Stripe API Assistant with PHP Expertise

I am urgently in need of an assistant adept at using PHP to seamlessly manage my Postman account. Your primary responsibility will involve handling incoming payments that appear uncaptured via my Stripe account. Upon identifying such transactions, you'll be tasked with sending a HTTP request to the Stripe API with the goal of overcapturing $1500 for my services. Expect to receive the output of this API request in JSON format. Experience with Stripe API and PHP programming language is crucial for the successful delivery of this unique, fast-paced project.
