Harness Change Authoring API

The Change Authoring API from Harness — 3 operation(s) for change authoring.

GitHub OpenAPI

Operations 3

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

POST /v1/orgs/{org}/projects/{project}/change-authoring-event Record a pipeline run from an AI change chat · Create change authoring execution event #
Ask an LLM
“How is a pipeline run from the LLM change authoring chat recorded?”
“Which IDs link a chat conversation to the pipeline execution it triggered?”
Tell an agent
Record that chat {conversationId} ran pipeline {pipelineIdentifier} (run {pipelineExecutionId}) on schema {schemaIdentifier} in {org}/{project}.
Log a change authoring event for chat {conversationId} and execution {pipelineExecutionId}, pipeline {pipelineIdentifier}, schema {schemaIdentifier}.
POST /v1/orgs/{org}/projects/{project}/dbschema/{dbschema}/changesets/existence Check which Liquibase changesets a schema already has · Check changeset existence for a schema #
Ask an LLM
“Have these Liquibase changeset IDs already been applied to my database schema?”
“Is changeset matching done by ID only?”
Tell an agent
Check whether changesets {changeSets} exist for schema {dbschema} in org {org} project {project}.
Tell me which of {changeSets} are already known for schema {dbschema}.
POST /v1/orgs/{org}/projects/{project}/llm-authoring/execute-pipeline Run a validate-and-preview pipeline for a changeset · Execute an LLM-authoring validate-and-preview pipeline #
Ask an LLM
“Can I validate and preview a Liquibase changeset from the AI chat before applying it?”
“Is running the LLM authoring pipeline billable?”
Tell an agent
Validate and preview changeset {changeset} on schema {schemaId} instance {instanceId} for conversation {conversationId} in org {org} project {project}.
Run the default preview pipeline for changeset {changeset} on schema {schemaId}, instance {instanceId}, chat {conversationId}.
