In this post you'll learn about the updates, improvements and products which we released in Q3 of 2022. 

## API updates this quarter

Transactional Data API improvements

Added functionality to the transactions endpoint to enable query searching with fundingId. [Learn more >](https://docs.fiserv.dev/public/changelog/api-transactional-data-130)

Statements API improvements

New sandbox environment to test the statements APIs, and additional improvement to query parameters to ensure consistency across APIs. [Learn more >](https://docs.fiserv.dev/public/reference/statements-intro)

Disputes API

View, manage and respond to your transaction disputes/chargebacks to effectively defend and manage costs. Try out the new sandbox environment. [Learn more >](https://docs.fiserv.dev/public/reference/disputes-intro)

Checkouts API

Accept payments through checkouts with reduced PCI requirements. Try out the new sandbox environment to start generating checkout pages. [Learn more >](https://docs.fiserv.dev/public/reference/checkout)

 

## Developer Experience Enhancements

Postman collection improvements

Start testing and integrating faster with Fiserv APIs with our enhanced postman collection which contains all the API endpoints you need with pre-loaded examples. Enter your environment details, like your API key, and get started with a couple clicks. [Learn more >](https://docs.fiserv.dev/public/reference/postman-collection)

Enhanced "try it out" feature in documentation

As an added security feature in our payment and checkout APIs, we include a message signature to help prevent middle-people attacks. This enhanced security is great when going into production, but when trying to test it out quickly in sandbox it adds a couple steps. To enhance the developer experience, when using the "Try it out" feature on our developer portal, you will not require a message signature when testing sandbox - this means our examples work super quickly and all you need is a sandbox API key and a few clicks!
