API Integration with Wordpress

We have a Wordpress site that requires a custom plugin that will integrate with a 3rd Party API call with token based authentication. The plugin will need to call the API within the boundaries of the API allowable functions, populate a MySQL database and formulate the results in line with the theme. The plugin will need to differentiate between different animals from the API call. This is for an animal charity site that advertises on a 3rd party platform that would like the information in that 3rd party platform to be available on the Wordpress site natively without having to upload each animal details twice. Please contact me for more information if required. All documentation will be provided for the API.
