Fathom Platform Help
Step 1 — Gather context
If
exists, read it first for accumulated Fathom knowledge.
-
What are you trying to do?
- A) Configure Fathom account/team/plan or understand pricing tiers
- B) Build a backend integration (API, webhooks, OAuth, SDK)
- C) Troubleshoot webhook delivery / HMAC signature verification
- D) Push transcripts/summaries into CRM, data warehouse, or Slack
- E) Troubleshoot bot joining / Google Meet security flag / Teams/Zoom capture
- F) Evaluate Fathom vs alternatives — route to
-
Which auth path?
- A) Personal API key (single user, header)
- B) OAuth 2.0 app (multi-tenant integration, Marketplace listing)
- C) Not sure yet
-
Which Fathom plan?
- A) Free
- B) Premium ($20/mo, $16 annual) — for individuals
- C) Team ($19/user/mo, 2-user min)
- D) Business ($34/user/mo, 2-user min) — CRM sync
- E) Special: Qualified Portfolio, nonprofit, Gong switchover
Skip-ahead rule: if the user's prompt already has the context, skip to Step 2.
Step 2 — Route or answer directly
| User situation | Route to |
|---|
| "Fathom vs Fireflies vs Gong vs Avoma — which should we pick" | /sales-note-taker {question}
|
| "Review this Fathom recording and score it" | /sales-call-review {question}
|
| "Manager coaching program using Fathom recordings" | /sales-coaching {question}
|
| "Build a generic Zapier/Make/n8n workflow" | /sales-integration {question}
|
| Anything Fathom-platform-specific (API, webhooks, pricing, integrations, bot behavior) | Stay here |
When routing, use the exact command:
/sales-{skill} {user's original question}
.
Step 3 — Fathom platform reference
Read references/platform-guide.md
for the full platform reference — modules, pricing tiers, integrations, plan-gated features, special programs.
Read references/fathom-api-reference.md
for verbatim API docs — endpoints, request/response schemas, OAuth flow, webhook HMAC verification, rate limits, SDK methods.
Answer using only the relevant section. Don't dump the entire reference.
Step 4 — Actionable guidance
Once you have the relevant reference content:
- For API/webhook questions — give a concrete code snippet (cURL, Python, or TypeScript based on user's stack), note the auth header or OAuth scope required, and flag the 60-req/min rate limit if the operation loops over many recordings.
- For transcript pipeline design — recommend webhook-first (create one via with and the right array) and fall back to polling
GET /meetings?created_after=...&cursor=...
for backfill/reconciliation. For OAuth apps, always use the separate GET /recordings/{id}/transcript
endpoint (the inline param is disabled for OAuth).
- For plan/pricing questions — Team/Business require a 2-user minimum and cap at max 3 CRM users per domain. CRM sync is Business-only.
- For bot/capture issues — Google Meet has recently flagged Fathom's default bot mode as a security concern; point at the "Bot-free capture" setting or native Zoom/Teams recording integration as a workaround.

Gotchas
Best-effort from research (2026-04) — review pricing tier limits and plan-gated features before quoting customers.
- API keys are user-scoped, not workspace-scoped. An admin's key only sees their own recordings plus team-shared ones — it does NOT unlock other users' unshared meetings. For team-wide access, use OAuth with each user's consent or list team members and have each authorize.
- OAuth apps cannot use or query params on . Must fetch these separately via
GET /recordings/{recording_id}/transcript
and GET /recordings/{recording_id}/summary
. Plan this into pipelines — it's 1 extra API call per meeting for OAuth builds.
- Create-webhook requires at least one of , , , or to be . An empty payload is rejected.
- Rate limit is 60 calls/minute, user-based (not key-based). Creating multiple API keys won't raise it. Bulk backfills must respect this — queue requests and handle with the header.
- Webhook signatures use Svix-style HMAC-SHA256 with three headers (, , ). The secret string starts with — strip that prefix and base64-decode the remainder before HMACing. Signed content is
${id}.${timestamp}.${raw_body}
. Verify timestamp within 5 minutes to prevent replay.
- Team/Business plans require 2-user minimum and cap at max 3 CRM users per domain. This is a common surprise when quoting small teams.
- SDK 0.0.30 introduced breaking changes in both Python and TypeScript — if pinning an older version, consult before upgrading.
- Google Meet security flag: as of late 2025/early 2026 Google Meet flags Fathom's default bot mode as a security risk and may block it. Bot-free capture (native Zoom/Meet app integration) is the workaround.

Examples
Example 1: Transcripts not arriving in Snowflake
User says: "I built a webhook receiver for Fathom but transcripts aren't showing up in Snowflake — webhooks hit but payload looks wrong"
Skill does:
- Confirms webhook was created with (otherwise payload has no transcript body)
- Walks through HMAC verification (whsec_ prefix strip, signed content format, 5-min timestamp tolerance)
- Recommends a reconcile-poll pattern: daily
GET /meetings?created_after={yesterday}
to catch any webhook deliveries that failed
- Flags the 60-req/min rate limit — if reconciliation fetches many transcripts, queue with
Result: Correct webhook payload shape + reconcile-poll fallback so no transcripts get lost.
Example 2: Multi-tenant app OAuth design
User says: "Building a SaaS that lets each customer connect their Fathom — do I use API keys or OAuth?"
Skill does:
- Recommends OAuth (API keys are user-scoped and don't scale to multi-tenant)
- Lists the OAuth steps — register at
fathom.video/marketplace_applications/new
, exchange code for tokens, implement with persistent storage (SQLite/Postgres/Redis), never use in production
- Flags that OAuth apps cannot use / on the endpoint — must fetch per-recording, so plan for N extra calls per listing page
- Notes is currently the only OAuth scope
Result: OAuth architecture plan with token storage, redirect URI, and N+1 call pattern for transcripts.
Example 3: Free tier vs Premium vs Team
User says: "We're 4 reps on Fathom free — what's the cheapest plan that gives us HubSpot sync?"
Skill does:
- HubSpot sync requires Business tier ($34/user/mo, $25 annual)
- 4 reps × $25 annual = $100/mo (not $20/mo as the free tier suggests)
- Flags the 2-user minimum and max-3-CRM-users-per-domain caps
- Suggests Qualified Portfolio Program (if they're VC-backed) — up to 2 years free
Result: Concrete monthly cost + applicable discount paths.
Troubleshooting
Webhook fires but signature verification fails
Cause: Not stripping
prefix before decoding, or comparing raw bytes instead of base64-encoded strings
Solution:
base64.b64decode(secret.split('_')[1])
— HMAC the signed content
${webhook-id}.${webhook-timestamp}.${raw_body}
(must be raw body, NOT JSON-parsed-and-re-serialized), base64-encode the digest, compare against each signature in the
header (strip version prefix
first). Verify timestamp within 5 minutes.
during bulk backfill
Cause: Exceeding the global 60 calls/minute per-user rate limit
Solution: Read the
and
headers on every response. Queue requests at 1/second (max sustainable). For OAuth apps fetching N meetings + N transcripts + N summaries, that's 3N calls — budget accordingly. Adding more API keys to the same user account doesn't help (limit is user-based, not key-based).
OAuth app transcripts are empty
Cause: OAuth apps cannot use
on
— the field silently returns null
Solution: After listing meetings, fetch transcript per recording with
GET /recordings/{recording_id}/transcript
. Same for summary — use
GET /recordings/{recording_id}/summary
. Both endpoints support async mode via
query param, which POSTs the result to your URL instead of returning inline (useful for large backfills that would otherwise time out).
