HL7 Writeback Connector

Version 3



HL7 is an EDI standard for healthcare applications and providers for the exchange, integration, sharing, and retrieval of electronic health information. Health Level Seven or HL7 refers to a set of international standards for transfer of clinical and administrative data between software applications used by various healthcare providers. Use Domo's HL7 Writeback connector to convert the DOMO dataset data into an HL7 message. Once the HL7 messages are constructed for all the items in the dataset, the connector will create a file that will get SFTP'ed to a specific location. 

You export Domo data to HL7 in the Data Center. This topic discusses the fields and menus that are specific to the HL7 Writeback connector user interface. General information for adding DataSets, setting update schedules, and editing DataSet information is discussed in Adding a DataSet Using a Data Connector.


To configure this connector and create a DataSet, you must have the following:

  • The hostname used to connect to SFTP server

  • The port number used to connect to SFTP server

  • The username and password for the SFTP server

Configuring the Connection

This section enumerates the options in the Credentials and Details panes in the HL7 Writeback Connector page. The components of the other panes in this page, Scheduling and Name & Describe Your DataSet, are universal across most connector types and are discussed in greater length in Adding a DataSet Using a Data Connector.

Credentials Pane

This pane contains fields for entering credentials to connect to your HL7 dataset. The following table describes what is needed for each field:  



Hostname Enter the hostname used to connect to SFTP server.
Port Enter the port number used to connect to SFTP server.
Username Enter the username of the SFTP server.
Password Enter the password of the SFTP server.
SSH Private Key Enter the SSH private key (DES or RSA), in PEM format.
Passphrase Enter the SFTP server passphrase.

You can use the same account any time you go to set up a new Domo-HL7 connection. You can manage connector accounts in the Accounts tab in the Data Center. For more information about this tab, see Managing User Accounts for Connectors.

Details Pane

This pane contains a number of fields for specifying your data and indicating where it's going.



Path Enter the SFTP file location.
Select Filename Select whether you would like to use the input dataset guide or enter the output filename manually.
Filename Enter the output file name.

Other Panes
