Best practices

Use these practices to build secure, reliable, and maintainable Camunda–ServiceNow integrations.

Manage credentials securely

• Store and manage ServiceNow credentials using Camunda secrets.
• Never hardcode usernames or passwords in connector configurations or BPMN models.
• Reference secrets with the {{secrets.<name>}} syntax in connector fields.
• Apply this consistently across all ServiceNow connectors to maintain a unified security model.

Reuse variables effectively

• Map ServiceNow sys_id values to top-scope process variables in your BPMN process.
• Use these variables for:

Action	Purpose
Lookup	Retrieve existing records reliably
Update	Modify records without additional queries
Delete	Remove records when needed
Correlation	Tie records to notifications or process events

Example:

= incidentResponse.body.sys_id
