Success Stories

Our custom API solutions have empowered organizations to unlock 360-degree customer views, eliminate silos, and accelerate lead-to-conversion cycles.

Amazon Vendor Central Reporter

We used the Reports API of the Seller Central API (SP-API) to extract the required information. The extracted data was then cleaned and modified to meet the client’s needs to generate useful reports. Amazon provides the reports in the GZIP format which are converted to CSV before emailing them to the clients.

Shopify Automation (Loveyprints.com)

In this project, Data Prism created an end-to-end automation process for Lovey Prints. Our application automatically retrieved images from any new orders received on loveyprints.com in real-time (using Shopify API). It then assigned the orders to the available artists via shared Google Drive (using Google Drive API).

Instagram-Facebook API Integration (Freestak.com)

Freestak, a marketplace for endurance influencers, wanted to integrate key insights coming from marketing campaigns with their associated influencers. Freestak required obtaining post data and engagement metrics of posts, stories and reels of Instagram influencers.

Food Ordering Scraper (DoorDash, UberEats, Grubhub)

Our client needed merchant-side data of orders coming to restaurants through 3 major ordering companies (DoorDash, Uber Eats, and Grubhub). We were required to implement a smart algorithm to retrieve such a huge volume of information and prevent blocking, duplication, and other problems.
