# Inviting Users via Third-Party Integrations
> Invite users to Rootly directly from supported integrations such as Slack, Microsoft Teams, Opsgenie, PagerDuty, and Splunk On-Call to onboard quickly.
You can invite users directly from supported third-party integrations to quickly onboard your team without manually entering email addresses.
Rootly currently supports inviting users from:
* **Slack**
* **Opsgenie**
* **PagerDuty**
* **Splunk On-Call (formerly VictorOps)**
The integration must be configured before users can be imported or invited.
## Invite Users from an Integration
In the top-left corner, click the drop-down next to your organization name and select **Organization Settings**.
Select **[Members](https://rootly.com/account/memberships)**, then choose **Invite from \[Integration]**.
Depending on the integrations configured for your organization, you may see:
* **Invite from Slack**
* **Invite from Opsgenie**
* **Invite from PagerDuty**
* **Invite from Splunk On-Call**
Rootly loads a list of users from the selected integration.
Use the search field to filter users by name or email (or username for Opsgenie).
Select the users you want to invite and click **Invite**.
Invitation emails are sent automatically to the selected users.
## Role Assignment
Users invited through third-party integrations are assigned roles the same way as standard invitations.
You can assign:
* **Incident Response roles** for incident management permissions
* **On-Call roles** for schedules, alerting, and escalation workflows
If roles are not selected during invitation, Rootly applies your team’s **default roles**.
Configure default roles in **Organization Settings** to standardize permissions for new users.
## Integration Behavior
### Slack
Slack invitations may be limited by your configured **email domain restrictions**.
If your organization restricts invitations by email domain, only Slack users with matching email addresses will appear in the list.
### PagerDuty, Opsgenie, and Splunk On-Call
Users are pulled from the connected integration account. If expected users do not appear, verify the integration connection and permissions.
## Browsing and Searching Users
The integration user list supports:
* **Search** to filter users by name, email, or username
* **Pagination** for navigating large user lists
* **Sorting** by user name
This helps you quickly locate users in large organizations.
## User Acceptance and Sign-Up
After an invitation is sent, the user receives an email with a link to join your Rootly organization.
Accepting the invite takes them to the sign-up page:
Users can sign in using:
* **Google**
* **Slack**
* **SSO**
* **Email and password**
Passwords must include:
* At least **10 characters**
* One **lowercase letter**
* One **uppercase letter**
* One **number**
* One **special character**
After completing sign-up, the user is added to your organization with the assigned roles.
## Best Practices
* Confirm integrations are configured before inviting users
* Review your default role configuration before onboarding users
* Use integration-based invitations to onboard large teams faster
* Use search to locate specific users in large integration lists
## Troubleshooting
Ensure the integration is configured and connected in **Organization Settings → Integrations**.
Verify the integration connection and permissions. If the integration cannot access user data, the list may appear empty.
Slack user visibility may depend on your configured email domains. Only users with matching domains may appear.
Invitations may fail if the email address is invalid, the user is already a member, or a duplicate invitation already exists.
Role assignment depends on your organization permissions and configuration. If roles are not set, default roles will be applied automatically.
