# Unhandled Error Capture

> Capture Flow faults and unhandled Apex exceptions via email inbound.

## How it works

When Salesforce encounters an unhandled Apex exception or a Flow fault, it sends an email notification. Zentien provides each org with a unique inbound email address. When you add this address to your org's notification settings, those emails flow directly into Zentien — no polling, no delay.

## Find your inbound address

Go to **Orgs** in the Zentien dashboard. Your inbound address is shown next to your connected org:

```
{orgId}@zentienapp.com
```

Click the **Copy** button to copy it to your clipboard.

## Configure in Salesforce

Add your inbound address in two places:

### Apex Exception Email

Captures unhandled exceptions from Apex code, batch jobs, and scheduled jobs.

1. Go to **Setup** → search **"Apex Exception Email"**
2. Under **External Email Addresses**, add your Zentien inbound address
3. Click **Save**

### Flow and Process Error Email

Captures Flow fault path errors and Process Builder failures.

1. Go to **Setup** → search **"Process Automation Settings"**
2. Find the **Send Process or Flow Error Email** field
3. Add your Zentien inbound address
4. Click **Save**

## Test it

To confirm the setup is working, trigger a test error and check your Zentien dashboard:

1. In Zentien, go to **Orgs** and note your inbound address
2. In your Salesforce org, run any code that throws an unhandled exception
3. Within 1–3 minutes, the error should appear in **Zentien → Errors**

<Note>
  Salesforce suppresses duplicate exception emails when the same class throws the same error repeatedly within a short window. If you don't receive an email after testing, wait a few minutes and try again with a different error. See the [FAQ](/reference/faq) for more details.
