Automate API Rate Limit Alerts via Slack, Gmail & Sheets

Effortlessly Monitor API Rate Limits with Real-Time Alerts via Slack, Gmail, & Sheets

Stay ahead of your API usage with our comprehensive automation workflow that monitors API rate-limits on a recurring schedule. Receive instant alerts through Slack and Gmail when usage thresholds are breached, ensuring your operations remain smooth and uninterrupted. Seamlessly log every check to Google Sheets for effective tracking and analysis, giving you peace of mind knowing your API interactions are under control.

What this workflow does

• Runs on a scheduled trigger to periodically check your API's rate-limit status via HTTP request with a bearer token for authentication.
• Parses the response to standardize rate-limit data and calculates the used and remaining quota, usage percentage, and reset time.
• Determines the severity level (Normal, Warning, High, Critical) and flags if the usage percent exceeds the alert threshold.
• Sends critical or warning messages to your designated Slack channel based on the severity level when thresholds are breached.
• Dispatches alerts via Gmail to the on-call recipient, ensuring urgent notifications are never missed.
• Records each data check in a Google Sheets "Log" sheet for ongoing monitoring and decision-making.
