Unable to change parameter using Rest API

[Anonymous]

Hi, I am facing an issue while trying to change Report parameter values on power bi service using api request call using the syntax provided in the power bi documentation.

The query that I am sending using python is as below 

dest = 'https://api.powerbi.com/v1.0/myorg/groups/' + self.group_id + '/datasets/' + self.dataset_id + '/Default.UpdateParameters'
headers = {'Authorization': 'Bearer ' + self.access_token}
data = {"updateDetails": [{"name": "ScenarioID","newValue": "110"},{"name":"ChildID","newValue":"13"}]}

Param = requests.post(dest, data=data, headers=headers)

Which is giving me below response

{'error': {'code': 'InvalidRequest',
'message': 'Dataset Parameters list is invalid in DatasetID. Reason: Invalid parameter update details',
'target': 'DatasetID'}}

I am unable to understand how to resolve this I have parameters defined as 

Required box ticked.

Type Decimal Number (I have tried it with text type as well)

suggested values: any

Current Value 108

Please help!

Try this:

dest = 'https://api.powerbi.com/v1.0/myorg/groups/' + self.group_id + '/datasets/' + self.dataset_id + '/Default.UpdateParameters'

body= {
"updateDetails": [
{
"name": "DataBase",
"newValue": "myDB"
},
{
"name": "Server",
"newValue": "123.456.789"
}
]
}

header = {'Content-Type': 'application/json'
,'Authorization': f'Bearer {tokenPBI}', 'Accept': 'text/plain'}

requests.post(dest,
data=json.dumps(body),
headers=header
)

It seems quite a trivial problem but I am unable to figure out the solution.

Please help as it is quite important for my client.
