SCIM Group Request Converter Lambda

SCIM Group Request Converter Lambda

If you would like to convert an incoming SCIM Group request into a Group, you must specify a lambda in the SCIM configuration. This lambda will be invoked prior to the Group being acted upon.

When you create a new lambda using the FusionAuth UI we will provide you an empty function for you to implement. If you are using the API to create the lambda you will need to ensure your function has the following signature:

function convert(group, members, options, scimGroup) {
  // Lambda code goes here
}

This lambda must contain a function named convert that takes four parameters. The parameters that the lambda is passed are:

• group - the FusionAuth Group object

• members - the members in this FusionAuth Group

  • members[x].userId - The Id of the FusionAuth User

  • members[x].data.$ref - The URI to retrieve the SCIM User representation of the FusionAuth User

    • ex. https://login.piedpiper.com/api/scim/v2/Users/902c246b-6245-4190-8e05-00816be7344a

• options - options contains optional FusionAuth request options

  • options.roleIds

• scimGroup - the SCIM request object

The FusionAuth object is well documented here in the Group API documentation. The SCIM Group object is a JavaScript object containing the SCIM Group request JSON payload. See SCIM Group.

You may add or modify anything in the group, members and options objects.

Assigning the Lambda

Once a lambda is created, you must assign it to a Tenant. See the SCIM tab in the Tenant configuration.

Default Lambda

A default SCIM Group Request Converter Lambda that converts an incoming SCIM Group request to a FusionAuth Group is available and may be used or modified. The lambda function is documented below.

function convert(group, members, options, scimGroup) {

  // Un-comment this line to see the scimGroup object printed to the event log
  // console.info(JSON.stringify(scimGroup, null, 2));

  // Request options
  // FusionAuth allows you to assign one or more application roles to a group.
  // To use this feature, assign one or more application Ids here.
  // options.roleIds = [];

  // Set the name of the group using the SCIM Group displayName
  group.name = scimGroup.displayName;

  // Build a members array with a userId and a $ref in custom data
  if (scimGroup.members) {
    for (var i = 0; i < scimGroup.members.length; i++) {
      members.push({
        userId: scimGroup.members[i].value,
        data: {
          $ref: scimGroup.members[i]['$ref']
        }
      });
    }
  }
}
