API Details

Edge Cases & Troubleshooting
- 280 char limit: Validate text length before posting. URLs count as ~23 chars (t.co wrapping).
- Duplicate tweet: X rejects identical tweets in quick succession. Vary the text or wait.
- Image format: Supports PNG, JPEG, GIF, WEBP. Max 5MB for images, 15MB for GIFs.
- 401 Unauthorized: Tokens expired or permissions insufficient. Regenerate at developer.x.com.
- 403 Forbidden: App may need elevated access. Check project tier.
- 429 Rate limited: Free tier allows ~50 tweets/24h. Back off and retry after
x-rate-limit-resetheader. - Missing env vars: Script should check all 4 vars exist before attempting to post. Fail with clear error.
Security
- Never log or display API credentials — mask in any error output.
- Store credentials in
secrets.envwithchmod 600, never in code or git. - Validate tweet content before posting (no accidental credential leaks).
- Review posts before sending — automated posting should have human approval.
