# completeServiceAuthorization

> Finalize a service authorization after the user has completed the OAuth flow in the third-party service. For most services, pass the serviceAuthorizationId returned by startServiceAuthorization. For Jira, also provide the jira field with the refreshToken and siteId obtained from Atlassian's OAuth callback. On success, the authorization transitions to CONNECTED status and is ready for use.
