- first([1,2,3]) → 1
- last([1,2,3]) → 3
- contains([1,2,3], 2) → true
- union([1,2], [2,3]) → [1,2,3]

### Dynamic Content
```text
Reference previous action outputs:
Trigger output:
@{triggerOutputs()?['body/Title']}
Action output:
@{outputs('Get_item')?['body/Description']}
Variables:
@{variables('varEmail')}
Parameters:
@{parameters('ParamName')}
Workflow:
@{workflow()?['name']} - Flow name
@{workflow()?['run']?['name']} - Run ID
```text
## Error Handling
### Configure Run After
```text
Configure run after settings:
Action: Send error notification
Run after previous action:
☑ has failed
☑ has timed out
☐ is successful
☐ is skipped
Use cases:
- Send error notifications
- Log failures
- Retry logic
- Cleanup actions
```text
### Scope and Try-Catch
```text
Scope: Group actions for error handling
Scope: Try
- Action 1
- Action 2
- Action 3
Scope: Catch (run after Try has failed)
- Compose error details
- Send error email
- Log to SharePoint
Scope: Finally (run after Try is successful, failed, etc.)
- Cleanup actions
- Final notifications
```text
### Retry Policy
```text
Configure retry policy on actions:
HTTP action settings:
Retry Policy:
- Type: Exponential
- Count: 4
- Interval: PT10S (10 seconds)
- Minimum Interval: PT5S
- Maximum Interval: PT1H
Types:
- None: No retries
- Default: 4 retries exponential backoff
- Fixed: Fixed interval
- Exponential: Increasing intervals
```text
## Working with Data
### Parse JSON
```text
Parse JSON action:
Content: @{outputs('HTTP')?['body']}
Schema:
{
"type": "object",
"properties": {
```text
"name": {"type": "string"},
"email": {"type": "string"},
"age": {"type": "integer"}```
}
}
After parsing, access:
@{body('Parse_JSON')?['name']}
@{body('Parse_JSON')?['email']}
```text
### Compose
```text
Compose: Build complex objects
Compose action:
{
"user": "@{triggerOutputs()?['body/Author/DisplayName']}",
"date": "@{utcNow()}",
"items": @{variables('varArray')},
"approved": @{variables('varApproved')}
}
Reference: @{outputs('Compose')}
```text
### Filter Array
```text
Filter array: Filter items based on condition
From: @{variables('varItems')}
Condition:
item()?['Status'] is equal to Approved
item()?['Amount'] is greater than 1000
Result: Filtered array
```text
### Select
```text
Select: Transform array items
From: @{variables('varUsers')}
Map:
{
"fullName": @{item()?['FirstName']} @{item()?['LastName']},
"email": @{item()?['Email']},
"dept": @{item()?['Department']}
}
Result: Transformed array
```text
## Approval Workflows
### Start and Wait for an Approval
```text
Start and wait for an approval (V2):
Approval type: Approve/Reject - First to respond
Title: Purchase Request - @{triggerOutputs()?['body/Title']}
Assigned to: manager@contoso.com
Details:
Amount: @{triggerOutputs()?['body/Amount']}
Department: @{triggerOutputs()?['body/Department']}
Justification: @{triggerOutputs()?['body/Justification']}
Outputs:
@{outputs('Start_and_wait_for_an_approval_(V2)')?['body/outcome']}
@{outputs('Start_and_wait_for_an_approval_(V2)')?['body/responses'][0]['comments']}
Condition:
If outcome is equal to "Approve"
- Update status to Approved
Else
- Update status to Rejected
```text
### Custom Approval Responses
```text
Approval type: Custom responses - Wait for one response
Response options:
- Approve
- Request More Info
- Reject
Switch on outcome:
Case "Approve":
- Proceed with request
Case "Request More Info":
- Send to requester for details
- Create follow-up task
Case "Reject":
- Update and notify
```text
## Testing and Monitoring
### Test Flow
```text
Testing methods:
1. Test button:
- Test with manual trigger
- Test with recent trigger data
- Test with custom data
2. Flow Checker:
- Validates flow before save
- Checks for errors
- Identifies warnings
3. Run history:
- View past runs
- Check duration
- Review inputs/outputs
- Debug failures
```text
### Monitor Flow Runs
```text
Flow run details:
Status:
- Succeeded
- Failed
- Cancelled
- Running
Duration: Time to complete
Actions:
- Expand each action
- View inputs
- View outputs
- Check status
Resubmit:
- Resubmit failed runs
- Fix and retry
```text
### Analytics
```text
Analytics dashboard:
Metrics:
- Total runs
- Success rate
- Failure rate
- Average duration
Filters:
- Date range
- Status
- Trigger type
Identify:
- Performance issues
- Common failures
- Usage patterns
```text
## Best Practices
### Performance Optimization
```text
1. Minimize API calls:
- Batch operations
- Use OData filters
- Cache data in variables
2. Parallel branches:
- Run independent actions in parallel
- Configure run after appropriately
3. Pagination:
- Enable pagination for large datasets
- Set appropriate thresholds
4. Avoid infinite loops:
- Add loop counters
- Set do until limits
- Use terminate action
5. Efficient expressions:
- Use simple expressions
- Avoid nested functions
- Cache complex calculations
```text
### Error Handling
```text
1. Always handle errors:
- Configure run after
- Use try-catch pattern
- Send error notifications
2. Provide context:
- Include flow name
- Log inputs
- Capture error messages
3. Implement retries:
- Use retry policies
- Handle transient failures
- Exponential backoff
4. Graceful degradation:
- Have fallback options
- Don't block on errors
- Continue where possible
```text
### Security
```text
1. Use managed identities:
- Azure services connections
- Avoid storing credentials
2. Secure inputs/outputs:
- Mark sensitive actions
- Hide in run history
3. Minimize permissions:
- Principle of least privilege
- Connection references
4. Audit trails:
- Log important actions
- Track approvals
- Maintain records
Architecture Decision and Tradeoffs
When designing process automation solutions with Power Automate, consider these key architectural trade-offs:
| Approach | Best For | Tradeoff |
|---|---|---|
| Managed / platform service | Rapid delivery, reduced ops burden | Less customisation, potential vendor lock-in |
| Custom / self-hosted | Full control, advanced tuning | Higher operational overhead and cost |
Recommendation: Start with the managed approach for most workloads and move to custom only when specific requirements demand it.
Validation and Versioning
- Last validated: April 2026
- Validate examples against your tenant, region, and SKU constraints before production rollout.
- Keep module, CLI, and SDK versions pinned in automation pipelines and review quarterly.
Security and Governance Considerations
- Apply least-privilege access using RBAC roles and just-in-time elevation for admin tasks.
- Store secrets in managed secret stores and avoid embedding credentials in scripts or source files.
- Enable audit logging, data protection policies, and periodic access reviews for regulated workloads.
Cost and Performance Notes
- Define budgets and alerts, then monitor usage and cost trends continuously after go-live.
- Baseline performance with synthetic and real-user checks before and after major changes.
- Scale resources with measured thresholds and revisit sizing after usage pattern changes.
