When calling the flexible audiences endpoint defined in
“Custom Audiences | Docs | Twitter Developer Platform”

The post request returns an error
“invalid json string”

The json string is:

[  
  {  
    "operation_type":"Create",
    "params":{  
      "name":"my_flexible_audience_name",
      "audience_type":"FLEXIBLE",
      "segments":{  
        "boolean_operator":"AND",
        "child_segments":[  
          {  
            "custom_audience_id":"TYIF",
            "frequency":1,
            "frequency_comparator":"NUM_GT",
            "lookback_window":30,
            "negate":true,
            "child_segments":[  

            ]
          },
          {  
            "boolean_operator":"OR",
            "child_segments":[  
              {  
                "custom_audience_id":"TXR1",
                "lookback_window":30,
                "child_segments":[  

                ]
              },
              {  
                "custom_audience_id":"TYFO",
                "frequency":1,
                "frequency_comparator":"NUM_GT",
                "lookback_window":30,
                "negate":true,
                "child_segments":[  

                ]
              }
            ]
          }
        ]
      }
    }
  }
]

This is defined in postman.

This is how I am calling it in python:

    resource = '/' + '10' + '/batch/accounts/{account_id}/custom_audiences'.format(account_id=account_id)
    headers = {'Content-type': 'application/json'}
    params = request.get_json
    response = Request(client, 'post', resource, headers=headers, params=params).perform()

The error returned is :
<BadRequest object at 0x109055520 code=400 details=[{‘code’: ‘INVALID’, ‘message’: ‘The JSON string format is invalid’}]>

Hey @_mshariff

Interesting, have you tried changing this line:
response = Request(client, 'post', resource, headers=headers, params=params).perform()
to something like
response = Request(client, 'post', resource, headers=headers, body=params).perform() ?

Thanks!

Hi @imit8me,

Hi @imit8me
Any idea on where the issue with this could be.
