Hello,
Thank you for your question!
Once you create your Patients and Practitioners and add them to your attribution roster (Group), you can run a bulk export against that roster.
DPC will then return the data for those beneficiaries — including their Patient, EOB, and Coverage resources. If you only need one beneficiary, you can scope the export to that patient using the Patient/$everything endpoint.
So you do create the Patient and Practitioner records to establish the roster, but the claims data itself is served back to you — you don't seed or import that.
Let us know if you have more questions!
Best,
The DPC API team
