# [Organization] - Invite Users to Organization

This page explains how to invite users to your Contentstack Organization (including SSO-enabled Organizations), who should perform these steps (Org Admins), and when to use them (when onboarding new users or managing Organization access).

## Invite Users to Organization

When you add users to your Organization, you send them an invitation mail with the required details to join your stack.

Log in to your [Contentstack account](https://www.contentstack.com/login) and perform the steps given below to invite a [user](/docs/developers/organization/organization-users#invite-new-user-to-your-organization):
- Click the Organization dropdown in the header and select the Organization that you want to access.
- Click the “Org Admin” icon on the left navigation panel and select **Users** from the menu. You will see the list of users within your Organization.
- Click the **Invite User** button.
- In the **Invite User** page, enter the following details for the new user:**Email**: Enter the user’s email address
- **Assign Organization Role**: Assign an [Organization role](/docs/owners-and-admins/organization-roles) to the new user. You can only assign either the [Admin](/docs/owners-and-admins/organization-roles#organization-admin) or [Member](/docs/owners-and-admins/organization-roles#organization-member) role.
- **Stack-level permissions**: Assign stack-specific roles to the user.
- Finally, click **Invite** to invite the user.

**Note**: If users are directly invited to an Organization but not assigned any stacks, they won’t be a part of any stack and thus will not be able to do anything..

## Invite Users to SSO-enabled Organizations

For [Single Sign-On (SSO](https://www.contentstack.com/docs/developers/single-sign-on/about-single-sign-on-sso/)) enabled organizations, the process of inviting users works similarly. The only difference is that if “[Strict Mode](/docs/developers/single-sign-on/set-up-sso-in-contentstack#user-management-in-contentstack)” is disabled for your SSO organization, you may get an additional checkbox **Allow Access without SSO** on this screen. Checking this box ensures that the invited user can access the SSO-enabled organization using his/her Contentstack credentials, instead of IdP credentials.

## API Reference

You can refer to the following user-related API requests:
- [Add users to Organization](/docs/developers/apis/content-management-api#add-users-to-organization)
- [Resend pending Organization invitation](/docs/developers/apis/content-management-api#resend-pending-organization-invitation)
- [Get all Organization invitations](/docs/developers/apis/content-management-api#get-all-organization-invitations)

## Common questions

**How do I invite a user to my Organization?**  
Log in to your Contentstack account, go to **Org Admin** → **Users**, click **Invite User**, fill in the required details, and click **Invite**.

**What happens if I invite a user but don’t assign any stacks?**  
**Note**: If users are directly invited to an Organization but not assigned any stacks, they won’t be a part of any stack and thus will not be able to do anything..

**What is different when inviting users to an SSO-enabled Organization?**  
If “Strict Mode” is disabled, you may see an additional checkbox **Allow Access without SSO**, which allows the invited user to access the SSO-enabled organization using Contentstack credentials instead of IdP credentials.

**Where can I find API endpoints related to Organization invitations?**  
See the **API Reference** section for links to user-related API requests, including adding users, resending invitations, and listing invitations.
