integration with Notion

Hi.
I'm tryng to use zapier for syncing notes between Zoho and my Notion Database.
But when creating a zap with their models, I get an error wih this kind of message :

Step 1 - New Note Card in Notebook in Zoho Notebook

request to https://notebook.zoho./%7B%7Bsel_dc%7D%7D/api/v1/notification/filtered/register?JSONString=%7B%22resource_type%22%3A%22NOTEBOOK%22%2C%22filter_type%22%3A%22ID%22%2C%22filter_value%22%3A%22lovap7e4ebb0fdbaf4ac697d9218619d32fbf%22%2C%22action%22%3A%22UPDATE%22%2C%22url%22%3A%22https%3A%2F%2Fzapier.com%2Fhooks%2Fstandard%2F19820952%2Fcf840faec6aa42c5acdf1f5775131ec6%2F%22%7D failed, reason: getaddrinfo ENOTFOUND notebook.zoho.

I've already opened a ticket on Zapier side, but as I use free version of Zoho, they say it's probably due to a limitation in free version of your solution.
Do you know if there is any differences on API usage between free and paid version of Zoho Notebook ?

Thanks for your help
