External message has child external message

The Teamwork Graph API is available through Forge's Preview release phase.

Preview features are available to all users and receive the same level of support as generally available features. Schemas, fields, and behavior may still change before general availability (GA), and breaking changes are subject to a minimum 1-month deprecation notice, announced in the Teamwork Graph changelog.

To review the current limitations, see Limitations and considerations.

To share feedback or report an issue, visit the Atlassian developer community.

The ExternalMessageHasChildExternalMessage relationship represents the hierarchical link between messages, where one message is a reply or thread response to another. It allows you to:

Retrieve child messages (replies) to a specific parent message
Find the parent message of a specific message reply
Build and traverse message threads and conversations

Relationship type: Canonical

From object types	To object types
External message - `ati:cloud:graph:message`	External message - `ati:cloud:graph:message`

Cypher

We recommend sending parameterized Cypher queries as below instead of embedding the parameters directly in the query string. This approach will help ensure better performance.
