How to Scrape All posts of hashtag in instagram

Question

I want to Scrape All the Post Containing some #hashtag from Instagram

I tried it from : https://www.instagram.com/explore/tags/perfume/?__a=1

But It's only giving some posts not every post.

Answer 1

Look carefully at the json you receive.

Navigate to graphql -> hashtag -> edge_hashtag_to_media -> page_info -> end_cursor

That's the identifier you have to use to specify the next batch of medias, like this:

https://www.instagram.com/explore/tags/perfume/?__a=1&max_id=QVFDNWJDZnpGbElpdEV5Q19aaldYWUsxZnc1YUd0Z21yNUZsOWw4V2NxX05ZWnZjT2pRb3lrY29ocDJnM0VNallUWGZVeDIxVURnUzltdHpBR1A1a0VRNw==

You can iterate this process to get more medias for requested hashtag.

A naive example with requests (python3) to extract first 10 batches.

import requests
import json
from time import sleep

max_id = ''

base_url = "https://www.instagram.com/explore/tags/perfume/?__a=1"
for i in range(0, 10):
    sleep(2) # Be polite.

    if max_id:
        url = base_url + f"&max_id={max_id}"
    else:
        url = base_url

    print(f"Requesting {url}")
    response = requests.get(url)
    response = json.loads(response.text)
    try:
        max_id = response['graphql']['hashtag']['edge_hashtag_to_media']['page_info']['end_cursor']
        print(f"New cursor is {max_id}")
    except KeyError:
        print("There's no next page!")
        break

As said in comment, be polite. Instagram will block you if you shoot too many requests per second.
