Setting up OCI Notification Service - 404 error

KDROct 8 2025 — edited Oct 8 2025

Hello - I am wondering if anyone has successfully setup the OCI Notification Service for use with an OIC Integration? I am looking to generate an SMS text message from an integration utilizing the OCI Notification Service. I believe I have done all the necessary setups in both OCI console and OIC, however I am getting 404 errors (NotAuthorizedOrNotFound) when I try to make the REST call from either OIC or from the command-line utility (oci-cli).

I've reviewed the setup on the OCI console, this is what I've done:

  1. Created Topic and SMS Subscription, then confirmed the SMS subscription in the root compartment:

  2. Created Dynamic Group in the OracleIdentityCloudService domain in root compartment and assigned matching rule with OCID from OIC test instance (tested with both Dynamic groups and user groups below in the policy thinking that this was the issue):

  1. Created new Policy in root compartment with the following Policy Statements (tried several combinations of dynamic groups, user groups, and compartment / tenancy)

  1. Ensured that service account user (making the REST call) is a member of the group ‘PB3-Integration-Users’:

  2. Generated API keypair in Gitbash client and uploaded public key to user account in OCI:

  3. Create connection in OIC and upload Private key / fingerprint details:

  4. Run integration from both OIC and OCI-CLI client and same 404 "NotAuthorizedOrNotFound" error results:

Would appreciate any assistance with getting this working, thank you!
