intentstringrequired

When a user creates a new prescription in the UI, the system validates the medication. This validation affects both the FHIR's 'intent' and the API's 'is_approved' field. If the medication fails validation ('is_approved' = false in the API), FHIR sets the prescription's 'intent' to 'plan', indicating it needs further review.If the medication passes validation ('is_approved' = true in the API), the FHIR sets the 'intent' to 'order', signifying it's ready for fulfillment.

Possible values: [plan, order]

Example: order
