# HL7 v2.x Integration

# HL7 v2.x Integration {#ariaid-title1}

Release version: Australia  
Updated June 30, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
HL7 v2.x Integration enables ServiceNow to receive, log, parse,
and act on HL7 v2.x messages sent by hospital integration engines, without requiring
custom scripting on either side.
Health Level Seven (HL7) v2.x is the most widely deployed healthcare messaging standard. Hospital systems, including EHR systems such as Epic, use HL7 v2.x messages to communicate clinical and operational events. These include
patient admissions, discharges, and transfers (ADT).

HL7 v2.x Integration provides three core capabilities: message reception and
acknowledgment, configurable parsing, and no-code workflow integration. Integration
engines handle transport (MLLP, HTTPS). ServiceNow manages message reception,
logging, parsing, and workflow triggering.

## Get started {#hl7-integration-overview__hl7-integration-get-started}

* [How HL7 integration works in
  ServiceNow](https://www.servicenow.com/docs/sxs_tKJG32Q3UccQ1VUoJA "HL7 v2.x messages flow through four stages in ServiceNow: reception and acknowledgment, message logging, parsing, and workflow execution.")
* [HL7 message log](https://www.servicenow.com/docs/9nHpg89o8H7Eb7Qu_sdnwg "The HL7 message log stores every inbound HL7 v2.x message received by ServiceNow, along with its ACK response, extracted metadata, and processing status.")
* [Parser configurations](https://www.servicenow.com/docs/bUw~_oh1FG42A0a0ULvgFg "Parser configurations define which HL7 segments and fields ServiceNow extracts from a received message. Each value is written to an output path in the message log's parsed data.")
* [Connect your
  integration engine to ServiceNow](https://www.servicenow.com/docs/a8R4NpMwbpDLcg9ZaxyEKw "Configure your integration engine to POST HL7 v2.x messages to the ServiceNow HL7 endpoint so that messages are received, logged, and acknowledged automatically.")
* [Clone and customize a
  parser configuration](https://www.servicenow.com/docs/iyAwceTeKGdQNVJjKNPrKw "Clone a demo parser configuration to create a customizable copy that you can modify for hospital-specific field variations and relabeling.")
* [Test a parser
  configuration with a sample payload](https://www.servicenow.com/docs/myVELtkJpqs3biyd67YJPQ "Run a parser configuration against a sample HL7 v2.x message to confirm that it extracts the segments and fields you expect before you use it in a workflow. The parsed values appear on the configuration's field maps.")
* [View and filter the HL7
  message log](https://www.servicenow.com/docs/v4vDAD3LIlR14edLfJba7Q "Use the HL7 message log to review inbound messages, inspect raw message content and ACK responses, and filter by status, message type, or sending facility.")
* [Investigate
  failed HL7 messages](https://www.servicenow.com/docs/qGkVQ4wj33KgMepXWzLYZw "Identify and diagnose inbound HL7 messages that resulted in an application error (AE), application rejection (AR), or failed processing status.")
* [Components installed
  with HL7 v2.x Integration](https://www.servicenow.com/docs/FfHIVa3by0eNAvwON3EVPA "Several types of components are installed with activation of the HL7 v2.x Native Integration plugin, including tables, user roles, and Flow Designer actions.")
* [HL7 message log
  fields](https://www.servicenow.com/docs/cgA1fts2jg6DlBBveEewcQ "Field reference for the HL7 Message Log table (sn_hl7_v2_message_log).")
* [Parser configuration
  fields](https://www.servicenow.com/docs/LVkSjaF~~m4Wcmaljweteg "Field reference for the parser configuration, parser segment, and field map tables that define how the HL7 parser engine extracts message data.")
* [HL7 ACK codes](https://www.servicenow.com/docs/c5bRe3e4qYeAD5FANpJ65A "ServiceNow returns one of three HL7 acknowledgment codes in the MSA segment of every ACK response. The code indicates whether the message was accepted, rejected at the application level, or resulted in an error.")
