Adds additional user attributes to the user pool schema¶

Description¶

Adds additional user attributes to the user pool schema. Custom attributes can be mutable or immutable and have a custom: or dev: prefix. For more information, see Custom attributes.

Amazon Cognito evaluates Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you must use IAM credentials to authorize requests, and you must grant yourself the corresponding IAM permission in a policy.

Usage¶

cognitoidentityprovider_add_custom_attributes(UserPoolId,
  CustomAttributes)

Arguments¶

• UserPoolId

  [required] The ID of the user pool where you want to add custom attributes.

• CustomAttributes

  [required] An array of custom attribute names and other properties. Sets the following characteristics:

  AttributeDataType

  The expected data type. Can be a string, a number, a date and time, or a boolean.

  Mutable

  If true, you can grant app clients write access to the attribute value. If false, the attribute value can only be set up on sign-up or administrator creation of users.

  Name

  The attribute name. For an attribute like custom:myAttribute, enter myAttribute for this field.

  Required

  When true, users who sign up or are created must set a value for the attribute.

  NumberAttributeConstraints

  The minimum and maximum length of accepted values for a Number-type attribute.

  StringAttributeConstraints

  The minimum and maximum length of accepted values for a String-type attribute.

  DeveloperOnlyAttribute

  This legacy option creates an attribute with a dev: prefix. You can only set the value of a developer-only attribute with administrative IAM credentials.

Value¶

An empty list.
