Monitor partner API usage with Slack, Jira and Gmail alerts

Description

Smart Partner API Usage Monitoring with Slack, Jira & Gmail Alerts

This workflow monitors partner API usage in real time and triggers alerts based on usage thresholds. It validates incoming data, calculates usage percentage and routes actions using a Switch node. Slack notifications are sent at 80%, Jira tickets are created at 90% and critical alerts (Email + Jira + Slack) are triggered at 100%.

Quick Implementation Steps

Import the workflow into n8n
Configure the Webhook node and test with sample data
Add credentials for Slack, Jira and Gmail
Update Slack channel ID, Jira project and email recipient
Activate the workflow
Send test payloads to verify all alert levels

What This Workflow Does

This workflow helps monitor partner API usage automatically and ensures timely alerts when usage reaches defined thresholds. It starts by receiving usage data through a webhook, validating the payload and calculating the usage percentage based on quota and consumption values.

Once calculated, the workflow routes the data using a Switch node. At 80% usage, it sends an early warning Slack notification. At 90%, it escalates by creating a Jira ticket and notifying via Slack. When usage reaches 100%, it triggers a critical alert by sending an email, creating a Jira ticket and sending a Slack notification.

This approach ensures better visibility, timely action and helps prevent service disruption.

How It Works & Setup Guide

Setup Steps

Webhook Setup
Configure the Incoming Partner Usage Data node
Accept POST requests
Required fields:
partner_id
partner_name
quota
consumed
timestamp

Validate Payload
The workflow checks for missing fields and invalid values

Calculate Usage
Calculates usage percentage from quota and consumed values
Stops execution if usage is below 80%

Switch Routing
Routes workflow based on usage:
80% → Slack alert
90% → Jira + Slack
100% → Gmail + Jira + Slack

Configure Integrations
Slack: Set channel ID
Jira: Set project and issue type
Gmail: Set recipient email

Test Workflow
Send sample data to webhook
Verify all alert paths

Activate
Enable workflow after testing

How To Customize Nodes

Webhook Node** → Change endpoint path or add authentication
Validation Node** → Add more fields like plan or email
Calculation Node** → Modify threshold logic
Switch Node** → Adjust percentage ranges
Slack Node** → Customize message format and channel
Jira Node** → Update ticket structure
Gmail Node** → Modify email subject, HTML, recipients

Add-ons & Enhancements

Add deduplication to avoid repeated alerts
Store usage data in database or Google Sheets
Send alerts to multiple email recipients
Integrate with CRM or billing systems
Add cooldown or rate limiting
Enrich partner data using external APIs

Use Case Examples

Monitor API usage for partners in SaaS platforms
Prevent service downtime due to overuse
Trigger internal review processes automatically
Automate partner upgrade discussions
Improve operational visibility for teams

This workflow can be adapted for many other automation use cases as well.

Troubleshooting Guide

| Issue | Possible Cause | Solution |
| ----------------------- | -------------------------------- | ----------------------------------- |
| Workflow not triggering | Webhook not called | Verify webhook URL and method |
| Invalid payload error | Missing fields | Ensure required fields are included |
| Slack message not sent | Incorrect channel or credentials | Reconfigure Slack node |
| Jira ticket not created | Wrong project or API issue | Verify Jira credentials |
| Email not sent | Gmail OAuth issue | Reconnect Gmail account |
| Incorrect usage % | Invalid data format | Ensure numeric values |
