# Fathom Common Errors

## Overview

Diagnose Fathom meeting, transcript, integration, CRM-sync, and authorization issues with minimal redacted evidence and reversible fixes.

## Prerequisites

- A bounded non-sensitive reproduction, environment/version, consent/data policy, and approved diagnostic channel.

## Instructions

1. Identify affected meeting/action state and collect only opaque IDs, status, configuration version, and timing.
2. Validate scope, access, consent, mapping, and rate-limit conditions before applying a correction.
3. Test the smallest safe fix with synthetic records and document the verified result.

## Output

- A classified failure with redacted evidence, bounded remediation, owner, and verified recovery/escalation.

## Error Handling

| Condition | Safe response |
|---|---|
| Consent or access is unclear | Stop processing/sharing and verify ownership/policy. |
| CRM mapping is wrong | Pause sync and correct/test mapping before replay. |
| Duplicate action occurs | Deduplicate by stable ID; do not resend automatically. |

## Examples

For a missing follow-up, verify the synthetic meeting's action ID, consent state, mapping version, and CRM result in development. Escalate with redacted evidence if unresolved; do not inspect or share a customer recording to troubleshoot it.

## Error Reference

### 1. 401 Unauthorized

**Fix**: Regenerate API key at Settings > Integrations > API Access.

### 2. 429 Rate Limited

Limit: 60 calls per minute across all API keys.
**Fix**: Implement exponential backoff. Batch requests.

### 3. Empty Transcript

**Causes**: Meeting still processing, recording too short, or audio quality issues.
**Fix**: Wait 5-10 minutes after recording. Check recording in Fathom UI.

### 4. Missing Summary

**Cause**: AI processing not complete.
**Fix**: Poll the recording endpoint until summary is available.

### 5. Webhook Not Firing

**Fix**: Verify webhook URL in Settings > Integrations > Webhooks. Test with:

```bash
curl -X POST https://your-url.com/webhooks/fathom \
  -H "Content-Type: application/json" \
  -d '{"type": "test"}'
```

### 6. OAuth Token Expired

**Fix**: Refresh the access token using your refresh token.

## Quick Diagnostics

```bash
# Test API key
curl -s -o /dev/null -w "%{http_code}" -H "X-Api-Key: ${FATHOM_API_KEY}" \
  https://api.fathom.ai/external/v1/meetings?limit=1
```
