1. Verify the validity of access token

   • in case of error - return 401 (“Invalid access token”) in case of validation fails

2. Verify that token is not expired

   • in case of error - return 401 (“Invalid access token”)

3. Check user scopes in order to perform this action (scope = 'medication_request_request:write')

   • return 403 (“Your scope does not allow to access

   this resource. Missing allowances: medication_request_request:write”) in case of invalid scope(s

   • this resource. Missing allowances: medication_request_request:write”) in case of invalid scope(s)

4. If BLOCK_UNVERIFIED_PARTY_USERS is true, then check party's data match following condition: verification_status != NOT_VERIFIED or (verification_status = NOT_VERIFIED and updated_at <= current_date - UNVERIFIED_PARTY_PERIOD_DAYS_ALLOWED):

   • in case not match - return 403 ("Access denied. Party is not verified")

1. Generate human readable number for receipt (See specs)

   Code Block

   Structure number XXXX-1234XXXX-5678-9012-345-C XXXX-XXXX, where: - XXXX - series: numbers + only some letters (A, E, H, K, M, P, T, X) - first block - always "0000" for medication requests - 1234-5678-9012-345 - randomly generated numbers - C - checksum: Should be calculated using the Damn algorithm or Verhoeff algorithm pattern: ^[0]{4}-[#{symbols}]{4}-[#{symbols}]{4}-[#{symbols}]{4} - example: 0000-TP42-M36M-H6TH After new Request number was generated we should check that it is unique in the DB (entity: medication_request + medication_request_request), if Request number is already reserved - generate new

2. Generate verification_code for MPI.person_authentication_methods == OTP or OFFLINE

   Code Block
   Structure code 1234, where: - 1234 - randomly generated numbers

...

1. set:

   1. dispense_valid_from = created_at

   2. dispensed_valid_to = dispensed_valid_from + dispense_period

2. Fill 'data' structure for Response & save in IL.medication_request_requests

   1. If encounter is present in the request context then based on it - fill the IL.medication_request_requests.context_episode_id

3. Fill separately

   1. data_employee_id,
      data_intent,
      data_based_on_care_plan_id,
      data_based_on_activity_id,
      data_context_id,
      data_patient_id,
      data_legal_entity_id

Update based_on

1. If the medication request request is based on activity with quantity - set remaining_quantity for the activity which was calculated at validation Create Medication Request: Validate based_on (p. 2.d.1 )
