I have recently uploaded contact records to HubSpot using Postman. Here is a raw JSON data example and POST method that I use to successfully upload a contact:

“properties”: {

“smbapi”: “yes”,

“email”: “[fcgrinding@junkstermail.com](mailto:fcgrinding@junkstermail.com)”,

“business\_name”:“Forest City Grinding Inc”,

“srvc\_address\_1”:“3544 Stenstrom Rd”,

“srvc\_city\_1”:“”,

“srvc\_state\_1”:“IL”,

“srvc\_zip\_1”:“61109”,

“proposal\_date”:“2021-12-07”,

“proposal\_start\_date”: “2022-01-01”,

“udc\_code\_1”: “COMED”,

“eog”:“electric”,

“fixedprice\_1\_gas\_mcf”: 6.63,

“fixedprice\_2\_gas\_mcf”: 6.11,

“fixedprice\_3\_gas\_mcf”: 5.9,

“term\_1”: 12,

“term\_2”: 24,

“term\_3”: 36,

“smb\_bdm\_name”: “Timothy Chin”,

“smb\_bdm\_phone”: “833-999-9999”,

“smb\_bdm\_email”: “[tim.chin@junkstermail.com](mailto:tim.chin@junkstermail.com)”

}

}

So I tried to automate the process using AWS python Integration for every CSV file that was read into the S3 bucket to create a JSON string to upload into HubSpot. The following output string that failed to upload to HubSpot using the POST method is:

{‘properties’: “{‘smbapi’: ‘yes’, ‘business\_name’: ‘Forest City Grinding Inc’, ‘srvc\_address\_1’: ‘3544 Stenstrom Rd’, ‘srvc\_state\_1’: ‘IL’, ‘srvc\_zip\_1’: ‘61109’, ‘proposal\_date’: ‘2021-12-07’, ‘proposal\_start\_date’: ‘2022-01-01’, ‘udc\_code\_1’: ‘COMED’, ‘fixedprice\_1’: 6.63, ‘fixedprice\_2’: 6.11, ‘fixedprice\_3’: 5.9, ‘term\_2’: 24, ‘term\_3’: 36, ‘smb\_bdm\_name’: ‘Timothy Chin’, ‘smb\_bdm\_phone’: ‘833-999-9999’, ‘smb\_bdm\_email’: ‘tim.chin@junkster.com’}”}

**The error I get is:**

_**Invalid input JSON : Cannot build ObjectSchemaEgg, Invalid input JSON on line 1, column 2: Cannot build ObjectSchemaEgg, some of required attributes are not set [name, labels]**_

@TWilliams2

I am not a python slinging fellow, but if that is the outputted json, I dont think it is valid json

I reformatted to this

```lia-code-sample

 "srvc_address_1": "3544 Stenstrom Rd",
 "srvc_state_1": "IL",

 "proposal_date": "2021-12-07",

 "udc_code_1": "COMED",
 "fixedprice_1": 6.63,
 "fixedprice_2": 6.11,

 "smb_bdm_name": "Timothy Chin",
 "smb_bdm_phone": "833-999-9999",

 }
}

```

@taran42 , any thoughts here? 😀

I agree with @dennisedson on the formatting. Use an online validator/formatter to check errors like that. I like to use [https://jsonformatter.curiousconcept.com/](https://jsonformatter.curiousconcept.com/)

No its not the outputted JSON but rather the input for using the python Post method. The string I used for Postman was almost an exact copy of this except it uses single quotes and everything loads into Hubspot using this raw JSON body nicely everyt ime . However when I try to load this into hubspot using python lambda code I can’t get that to POST to hubspot using Post mathod:

**response = requests.request(“POST”, endpoint\_url+access\_key, headers={‘Content-Type’: ‘application/json’}, data=json.dumps(payload\_data))**  
**token\_response=json.loads(response.text)**

@taran42 and @@dennisedson , the problem was caused by two issues:

- The dictionary should have been placed in json.dump() to convert it to JSON string when doing a POST.
- I was using then wrong endpoint: **[https://api.hubapi.com/crm/v3/schemas/](https://api.hubapi.com/crm/v3/schemas/)** instead of: **[https://api.hubapi.com/crm/v3/objects/contacts/](https://api.hubapi.com/crm/v3/objects/contacts/)**

**Now I just need to find out why the AWS Lambda POSTs allow for duplicate contacts to be created in HubSpot while Postman POSTs prohibit duplicate contacts to be created.**

**Thanks for your help .**

Sorry, I’m not sure what could be going on there.

However, great to hear you got the other problems worked out!
