IP Authorization Overview


IP Authorization gives an Administrator control over who can access an Org by validating a user's IP address with IP addresses on the Org's IP Allow List. Use the API (Swagger) to configure the IP Authorization function with one of the following options:

  • Off:  Disables the IP Authorization control. User login attempts using SSO (Single Sign On), or username and password will not use the IP Authentication process.
  • On: Enables the IP Authorization control. User login attempts using SSO, or username and password will use the IP Authentication process.

Enabling the IP Authorization control does not enable the Resolver API IP token validation function.

  • bypass_sso:  Enables the IP Authorization control for user login attempts using a username and password and bypasses SSO login attempts.

Users are not able to configure the IP Authorization control without assistance from the Resolver Support team. Please contact Resolver Support for assistance enabling or disabling the IP Authorization control.

ipAllowList Endpoint

The ipAllowList endpoint in Core API in Swagger allows you to configure/manage the IP Allow List.  Administrators can add, update, or delete entries using the following calls:

  • GET /user/ipAllowList: This call will retrieve a list of all IP address on an Org's IP Allow List.
  • POST /user/ipAllowList: This call allows an Administrator to add an IP address to an Org's IP Allow List
  • DELETE /user/ipAllowList/{id}: This call will delete an IP address from an Org's IP Allow List
  • PUT /user/ipAllowList/{id}: This call will edit/update an IP address on an Org's IP Allow List.
