+# Issue Response: "Unexpected error occurred when calling the XRM api" in Sync Flows
+
+## Issue Pattern
+
+Users report that sync flows (particularly **Admin | Sync Template v4 (Flows)**, **Admin | Sync Template v4 (Apps)**, or other inventory flows) are failing with the error:
+
+```
+Action 'List_Flows_as_Admin_(V2)' failed
+
+Request to XRM API failed with error: 
+'Unexpected error occurred when calling the XRM api'
+```
+
+## Quick Triage
+
+This is a **known, transient error** related to:
+- ✅ API throttling (most common)
+- ✅ Service protection limits
+- ✅ Temporary connectivity issues
+- ✅ Authentication token expiration

+### Response to User
+
+Thank you for reporting this issue! The error you're seeing is a known, transient error that typically resolves with a simple retry.
+
+#### Quick Fix (Success Rate: ~70%) ✅
+
+**Step 1: Resubmit the Flow**
+1. Go to Power Automate in your CoE environment
+2. Find the failed flow run
+3. Click **Resubmit** (top-right button)
+4. Monitor the resubmitted run
+
+This error is often temporary and resolves on retry.
+
+#### If Resubmit Doesn't Work
+
+**Step 2: Enable Inventory Delays**
+
+This reduces the rate of API calls to avoid throttling:
+
+1. Go to Power Apps → CoE environment → Solutions
+2. Open **Center of Excellence - Core Components**
+3. Navigate to **Environment Variables**
+4. Find `admin_DelayObjectInventory`
+5. Set **Current Value** = `Yes`
+
+**Impact**: This will significantly reduce throttling errors, but inventory will take longer to complete.
+
+**Step 3: Verify Full Inventory Mode**
+
+Ensure you're not running in full inventory mode (which processes ALL objects and can trigger throttling):
+
+1. In Environment Variables, find `admin_FullInventory`
+2. Verify **Current Value** = `No` (unless you're doing initial setup or troubleshooting)
+
+**Note**: Only use full inventory mode for:
+- Initial CoE setup
+- After long periods without sync
+- Troubleshooting missing data
+
+#### Detailed Troubleshooting Guide
+
+For comprehensive information about this error, see:
+
+📖 **[Sync Flows XRM API Errors Troubleshooting Guide](./troubleshooting/sync-flows-xrm-api-errors.md)**
+
+This guide includes:
+- Root cause analysis
+- All configuration options
+- Advanced troubleshooting steps
+- Preventive measures
+
+### Understanding the Error
+
+The "Unexpected error occurred when calling the XRM api" is a **generic error message** from the Power Platform Admin connectors. It typically indicates one of these conditions:
+
+- 🔄 **API throttling / Service protection limits** (most common)
+- 🌐 **Transient network or service issues**  
+- 🔑 **Authentication token expiration**
+- 📊 **Dataverse service limits**
+
+### Built-in Protection
+
+The CoE Starter Kit sync flows **already include retry logic** to handle transient errors:
+
+- ✅ Retries up to **30 times**
+- ✅ Uses **exponential backoff** (waits longer between each retry)
+- ✅ Starts with **30-second intervals**
+
+However, if the underlying issue persists (e.g., sustained throttling), the flow will eventually fail after exhausting all retries.
+
+### When to Follow Up
+
+If the error persists after:
+- Resubmitting the flow multiple times
+- Enabling `admin_DelayObjectInventory`
+- Waiting 24 hours
+
+Please provide:
+1. CoE Starter Kit version
+2. Which sync flow is failing (Flows, Apps, Connectors, etc.)
+3. Approximate number of environments in your tenant
+4. Current environment variable settings:
+   - `admin_DelayObjectInventory`
+   - `admin_FullInventory`
+   - `admin_InventoryFilter_DaysToLookBack`
+5. Screenshot of the flow run error
+6. Frequency (every run, occasional, specific times)

+
+## Resolution Statistics
+
+Based on community feedback:
+- **~70%** of cases resolve on first resubmit
+- **~20%** resolve after enabling `admin_DelayObjectInventory`
+- **~10%** require additional investigation (usually related to tenant size, service health, or connection issues)
+
+## When to Escalate
+
+Escalate if:
+- User has tried all recommended steps
+- Error persists for >3 days
+- Multiple sync flows are affected
+- Same environment consistently fails
+- Service health shows no incidents
+
+## Related Issues
+
+Search GitHub for similar patterns:
+- Issues with "XRM API" in title
+- Issues with sync flow failures
+- Issues tagged with `bug` and `core-components`
+
+## Prevention Tips for Users
+
+Share these preventive tips:
+1. Use **incremental mode** (default) for daily operations
+2. Run **full inventory** only when needed (initial setup, quarterly reviews)
+3. Enable `admin_DelayObjectInventory` for large tenants (>500 environments)
+4. Stagger sync flow schedules to avoid simultaneous runs
+5. Monitor service health before running full inventory
