Create a file in the folder /middlewares called flatten-api-response.js

function flattenArray(obj) {
  return obj.map(e => flatten(e));
}

function flattenData(obj) {
  return flatten(obj.data);
}

function flattenAttrs(obj) {
  let attrs = {};
  for (var key in obj.attributes) {
    attrs[key] = flatten(obj.attributes[key]);
  }
  return {
    id: obj.id,
    ...attrs
  };
}

function flatten(obj) {
  if(Array.isArray(obj)) {
    return flattenArray(obj);
  }
  if(obj && obj.data) {
    return flattenData(obj);
  }
  if(obj && obj.attributes) {
    return flattenAttrs(obj);
  }
  for (var k in obj) {
    if(typeof obj[k] == "object") {
      obj[k] = flatten(obj[k]);
    }
  }
  return obj;
}

async function respond(ctx, next) {
  await next();
  if (!ctx.url.startsWith('/api')) {
    return;
  }
}

module.exports = () => respond;

Then open up /config/middlewares.js and paste this in at the end.

  {
    resolve:'middlewares/flatten-api-response.js'
  }

If you don’t want to do all of that then look at Transformer | Strapi Market which will do this for you!

@Wasi Did you solve it with the solution above? I created the middleware folder and then pasted the code into /config/middlewares.js but it didn’t work, I keep getting createdAt, updatedAt in the responses

Hey @guilheermeff if you want top remove that data you can customize the controller or services by using entity services from strapi

/**
 * contact-us service
 */

module.exports = {
    getContactUsData: async () => {
      try {
  
        const entries = await strapi.entityService.findMany(
          "api::contact-us.contact-us",
          {
            fields: ['id'],
            populate: {
              hero: {
                fields: ['title'],
                populate: {
                    image: {
                        fields: ['url', 'alternativeText','width', 'height'],
                    }
                }
              },
              contact: {
                fields: ['title', 'description'],
                populate:  {
                    form: {
                        fields: ['*'],
                    },
                    button: {
                        fields: ['title', 'href', 'target'],
                    },
                }
              },
              address: {
                fields: ['address', 'email', 'phone']
              }
            }
          }
        );
  
        return entries;
      } catch (err) {
        return err;
      }
    },
  };

By this you can customize the filed sand you can specify the fields you want. Hop[e this helps
