Not able to scrape the all the reviews

I am trying to scrape this website and trying to get the reviews but I am facing an issue,

• The page loads only 50 reviews.

• To load more you have to click "Show More Reviews" and I don't know how to get all the data as there is no page link, also "Show more Reviews" doesn't have a URL to explore, the address remains the same.

  import requests
  from bs4 import BeautifulSoup
  import json
  import pandas as pd
  a = []
  
  url = requests.get(url)
  html = url.text
  soup = BeautifulSoup(html, "html.parser")
  
  table = soup.findAll("div", {"class":"review-comments"})
  #print(table)
  for x in table:
      a.append(x.text)
  df = pd.DataFrame(a)
  df.to_csv("review.csv", sep='\t')
  

Looking at the website, the "Show more reviews" button makes an ajax call and returns the additional info, all you have to do is find it's link and send a get request to it (which I've done with some simple regex):

import requests
import re
from bs4 import BeautifulSoup
headers = {
"user-agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) snap Chromium/74.0.3729.169 Chrome/74.0.3729.169 Safari/537.36"
}
url = "https://www.capterra.com/p/134048/HiMama-Preschool-Child-Care-App/#reviews"
Data = []
#Each page equivalant to 50 comments:
MaximumCommentPages = 3 

with requests.Session() as session:
    info = session.get(url)
    #Get product ID, needed for getting more comments
    productID = re.search(r'"product_id":(\w*)', info.text).group(1)
    #Extract info from main data
    soup = BeautifulSoup(info.content, "html.parser")
    table = soup.findAll("div", {"class":"review-comments"})
    for x in table:
        Data.append(x)
    #Number of pages to get:
    #Get additional data:
    params = {
        "page": "",
        "product_id": productID
    }
    while(MaximumCommentPages > 1): # number 1 because one of them was the main page data which we already extracted!
        MaximumCommentPages -= 1
        params["page"] = str(MaximumCommentPages)
        additionalInfo = session.get("https://www.capterra.com/gdm_reviews", params=params)
        print(additionalInfo.url)
        #print(additionalInfo.text)
        #Extract info for additional info:
        soup = BeautifulSoup(additionalInfo.content, "html.parser")
        table = soup.findAll("div", {"class":"review-comments"})
        for x in table:
            Data.append(x)

#Extract data the old fashioned way:
counter = 1
with open('review.csv', 'w') as f:
    for one in Data:
        f.write(str(counter))
        f.write(one.text)
        f.write('\n')
        counter += 1

Notice how I'm using a session to preserve cookies for the ajax call.

Edit 1: You can reload the webpage multiple times and call the ajax again to get even more data.

Edit 2: Save data using your own method.

Edit 3: Changed some stuff, now gets any number of pages for you, saves to file with good' ol open()
