The API of PicSee allows engineers to shorten URLs using a "programmatic" approach. For example, 91APP's merchants can provide users with a "Create Link" option in the backend to obtain a bmai.app short URL generated by PicSee. To achieve this, their engineers need to integrate and develop the solution.
APIs can also be developed on your own website. For instance, if you want to share a "Google Form" but don't want to use long and unsightly URLs, you can obtain the Google Form URL and convert it into a short URL (as shown below). Or, like modern automobile companies do after servicing, they automatically send a short URL with a personalized satisfaction survey.
