Hey - if I want to get data form the following Radix API (in this case the account balances) I get the following error message:

{“code”:400,“message”:“One or more validation errors occurred”,“details”:{“validation\_errors”:[{“path”:“”,“errors”:[“A non-empty request body is required.”]}],“type”:“InvalidRequestError”},“trace\_id”:“00-994592adc1ef158cee927af48dea2cd0-73e5700a464dfe5f-00”}

**this is the request:**

import requests

headers={‘Content-Type’:‘application/json’}

query = {“network\_identifier”: {“network”: “mainnet”}, “account\_identifier”: {“address”: “\<MY\_ADDRESS\>”}}

r = requests.post(‘\<NOT\_ALLOWED\_TO\_POST\_LINK\>’, params=query, headers=headers)

print(r.text)

I’m very new to this topic - maybe someone can help me.

I use Postman and merely populate it as follows (both Header and Body/raw/json)

Alright got it:

import requests  
import json

headers={‘Content-Type’:‘application/json’, ‘X-Radixdlt-target-Gw-Api’:‘1.1.2’}

query = {“network\_identifier”: {“network”: “mainnet”}, “account\_identifier”: {“address”: “”}}

r = requests.post(‘’, headers=headers, data=json.dumps(query))

print(r.json())
