Hi everyone,
I’m building a Power Automate flow that integrates Microsoft Bookings with Zoho CRM. The goal is to automatically create a meeting (event) in Zoho CRM whenever a new appointment is booked via Microsoft Bookings.
To achieve this, I created a Custom Connector in Power Automate:
Base URL: /crm/v2
Endpoint: /Events
Method: POST
Scope: ZohoCRM.modules.ALL
In the connector’s test tab, I enabled Raw Body and used the following payload:
{
"data": [
{
"Subject": "Consultation
with John Doe",
"Start_DateTime":
"2025-08-12T10:00:00+02:00",
"End_DateTime":
"2025-08-12T10:30:00+02:00",
"Description": "Booked via
Microsoft Bookings"
}
]
}
However,
when I test the operation, I receive a 400 INVALID_REQUEST error from Zoho CRM
with the message: "unable to process your request. please verify whether
you have entered proper method name, parameter and parameter values."
The Headers
of the error message is:
{
"cache-control":
"private,no-cache,no-store,max-age=0,must-revalidate",
"content-length": "192",
"content-type":

"80ed74fa-8f44-4a36-9520-c03e719ed98a",
"x-xss-protection": "0;
mode=block"
}
The Body of
the error message is:
{
"code":
"INVALID_REQUEST",
"details": {},
"message": "unable to process
your request. please verify whether you have entered proper method name,
parameter and parameter values.",
"status": "error"
}
I’ve
confirmed the endpoint is /crm/v2/Events, the headers are correct
(Content-Type: application/json, Accept: application/json), and authentication
is successful.
What could be causing this error, and how can I resolve it?
Thanks a lot to anyone who can help!
Best,
Martin

Exporting Charts from ZohoCRM
Hi...I'm relatively new to ZohoCRM, but very happy with it so far. I have all my leads and potentials accurately entered, and like the reports that I can view, with charts at the top of the data.
