Automate Your Pokémon Data Fetching with Rate Limiting
detail.loadingPreview
This n8n workflow automates fetching Pokémon data from Airtable, intelligently managing API calls with Redis-powered rate limiting. It ensures efficient data retrieval while preventing API abuse.
About This Workflow
This n8n workflow is designed to streamline the process of retrieving Pokémon data from an Airtable base. It leverages webhooks to trigger the workflow, capturing incoming API keys and initiating a robust rate-limiting mechanism. Using Redis, the workflow tracks API usage on a per-minute and per-hour basis, ensuring that predefined limits (10 calls per minute and 60 per hour) are not exceeded. If limits are hit, a 'You exceeded your limit' message is triggered. Successful data fetches from Airtable are processed, extracting Pokémon names and URLs, and formatted into a user-friendly response. This solution is ideal for applications or services that require dynamic Pokémon data without overwhelming external APIs.
Key Features
- Automated Data Fetching: Seamlessly pulls Pokémon data from an Airtable base.
- Intelligent Rate Limiting: Employs Redis to enforce per-minute and per-hour API call limits.
- Webhook Integration: Trigger workflows dynamically using incoming API requests.
- Customizable API Key Handling: Generates unique keys for granular tracking.
- Efficient Data Transformation: Extracts and formats relevant Pokémon information.
How To Use
- Configure Webhook: Set up the
Webhook1node to receive incoming requests and set your authentication method (e.g.,headerAuthwithx-api-key). - Set API Key: Use the
Setnode to extract and format thex-api-keyfrom the webhook headers, combining it with the current hour and minute for unique identification. - Per-Minute Rate Limiting: Connect the
Setnode to theRedisnode to increment a counter for the generated API key. Configure thePer minutenode to check if the count is less than or equal to 10. - Per-Hour Rate Limiting: If the per-minute limit is met, use the
Set2node to generate a slightly different key (including just the hour) and connect it toRedis1for hourly counting. Configure thePer hournode to check if the count is less than or equal to 60. - Handle Exceeded Limits: If either rate limit is exceeded, the workflow directs to
Set1orSet3to set an error message. - Fetch Pokémon Data: If rate limits are not exceeded, the
Per hournode (orPer minuteif directly connected) triggers theAirtablenode to list Pokémon data. - Process and Respond: The
Functionnode processes the Airtable data, extracts Pokémon names and URLs, and constructs a JSON response. TheSet1andSet3nodes are also connected to the limit-exceeded paths to provide feedback.
