Fill ACF with Plugin REST API

[xarliebrown]

I'm trying to fill an ACF using the plugin. What I'm doing wrong? Thanks!!

acf_fields = {
'GroupName':{
"customfield": item["field"],

	}

}
post_data = {
"title": item["name"],
"content": item["description"],
"status": "publish",
"acf_data": acf_fields
}

response = requests.post(WORDPRESS_URL, json=post_data, auth=HTTPBasicAuth(USERNAME, APPLICATION_PASSWORD))
