Get page id of a confluence page from its public url

How to get a Confluence page_id given a page_url. For Eg:

If this is the Display URL: https://confluence.som.yale.edu/display/SC/Finding+the+Page+ID+of+a+Confluence+Page

I want to get its page_id using Confluence REST API

More details here

Do you use atlassian-python-api?

In that case you can parse your url to get the confluence space (SC) and page title (Finding the Page ID of a Confluence Page) then use confluence.get_page_id(space, title).

from atlassian import Confluence

page_url = "https://confluence.som.yale.edu/display/SC/Finding+the+Page+ID+of+a+Confluence+Page"

confluence = Confluence(
        url='https://confluence.som.yale.edu/',
        username=user,
        password=pwd)
        
space, title = page_url.split("/")[-2:]
title = title.replace("+", " ")

page_id = confluence.get_page_id(space, title)

Note that when your title contains a special character (+ or ü, ä...) your page url will already contain the id like this: https://confluence.som.yale.edu/pages/viewpage.action?pageId=1234567890 so you might want to check for it first.

EDIT: here a version of what your function could look like:

from atlassian import Confluence
import re
import urllib

# regex pattern to match pageId if already in url
page_id_in_url_pattern = re.compile(r"\?pageId=(\d+)")

def get_page_id_from_url(confluence, url):
    page_url = urllib.parse.unquote(url) #unquoting url to deal with special characters like '%'
    space, title = page_url.split("/")[-2:]

    if re.search(page_id_in_url_pattern, title):
        return re.search(page_id_in_url_pattern, title).group(1)
    
    else:
        title = title.replace("+", " ")
        return confluence.get_page_id(space, title)



if __name__ == "__main__":
    from getpass import getpass
    user = input('Login: ')
    pwd = getpass('Password: ')

    page_url = "https://confluence.som.yale.edu/display/SC/Finding+the+Page+ID+of+a+Confluence+Page"

    confluence = Confluence(
            url='https://confluence.som.yale.edu/',
            username=user,
            password=pwd)

    print(get_page_id_from_url(confluence, page_url))
