How to create share link using API

I created this document using API https://developer.lucid.co/reference/createorcopyorimportdocument

Unfortunately, https://developer.lucid.co/reference/createdocumentsharelink does not accept API keys. For security purposes, a share link must correspond to an OAuth2 client.

Generating an OAuth2 token can be found here: https://developer.lucid.co/reference/using-oauth-20.  Additionally, an example of a python script that helps get and refresh OAuth2 tokens can be found here: https://github.com/lucidsoftware/sample-lucid-rest-applications/tree/main/audit-logs-ingestor (the audit log specific stuff being irrelevant here)

Thank you ​@Michael B , let me check it!

​@Michael B 
I got access token using authenticate function from 
https://github.com/lucidsoftware/sample-lucid-rest-applications/blob/main/audit-logs-ingestor/oauth2.py
But when I use the token

import requests

url = "https://api.lucid.co/documents/<MY DOC ID>/shares/shareLinks"

payload = {
    "role": "editandshare",
    "linkSecurity": {
        "restrictToAccount": True,
        "allowAnonymous": True
    }
}
headers = {
    "accept": "application/json",
    "Lucid-Api-Version": "1",
    "content-type": "application/json",
    "authorization": "Bearer <MY OAUTH2 ACCESS TOKEN>"
}

response = requests.post(url, json=payload, headers=headers)

print(response.text)

I get

{
  "code": "accountOperationOnly",
  "message": "Only OAuth2 clients can perform this operation on behalf of a user",
  "requestId": "1aabcd2f027b6732"
}

What is the issue?

actually I slightly changed the python code, I use the following scope when I request the code from redirect URL:
"&scope=account.audit.logs+offline_access+lucidchart.document.content.share.link+lucidchart.document.app.picker.share.link"

​@Michael B Thank you, with

"linkSecurity": {
    "restrictToAccount": False,
    "allowAnonymous": False
}

works for me!

Awesome. I’ll get a version of that helper script created that’s more endpoint agnostic (and ask the user which type of token they want).
