@Devishke de Silva Thank you for reaching out to us, As I understand you would like to know whether can we develop our own custom connector similar to the Workday/SuccessFactors connector to provision identities FROM our HR system INTO Entra ID?
At this point of time, custom connector is not possible, only option to provision users to Entra ID is via Inbound API - https://learn.microsoft.com/en-us/entra/identity/app-provisioning/inbound-provisioning-api-configure-app
Let me know if you have any further questions, feel free to post back.
