> AI calls keep running but your CRM stops updating. Why webhook delivery fails quietly, how to catch it in a day, and a simple daily check that prevents it.

**The most expensive AI calling failure isn't a bad call. It's good calls whose results never reach
your CRM.** The voice agent keeps calling, customers keep booking, and the webhook or integration that
updates your CRM has quietly stopped. Nobody notices until the sales team asks where the leads went.
Here is why it happens and a two-minute daily check that catches it.

## Why sync fails quietly

In one deployment, calls ran normally for days while a share of CRM updates never arrived. The calls
themselves looked fine in every review, so nothing seemed wrong. The cause was on the connection
between the two systems, not the agent.

Common causes:

- **Expired credentials.** A CRM token or API key expires or is rotated.
- **Changed URL.** The receiving endpoint moves, for example after a redeploy.
- **Renamed fields or stages.** Someone edits the CRM, and the update is rejected.
- **Rate limits.** A big campaign sends more updates per minute than the CRM accepts.
- **Slow receivers.** The endpoint takes too long to answer, and requests time out.

## The daily check

Once a day, compare:

| Number | Where |
|---|---|
| Calls completed yesterday | Voice platform call history |
| Leads updated by the agent yesterday | CRM activity or a saved report |

They won't match exactly (some calls are to numbers not in the CRM), but the ratio should be stable.
A sudden drop means sync is failing. Add this to your
[first-week monitoring routine](https://edesy.in/blog/first-week-new-ai-voice-agent-monitoring-2026) and keep it after.

## Make the receiver sturdy

If you run your own webhook endpoint:

- **Answer fast.** Return success immediately, then process the data.
- **Log every request** with the call ID, so you can match calls to updates.
- **Handle duplicates.** Use the call ID to avoid creating the same record twice.
- **Alert on errors** in your own system, for example when the CRM rejects an update.

See the [voice AI webhooks integration guide](https://edesy.in/blog/voice-ai-api-webhooks-integration-guide).

## Recovering lost updates

Call results and extracted fields stay in your call history, so a failed sync doesn't lose the data.
Export the affected calls to CSV and import them into your CRM.
The sooner you catch it, the fewer leads go cold.

## The same problem, in reverse: store webhooks for COD calls

The failure also runs the other way: the store's webhook that should *start* a call stops arriving,
and orders quietly go unconfirmed. Edesy's [COD order confirmation calls](https://edesy.in/cod-order-confirmation)
are built around this. Every incoming store event is verified, logged and de-duplicated, and can be
replayed if something needs to be re-run. Just before dialling, the order is checked again so
cancelled orders aren't called, and if the store keeps rejecting updates, calls pause so answers
don't pile up unsaved. For a store or backend of your own, the signed webhook and action URL are
described in the [custom store API](https://edesy.in/cod-order-confirmation/custom-store-api).

## Keep a simple fallback

For teams without engineering help, send results to a Google Sheet as well as the CRM. If the CRM
update fails, the sheet still has every call. See
[send AI call results to Google Sheets](https://edesy.in/blog/send-ai-call-results-to-google-sheets-2026).

## A deployment that runs this way

A rooftop solar installer in West Bengal updates its CRM after every Bengali AI call: fields, a note,
the pipeline stage, and a meeting or follow-up task. Checking that every call produces a CRM update is
part of how the setup is run. Read the
[solar installer case study](https://edesy.in/ai-voice-assistant/case-studies/solar-installer-bengali-site-surveys) and

## Frequently Asked Questions

### Why would CRM updates stop without any error?

The calls keep running on the voice side, but the step that sends results to your CRM fails: an expired token, a changed URL, a renamed field or a CRM rate limit. Nobody sees it until someone notices missing leads.

### How can I tell quickly that sync has stopped?

Compare two numbers every day: calls completed on the voice platform and records updated in your CRM. If they drift apart, sync is failing.

### What should the receiving endpoint do?

Accept the request quickly with a success response, then process it. Log every request it receives so you can match it against calls.

### Can I recover call results after sync failed?

Usually yes. Call results and extracted fields stay in your call history, so you can export them to CSV and re-import. Then fix the connection before the next campaign.

### Who should own this check?

Whoever owns the CRM. It takes two minutes a day, and it matters most in the first weeks after launch and after any change to the CRM.
