I am using the following import in my code:
from google.ads.googleads.v20.common.types.asset_types import (
LeadFormCustomQuestionField, LeadFormSingleChoiceAnswers, )
And here's the logic I'm using to add custom questions to a lead form:
for question in form_config.get("custom_questions", []):
try:
# Create the question object
custom_question = client.get_type("LeadFormCustomQuestionField")
custom_question.question_text = question["question_text"]
if question.get("field_type") == "MULTIPLE_CHOICE":
# Create SingleChoiceAnswers
sc_answers = client.get_type("LeadFormSingleChoiceAnswers")
sc_answers.answers.extend(question.get("answer_options", []))
# Attach to the question object
custom_question.single_choice_answers.CopyFrom(sc_answers)
# Append the question to the lead form
lead_form.custom_question_fields.append(custom_question)
except Exception as e:
logging.warning(f"⚠️ Skipping custom question due to error: {e}")
However, I am getting the following error:
WARNING:root:⚠️ Skipping custom question due to error: Unknown field for
LeadFormCustomQuestionField: question_text
It seems like question_text is not a valid field in
LeadFormCustomQuestionField in version v20. Could you please confirm what
field should be used to define the question text? I'm trying to create a
Lead Form Asset using my own API, and I'm currently unable to send custom
questions properly to Google Ads.
Also, the query you provided earlier doesn't return the list of custom
questions either. Please help me resolve this.

Thank You
