Connecting Jira

OX supports both Jira Cloud and Jira On-Prem (Data Center / Server). For Jira Cloud, you can authenticate to Jira in one of three ways. Choose based on how you want to manage the credential and how strictly you need to scope access.

Connection method	Credential is owned by	Atlassian recommendation
Jira Cloud: Service account with OAuth 2.0	The organization	Recommended. Atlassian-preferred authentication type for service accounts.
Jira Cloud: Service account with API token	The organization	Supported. Use when OAuth is not an option for your organization.
Jira Cloud: Username + personal API token	An individual user	Legacy. Kept for existing OX deployments already using personal tokens.
Jira On-Prem (Data Center / Server)	An individual user	Self-hosted Jira; not applicable.

Use a service account where possible. A service account belongs to your Atlassian organization rather than to a specific person, so the integration keeps working when employees change roles or leave. Among the service account options, OAuth 2.0 is preferred because it exchanges short-lived access tokens at runtime instead of presenting a long-lived API token on every request.
