Recovery playbook

One page for diagnosing and recovering from any VoxBurst posting failure. Find your situation and follow the steps.


1. Validation error before the post is created (status 400)

The post was never created. The API returned an error immediately.

Diagnose: Read the error message — it usually names the field and what’s wrong.

validate_content( content: "your caption", platforms: ["INSTAGRAM"] )

Common causes:

ErrorFix
CONTENT_TOO_LONGShorten the caption to the platform’s limit
MEDIA_REQUIREDAdd mediaUrls or mediaIds (required on Instagram)
CONTENT_TYPE_REQUIREDAdd contentType: "IMAGE" (required on Instagram)
CONTENT_TYPE_NOT_SUPPORTEDChange contentType — e.g. Instagram does not support STORY
ACCOUNT_NOT_FOUNDCheck the accountId value from list_accounts
Invalid scheduledForUse ISO 8601 format in UTC: 2026-06-01T15:00:00Z

2. Post created but status stays pending or publishing

The post exists in VoxBurst but publishing hasn’t completed.

Check status:

get_post(postId: "post_abc123")

What to do:

  • pending for less than 5 minutes: normal — posts go through a scheduling queue. Wait and re-check.
  • pending for more than 10 minutes: check the VoxBurst dashboard for queue issues.
  • publishing for more than 5 minutes: the publish attempt is in flight. Wait another minute, then check again.

3. Post status is failed (all platforms failed)

get_post(postId: "post_abc123")

Read platforms[].error for each platform to find the reason. Then:

Step 1 — Retry (for transient errors)

retry_post(postId: "post_abc123")

VoxBurst automatically retries up to 3 times with exponential backoff. If the failure was transient (network error, rate limit), this resolves it.

Step 2 — Fix and resubmit (for content/media errors)

If the error was caused by invalid media or caption:

# Get the postPlatformId from get_post's platforms[] array curl -X POST https://api.voxburst.io/v1/posts/post_abc123/platforms/pp_xyz789/fix \ -H "Authorization: Bearer vb_live_xxxxxxxxxxxxx" \ -d '{ "mediaUrl": "https://cdn.example.com/corrected-image.jpg" }'

This resets the retry counter and resubmits with corrected media.

Common platform errors and fixes:

platforms[].errorCauseFix
MEDIA_REJECTED / error 9004Instagram rejected image formatRe-upload or use /fix with a fresh URL
ASPECT_RATIO_INVALIDImage ratio outside 4:5–1.91:1Re-crop and re-upload
CONTENT_TOO_LONGCaption exceeded the platform limitShorten via update_post then retry
ACCOUNT_DISCONNECTEDOAuth token expiredRe-connect account in VoxBurst settings
QUOTA_EXCEEDEDYouTube daily limit hitWait until midnight Pacific, then retry
DUPLICATE_CONTENTTwitter rejected identical tweetCall update_post to change caption slightly
INSUFFICIENT_PERMISSIONSMissing required page permissionsRe-connect account and grant required scopes

4. Post status is partial (some platforms succeeded, some failed)

Instagram published but Twitter failed. VoxBurst records this as partial.

get_post(postId: "post_abc123")

Look at platforms — entries with status: "published" succeeded, entries with status: "failed" need attention.

Retry only the failed platforms:

retry_post(postId: "post_abc123")

retry_post re-queues only failed platforms. Platforms that already published are never re-posted.

If a platform shows retryCount: 3 — it has exhausted automatic retries. Use the REST /fix endpoint to reset it:

curl -X POST https://api.voxburst.io/v1/posts/post_abc123/platforms/pp_failed_platform/fix \ -H "Authorization: Bearer vb_live_xxxxxxxxxxxxx"

5. Media processing failure

The media upload succeeded but the file failed processing.

curl https://api.voxburst.io/v1/media/media_abc123 \ -H "Authorization: Bearer vb_live_xxxxxxxxxxxxx"

Look for "status": "FAILED" and validationResults for the reason.

Common causes and fixes:

validationResults errorFix
Unsupported codecRe-encode video to H.264 with AAC audio
Resolution too lowUse minimum 720p for video
File corruptedRe-download or re-export the file
Duration too longTrim to within platform limits

Upload a corrected file and get a new mediaId before retrying the post.


6. Account permission / auth failure

get_post(postId: "post_abc123")

platforms[].error will mention ACCOUNT_DISCONNECTED, INVALID_TOKEN, INSUFFICIENT_PERMISSIONS, or similar.

Fix:

  1. Go to VoxBurst app → Settings → Connected Accounts
  2. Find the affected account
  3. Disconnect and re-connect it
  4. Make sure to approve all requested permissions during re-connection

Then retry the post.


7. Retry vs recreate — when to do each

SituationAction
Transient error (network, rate limit)retry_post
Wrong media (bad aspect ratio, format)/fix with corrected mediaUrl
Wrong caption (too long, wrong content)update_post then retry_post
Wrong account targetedCannot change after creation — delete and create a new post
Platform exhausted retries (retryCount=3)REST /fix to reset counter
Wrong contentTypeCannot change after creation — delete and create new

8. Delete and start over

Sometimes the simplest fix is to delete the post and create a fresh one:

delete_post(postId: "post_abc123")

Only draft, scheduled, failed, and partial posts can be deleted through the MCP tool. Published posts cannot be deleted.

Then create a new post with the corrected parameters.
