
blue=Azul

field.requiredBooleanDefaults to false

Determines if a value is required to complete the form.

field.typeStringDefaults to string

The data type used to store the value in FusionAuth. The possible values are:

bool the value must be a boolean value, true or false
consent the value will be used to complete self consent
date the value will be stored as a date. The value must be formatted as ISO-8601 or YYY-MM-DD, you may want to use a JavaScript data picker that can convert the selected value to this format.
email the value will be expected to be a valid email address
number the value will be stored as a numerical value
string the value will be stored as a string

All user provided input will be validated to ensure it can be stored in this data type. If the user input cannot be converted a validation error will be shown to the user. When providing options for this control each option must also be compatible with this data type. When using the `consent` type, the field consentId is required and must be included in the request. The data type can only be set for custom fields, and if not provided the default value will be `string`. For all managed fields, such as `user.firstName`, the data type will be set by FusionAuth and it may not be modified.

field.validator.enabledBooleanDefaults to false

Determines if user input should be validated.

field.validator.expressionString

A regular expression used to validate user input. Must be a valid regular expression pattern.

See Pattern for examples and syntax.

Update a Form Field

This API is used to update an existing Form Field.

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

Utilize the PATCH HTTP method to send specific changes to merge into an existing Form Field.

Some attributes, such as type , cannot be changed after form field creation.

Request

Update the Form Field with the given Id

PUT /api/form/field/{fieldId}

PATCH /api/form/field/{fieldId}

When using the PATCH method, you can either use the same request body documentation that is provided for the PUT request for backward compatibility. Or you may use either JSON Patch/RFC 6902] or JSON Merge Patch/RFC 7396. See the PATCH documentation for more information.

When using the PATCH method with a Content-Type of application/json the provided request parameters will be merged 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.

Request Parameters

fieldIdUUIDrequired

The Id of the Form Field to update.

Request Body

field.confirmBooleanDefaults to false

Determines if the user input should be confirmed by requiring the value to be entered twice. If true, a confirmation field is included.

field.consentIdUUID
