If you want to integrate your software with the U.S. Postal Service, you can do so with the Postal Service API. This service lets you get information about the delivery status of your packages from the Postal Service. However, this service can present some challenges when it comes to development. In order to overcome this, you can make use of Cross-Origin Resource Sharing (CORS). This mechanism enables web applications to access resources of different origins without having to rewrite their code.
The US Postal Service API contains a security hole. An unnamed researcher reported this vulnerability to the USPS over a year ago. The vulnerability relates to the Informed Visibility tracking service, which allows people to access the addresses and other information of others. While this may not be a significant threat to your business, it is still a security concern. Luckily, there are some ways to use the API in an efficient manner.
USPS is one carrier among many, but you may want to use another carrier. You can buy an API that supports other carriers as well, but you'll pay a higher price in the short term. With ShipEngine, you'll have access to more than 30 carriers. And, if you change your mind about which carrier works best, you can always change carriers. You'll never be stuck with one carrier again. There are many benefits to using a shipping API, and you can choose whichever one best suits your needs.
