Jira OAuth refresh token invalid_grant — What it means & how to fix it
Blog post from Nango
Integrating with Jira using OAuth 2.0 (3LO) can result in token refresh failures, leading to issues like disconnected integrations and failed scheduled syncs. These failures, often indicated by an "invalid_grant" error, occur due to problems such as improper handling of rotating refresh tokens, inactivity expiry, user authorization changes, or client credential mismatches. To mitigate these issues, it is essential to persist the rotated refresh token after each refresh, manage concurrency effectively, and ensure the correct use of Atlassian's OAuth endpoints. If persistent issues arise, reauthorization may be necessary. Utilizing tools like Nango, which offers pre-built OAuth flows and automatic token management, can alleviate the complexities of maintaining OAuth integrations with Jira, allowing developers to focus on product features while ensuring reliable integration.
