Please see Service request (Referral) state model and Dummy Recall Service Request for more details

Request structure

See on Apiary

Example:

{
  "signed_data": "ew0KICAicGVyaW9kIjogew0KIC..."
}

Authorize

• Verify the validity of access token

  • Return (401, 'unauthorized') in case of validation fails

• Verify that token is not expired

  • in case of error - return (401, 'unauthorized')

• Check user scopes in order to perform this action (scope = 'service_request:write')

  1. Return (403, 'invalid scopes') in case of invalid scope(s)

Request to process the request using a token in the headers

Headers

Наприклад:

• Content-Type:application/json

• Authorization:Bearer: {{access_token}}

• api-key: {{secret}}

Request data validation

Validate legal entity

• Check legal entity type: it has to be in me_allowed_transactions_le_types config parameter, has status = active and nhs_verified = true

  • in case of error return 409 "Action is not allowed for the legal entity"

Validate digital signature

Decode content that is encrypted in an electronic digital signature.
Use Digital signature WS. Method checks digital signature and returns result.
See service specification

1. Ensure that digital signature is valid

1. Validate that requester of service request is a current user

2.1. Get token metadata

• Extract user_id, client_id, client_type

2.2. Determine the party_id associated with this user_id

SELECT pu.party_id FROM party_users pu
WHERE pu.user_id = :user_id;

2.3. Determine employees related to this party_id in current MSP

SELECT e.id FROM employees e WHERE e.party_id = :party_id
AND e.legal_entity_id = :client_id;

2.4 Ensure that $.requester.identifier.value matches with user employees

1. Validate that DS belongs to the requester of encounter

3.1. Determine the party_id associated with requester ($.requester.identifier.value)

SELECT p.tax_id FROM employees e, parties p WHERE e.party_id = p.id
AND e.id = :requester;

Validate request using JSON Schema

Return 422 with the list of validation errors in case validation fails

Validate permission to recall

Only doctor who signed this service request is able to recall this service request

Covered by DS validation (see Validate digital signature p.2)

Validate transition

Only active service request can be recalled

1. Get current service request status

   1. Check that status in ('active')

      1. in case of error - return 409 error ('Service request in status %status% cannot be recalled')

Validate recall reason

1. Validate $.status_reason is a value from eHealth/service_request_recall_reasons dictionary

   1. in case of error - return 422 ("value is not allowed in enum")

Validate content

Signed content must match with service request in DB in order to be recalled

1. Render service request from DB

2. Exclude $.status_reason and $.explanatory_letter from signed content

3. Compare rendered service request and signed content

   1. In case both object doesn't match - return 422 ('Signed content doesn't match with previously created service request')

Processing

Service logic

1. Save signed content to media storage

2. Update service request status to Recalled (update also updated_at, updated_by)

3. Write record to status history

4. Send SMS to patient (if authentication_method_current == SMS)

   1. Template - TBD

5. Async! Revoke all approvals made by this service request
