Ionic and wordpress Rest Api in Plugin WP Job Manager

Hi! Thanks for the answer. Indeed, I’m learning and using multiple tutorials about integration between ionic and wp api. The WP Rest api works fine, but I don’t know how to call the elements from the content. I mean, with the tutorial the posts works fine, but I don’t want the post section, I want the job listings (in my app they will be business listings). I’m trying to learn about business finder /near to me listings to show all the business and restaurants in my town. But I don’t know how. There is a tutorial about calling wordpress pages but I have the same issue, I’m new in this and I don’t know how to call all the contents ( business title, link, featured image, etc.).
