Steps
Structure the XML message using the ACORD XML envelope with a SignonRq or SignonRs for authentication context and an appropriate transaction request or response element for the business function
Declare the correct ACORD XML namespace corresponding to the version and line of business being exchanged (e.g. ACORD P&C, Life, or Health namespace URIs)
Populate the MsgStatus element in responses to communicate success, warning, or error conditions to the consuming system
Use ACORD OID (object identifier) references to link related objects within the message (e.g. linking a Policy to its Insureds and Coverages by OID)
Validate the outbound message against the ACORD XML schema (XSD) before transmission to catch structural errors before they reach the receiving system
Version the integration by including the ACORD XML version in the message header and implementing a versioned routing strategy so schema changes do not break existing consumers
Known gotchas
ACORD XML namespace URIs are version-specific and must match exactly; using a namespace from an older version while populating fields from a newer version causes schema validation failures
ACORD OID references are local to a single message instance — they are not persistent identifiers; do not store or reuse OIDs across messages as persistent business keys
Many carrier and vendor implementations use a subset of the ACORD XML schema and may not validate or accept all optional elements; always test against the specific receiver's implementation guide rather than assuming full schema compliance
