Overview

When handling API request retries in Xano, make sure your app deals with requests properly to fix temporary errors and boost reliability. Xano, a strong no-code backend platform, gives you built-in tools and custom scripting options to manage retries effectively. Using these features, you can create a dependable system that automatically retries failed requests based on certain conditions, like timeouts or rate limits, and uses exponential backoff strategies. This approach leads to smoother and more resilient API interactions, reducing disruptions and creating a better user experience.

How to handle API request retries in Xano?

Step 1: Create a New API Endpoint

  1. Log in to your Xano account.
  2. Head over to the "API" section in the left sidebar.
  3. Hit the "+ New API" button to whip up a new API endpoint.
  4. Give it a name and click "Create".

Step 2: Configure the API Endpoint

  1. Inside your shiny new API endpoint, click on "Add a Function".
  2. Pick the right function type (like "Fetch from URL").
  3. Set up this function with all the necessary request details (URL, headers, body, etc.).

Step 3: Implement the Retry Logic

  1. Click on "+ Add New Step" to create a conditional step.
  2. Use the "retry" function within this step to lay out the retry logic.
  • Set the condition to check for HTTP status codes that scream failure (like 500, 502, 503).
  • Define how many retries you want and the intervals between them.
    ```json
    {
    "code": "YOUR_API_CALL_FUNCTION",
    "retries": 3,
    "delay": 2000 // 2 seconds delay between retries
    }
    ```

Step 4: Add Error Handling

  1. Add another step to deal with errors if all retry attempts flop.
  2. Set up this step to log the error and/or notify the right folks.
  3. Optional: Add a friendly error message to be sent back to the client.

Step 5: Test the Endpoint

  1. Use the "Test API" feature in Xano to fire off requests to the endpoint.
  2. Make sure your retry logic is on point by watching for multiple attempts when things go south.
  3. Check the logs for retries and error handling to make sure everything's working as it should.

Step 6: Deploy and Monitor

  1. Once you're happy with the retry logic, deploy the endpoint by turning it on.
  2. Keep an eye on the endpoint usage and logs to catch any weird stuff or unexpected failures.
  3. Tweak and adjust the retry parameters as needed based on real-world performance and requirements.
