Want to create Campaign from Creator

I want to create a campaign in Zoho Campaign from Zoho Creator. I wrote a function in the creator but I am getting an error.

Here is my code:

void Create_Campaign()

{

response = getUrl(" https://campaigns.zoho.com/api/getmailinglists?authtoken=f4e70b7d0e52c18f22622f0e57ba30d8&scope=CampaignsAPI&resfmt=JSON");

list_of_details = response.get("list_of_details");

for each elmnt in list_of_details

{

listkey = elmnt.get("listkey");

}

create_campaign = getUrl(" https://campaigns.zoho.com/api/v2/createCampaign?campaignname=CampaignFromCreator&from_email=kaioumcse12@gmail.com&subject=CampaignFromCreator& authtoken=f4e70b7d0e52c18f22622f0e57ba30d8&resfmt=json&content_url= https://app.zohocreator.com/arfaterrahman25/mounna/#Page:Campaign_Page&list_details=" + input.listkey );

info create_campaign ;

}

The error is:

{"message":"Unable to find the resource you're looking for.Please recheck the documentation and try again.","version":"1","URI":"/api/v2/createCampaign","Code":"1004","status":"error"}

The 1004 error means: Wrong URL entered.

I have used a Zoho Creator's URL which is a Page type in Creator.

I have a few questions regarding this post.
1. While creating a new campaign in Zoho Camapgin your documentation used POST method but when I used POST method, I got an error. In live chat support, they said to use GET method but now I get another error.

2. Is Zoho Creator "PAGE" type acceptable as "content_url"?

If yes or not, can you please suggest what kind of "HTML URL" content is acceptable as "content_url"?
