IraK.15468 (Customer) asked a question.
User provisioning does not work with my application integration. Creating or updating a user in OKTA doesn`t reflect in my application. I created a user and checked the OKTA System Log, where I see that the application.provision.user.push action was successful, but application.provision.user.sync failed. Therefore, assigning a user to an application fails with the message "Automatic provisioning of user to app failed: Matching user not found." However, if I create a user manually in my application using the same email I used in OKTA for a specific user, assignment to the application is successful. I have verified the configuration for my app, and "Enable API integration" is checked. I tested the API credentials, and the connection is successful. Provisioning to the app is set up, and the Create Users, Update User Attributes, and Deactivate Users features are also enabled. Attribute mappings are defined.
Could you please help me identify such

Hi @IraK.15468 (Customer) , Thank you for reaching out to the Okta Community!
Is this a Custom SCIM app or one of the apps from the Okta Integration Network (OIN)?
If OIN, which app?
Regards.

@IraK.15468 (Customer) Typically this happens when the Create option under provisioning - To App is not enabled.
Okta is trying to check and link user instead of trying to create.
Could you check if 'Create' option is checked under provisioning - To App
depends on the app you are writing to. unfortunately theres not consistency between apps. it could be a permissions issue with the API account youre using to create users
Try importing from the app in Okta (Import - Import Now). That should bring in your users and hopefully, match them to the users assigned in Okta. Once they are matched, try initiating the change in Okta again and see if that works.
