How to perform certain action when a post is created in Strapi CMS?

I am using Strapi CMS for my data handling with a NoSQL database. So, what I am trying to do is to publish the blog on Medium also when I publish it on Strapi CMS.

I have all the credentials for publishing it on medium using API.

So, the question is how to achieve this, how to perform a certain action in Strapi CMS when a post is created or updated, so that I can get the data and send to Medium via POST request.

Answer

So after some research and instruction by Ghosh I came to know about the webhooks provided by Strapi by default.

These hooks are somewhat same as React Lifecycle Hooks

So for my case I have to add a hook which trigger some action after blog post is created. So, in api/blog/models/{blog}.js, I added this code

"use strict";
const fetch = require("node-fetch");

module.exports = {
  lifecycles: {
    async afterCreate(data) {
      const body = {
        title: data.title,
        contentFormat: "markdown",
        content: data.blog_data,
        tags: [],
      };
      const response = await fetch(
        `https://api.medium.com/v1/users/${process.env.CLIENT_SECRET}/posts?accessToken=${process.env.ACCESS_TOKEN}`,
        {
          method: "POST",
          headers: { "Content-Type": "application/json" },
          body: JSON.stringify(body),
        }
      );
    },
  },
};
