# Prerequisites

To ensure the Request app functions, there are some setup requirements that must be completed in the Govern app.

## Required for all use cases

1. [Register users in Immuta](/saas/configuration/people/index.md) to ensure users can log in to the Request app, request access, and be provisioned access in the data platform.
   1. If the configured [identity manager](/saas/configuration/people/section-contents/reference-guides/index.md) (IAM) to Immuta is syncing attributes (groups don't matter) from it, the checkbox to allow Immuta attributes to be applied to the IAM's users and groups **must** be enabled. To enable this setting, [edit the IAM from the Govern app settings page](/saas/configuration/application-configuration/how-to-guides/config-builder-guide.md#use-existing-identity-access-manager).
2. [Register a connection](/saas/configuration/integrations/data-and-integrations.md#registering-a-connection) to create data sources and assets with request links. These data sources can then be added to data products.

## Required to use Immuta as a marketplace

If you want to publish data products in Immuta for your users to browse, you must set up the following:

1. [Assign data sources to domains](/saas/configuration/domains/configure-domains.md#assign-data-sources-to-a-domain). Each data product is comprised of data sources from a single domain, [allowing you to segment your organization's data](/saas/configuration/domains/domains.md) and delegate permissions to specific users that are knowledgeable about the data.
2. Grant users permission to be [data product managers](/saas/request/introduction/user-types.md#data-product-managers), allowing them to publish data from the domain they are privileged in.

## Required for masking exception requests

If you want users to have the option to request for a masked column to appear unmasked, you must set up the following:

* Author masking [data policies](/saas/govern/secure-your-data/authoring-policies-in-secure/data-policies.md). Masking data policies mask data; then users can make masking exception requests to gain access to the unmasked data.

## Optional Govern app setup

The following features can be set up to improve workflows, better user experience, or align with organizational governance goals:

* View reports and monitor Immuta and user query activity.
* [Identify](/saas/configuration/tags/data-discovery.md) and tag data automatically.
* [Customize the branding](/saas/request/configure/how-to-guides/customize-the-marketplace-branding.md) of the Request app.
