“The company was making thousands of retry calls per second. Lunar.dev managed to flip the script for us out-of-the-box”. - VP R&D @Fondue, Omri Mosseri
Fondue was acquired by Postscript - a leading SMS marketing platform for Shopify, making SMS the #1 revenue channel for over 10,000 Shopify brands and growing at pace.

Developing a cashback system is no easy feat. The RnD team at Fondue acquired by Postscript, understands that every call is a revenue line or refund request, tending to each call is business-critical.
Their mission is to enable brands to grow profitably by replacing the coupon code system with CashBack processes. They help ecommerce brands design and operate SMS programs that keep users engaged, drive revenue, power list growth and increase margins with the smart coupon alternative.
Use Case:
Imagine the following scenario: Thousands of retries in seconds (we’re talking over 25K), creating a backlog of retries and failed requests.
This was the case Fondue acquired by Postscript, and the goal was clear: implement an orchestration layer to gain visibility and optimization for API consumption over the massive volumes of third party API traffic generated per second.
In case of a product like this, speed and accuracy are of the essence and every API request impacts performance and revenue—especially when handling transactions like refunds.
The key challenge was:
- How quickly could the team process refunds while managing API rate limits?
- What happens when multiple API requests get queued by the cloud provider?
In a typical setup, excessive retries occur when requests are throttled or delayed. For example, if seven requests were queued on the cloud provider’s side, they would sit in the backlog, waiting for processing. This caused delays and inefficiencies.
How Lunar.dev Reduced API Retries and Optimized API Consumption at Scale
Managing API consumption efficiently is critical for businesses that rely on high volumes of API requests. Lunar.dev provided a game-changing solution that reduced API retries, optimized priority queues, and improved visibility into API traffic—without requiring custom-built middleware.
The Solution: Lunar.dev’s Smart API Consumption Gateway
By integrating Lunar.dev’s pre-built solution, the team reduced retry calls to just one retry per 100,000 requests—a dramatic improvement over conventional retry strategies.
Lunar.dev's priority queue ensured that API requests, which would have otherwise been throttled, were efficiently managed, preventing unnecessary delays.
The Game-Changer: API Aggregation Without Data Retention
The biggest impact came from Lunar.dev’s ability to aggregate thousands of requests efficiently while maintaining optimal perfomance and reliability:
Prioritization—Each call was processed based on business logic, ensuring mission-critical requests weren’t delayed.
Seamless integration—Instead of building and maintaining an in-house middleware solution, the team installed Lunar.dev and gained instant visibility into their API consumption patterns.
No data retention—Lunar.dev never stores or sees the payload.
