Provider Access API

The Da Vinci PDex Provider Access API lets a provider attest to a treatment relationship with a payer's members and pull their clinical data in bulk. The flow has two stages:

1. Match members. Submit a batch of patient demographics + coverage + treatment-relationship attestation. The payer returns one or more Group resources identifying matched members, members the payer could not match, and members who have opted out of provider data sharing.
2. Export data. Use the MatchedMembers Group ID with $davinci-data-export to retrieve the patients' clinical data as ndjson via the FHIR Bulk Data async pattern.
