Get focus keyword through WordPress API for a post

Hey there,

I’m trying to retrieve focus keyword from a draft post using wordpress API.

I manage to get the description, title and content but I don’t knwo why i cannot get the yoast focus Keyword.

Do you have any idea of what I can do ?

here is a sample of the script I’m using :

from wordpress_xmlrpc import Client, WordPressPost
from wordpress_xmlrpc.methods.posts import GetPost

# website connexion
url = ''
username = ''
password = ''

# client
client = Client(url, username, password)

# Article ID
post_id = 12345

# data
post = client.call(GetPost(post_id))
print(post)

# meta
yoast_title = None
yoast_description = None
yoast_keywords = None

for meta_field in post.custom_fields:
    if meta_field.keys == '_yoast_wpseo_title':
        yoast_title = meta_field.value
    elif meta_field.keys == '_yoast_wpseo_metadesc':
        yoast_description = meta_field.value
    elif meta_field.keys == '_yoast_wpseo_focuskw':
        yoast_keywords = meta_field.value

# display
print("Titre Yoast:", yoast_title)
print("Description Yoast:", yoast_description)
print("Mots-clés Yoast:", yoast_keywords)
