snow-update

info

This promotion step is only available in Kargo on the Akuity Platform, versions v1.9.0 and above.

This page is for snow-update step. You can update a ServiceNow record using this step. Check below for other ServiceNow promotion steps.

ServiceNow integration for kargo is a group of promotion steps:

1. snow-create
2. snow-update
3. snow-delete
4. snow-query-for-records
5. snow-wait-for-condition

These steps provide a comprehensive integration with ServiceNow, allowing you to create, update, delete, query for records, and track promotion workflows. This is particularly useful for maintaining traceability between your promotion processes and project management activities.

All the steps above support different record types in ServiceNow including managing Change Requests, Incidents, Problems etc.,. This integration also provides condition tracking through snow-wait-for-condition, making it a powerful tool for promotion workflows that require coordination with project management systems.

snow-update step supports two APIs:

1. Change Management API

This API is used primarily for managing Change Requests.

Official documentation is available here.

URL format: /api/sn_chg_rest/{api_version}/change/{change_sys_id}/task/{task_sys_id}

2. Table API

This API is used for managing Incidents, Problems, and other record types.

Official documentation is available here.

URL format: /api/now/{api_version}/table/{tableName}/{sys_id}

Using the API

Most of the time you cannot use the field labels you see in the ServiceNow UI as keys in the REST API. For example, if you want to set the value for the “Short description” field:

You can't use Short description in the REST API. You need to use short_description as the key and set the value via REST API parameters. To find the correct key for a field, right-click on the field and click Configure Dictionary:

column_name is the key:

To see choices available for a particular field e.g., State, right click on the field and click on Show Choice List to see the available choices for use in the steps:

For example New is -1 and Scheduled is -2

Configuration

Credentials

All ServiceNow operations require proper authentication credentials stored in a Kubernetes Secret.

Name	Type	Required	Description
credentials.secretName	string	Y	Name of the Secret containing the ServiceNow credentials in the project namespace.
credentials.type	string	Y	Type of ServiceNow credentials to use for authentication (either api-token or basic).

For credentials.type: api-token the referenced Secret should contain the following keys:

• apiToken: ServiceNow API Token (see this blog post for how to create an API token in ServiceNow).
• instanceURL: Your ServiceNow instance URL.

For credentials.type: basic the referenced Secret should contain the following keys:

• username: Username of the ServiceNow user (you may want to create a user specifically for this integration).
• password: Password of the ServiceNow user (for how to set the password for a user, see this).
• instanceURL: Your ServiceNow instance URL.

Record

Name	Type	Required	Description
parameters	string map	Y	Parameters/fields of the record.
tableName	string	Y	Table name of the record type you want to update (e.g., incident, problem, change_request).
ticketId	string	Y	Ticket ID (sys_id) of the record you want to update.
template	object	N	Specify this to update a Change Request using the Change Management API (if omitted, the Table API is used).
template.type	string	Y/N	Template type (standard, emergency, or normal). Required if template is specified; otherwise optional.

Output

This step does not produce any output.

Example

This example updates a Change Request using the Change Management API:

steps:
  - as: snowupdate
    config:
      credentials:
        secretName: snow-creds
        type: api-token
      parameters:
        short_description: Update deployment for ${{ vars.imageRepo }}:${{
          imageFrom(vars.imageRepo).Tag }} to done
      tableName: change_request
      template:
        type: standard
      ticketId: 9d41c061c611228700edc88b231ec47c
    uses: snow-update

This example updates an Incident using the Table API:

steps:
  - config:
      ticketId: ${{ task.outputs.snowquery.sys_id }}
      credentials:
        secretName: snow-creds
        type: api-token
      parameters:
        short_description: Update deployment incident for ${{ vars.imageRepo }}:${{ imageFrom(vars.imageRepo).Tag }} to resolved
      tableName: incident
    uses: snow-update

This example updates a Change Request using the Table API (notice how the template field is omitted):

steps:
  - as: snowupdate
    config:
      credentials:
        secretName: snow-creds
        type: api-token
      parameters:
        short_description: Update deployment incident for ${{ vars.imageRepo }}:${{
          imageFrom(vars.imageRepo).Tag }} to resolved
      tableName: change_request
      ticketId: ${{ task.outputs.snowquery.sys_id }}
    uses: snow-update

Different E2E Workflows

These examples demonstrate the different steps supported for ServiceNow integration.
