Add easy cache to your endpoint with Metatools

• 2 min read

In today’s tech ecosystem, APIs play a pivotal role in connecting services. Tools like Zapier, Make, and Retool Workflows have revolutionized how we integrate functionality, often without writing a single line of code.

These platforms, known for their simplicity, enable you to create and deploy API endpoints or webhooks quickly.

However, convenience comes at a cost.

The Limitations of No-Code/Low-Code Webhooks #

While these solutions simplify integration:

  • Request-Based Billing: Many charge per API call, making frequent requests costly.
  • Latency Issues: Public endpoints, especially on platforms like Retool Workflows, may exhibit slow response times due to infrequent updates.
  • Frontend Compatibility: Directly calling such APIs from browsers often results in CORS (Cross-Origin Resource Sharing) errors.

Solving the Challenges with Proxy and Cache #

Here’s where tools like Proxy MetaTools shine. Acting as an intermediary, proxies can enhance the efficiency and accessibility of your APIs in several ways:

Proxy Functionality #

  • CORS Handling: A proxy resolves CORS issues by sitting between the frontend and the target API. Instead of dealing with complex configurations, you can route calls through the proxy.
  • Enhanced Security: Sensitive endpoints can be hidden behind the proxy, reducing exposure.

API Caching #

Frequent API calls? Set up a cache with Proxy MetaTools to reduce redundant requests and improve response times:

  • Optimized Billing: Platforms like MetaTools only charge when the cache is refreshed, unlike others that bill per request.
  • Latency Reduction: Cached data ensures that most requests are served instantly, especially useful for APIs with infrequent updates.

Example: Integrating with Retool Workflows #

Suppose you’re using Retool Workflows to trigger processes. By leveraging Proxy MetaTools:

  1. Configure the proxy for CORS-friendly access from your frontend.
  2. Add a cache layer to limit repetitive calls, ensuring cost efficiency and improved performance.

Why Proxies and Caches Matter #

Proxies and caches are more than just tools; they’re enablers. They allow you to scale applications, reduce costs, and overcome technical limitations imposed by third-party platforms.
