# Client Message Definitions

# Messages exchanged between the Client (e.g. ISV applications or Portal) and the Gateway

The protocol makes extensive use of the envelope portion of the GovTalk schema (http://www.govtalk.gov.uk/schemasstandards/schemalibrary_list.asp?subjects=11). Each document submitted to the Gateway must include a Qualifier element immediately after the Class element. Together these two elements denote the message type.

Messages issued by the client application:

- SUBMISSION_REQUEST

- SUBMISSION_POLL
- DELETE_REQUEST
- DATA_REQUEST

Messages issued by the Gateway:

- SUBMISSION_ACKNOWLEDGEMENT
- SUBMISSION_ERROR – error detected in message received from the Client
- SUBMISSION_RESPONSE/ERROR – business response/error from Target Spoke (i.e. Department)
- DELETE_RESPONSE
- DATA_RESPONSE

When submitting any message type to the Gateway it is the responsibility of the issuer (i.e. the Portal's or ISV application) to ensure each message conforms to the relevant syntactical rules for that particular type of message.
