Single Sign-On (SSO) Integration

Integrate your company’s SSO with the Coupa Supplier Portal for simplified login and access management. To set this up, you’ll need to be an account Admin.

Suppliers subscribed to Coupa Advanced can configure Single Sign-On (SSO) in Coupa to integrate their company’s SSO with the Coupa Supplier Portal (CSP) for secure, streamlined logins, and access management.

To set this up, you’ll need to be an account Admin.

How to set up the SSO integration

    Follow these steps:

    1.  Download your identity provider’s SAML metadata file.
    2. Log in as a CSP Admin.
    3. Navigate to Admin > Single Sign-On Setup.
    4. Upload the metadata file and click Save.
       While the metadata file upload is taking place, please wait for it to be completed.
    5. Once the connection is confirmed, all users will log in via your SSO provider - no separate CSP password required.
    Note

    During the upload process, you’ll see a green check mark next to the metadata file name with the Entity ID and Primary Certificate information displayed.
    When the process is complete, the
    SSO page refreshes with a green banner confirming that your SSO provider is successfully connected. An Active status will show next to the certificate expiration date.

    Once connected, your users access their CSP account through the SSO provider. When they sign in to the CSP from the Login page, they provide their email address and then continue the login process through the SSO provider. A separate password for the CSP is no longer required.

    Update or remove SSO

    As a CSP Admin user, you can update, disable or remove your SSO integration.

    • To update: Remove the existing provider and upload a new SAML file
    • To disable temporarily: Use the Disable button in the SSO Setup Page
    • To remove permanently: Use the Remove button in the SSO Setup Page
    Important

     If your SSO certificate expires, all users lose access to the CSP.  Admin(s) will receive a reminder in their email before the expiration date: before the certificate expires, remove your SSO provider and reupload your SAML file. Contact supplier@coupa.com for assistance in restoring access.

    If SSO is disabled, the user(s) of your CSP account need to reset their passwords. When they go to the CSP Login page, they need to provide their email address and a new password to access the account.
