Pretty much title says all, I was able to get the snippet within test = {} to work within salesforce workbench. Would love some guidance on what I am doing wrong as individual "non-bulk" requests work.

test = {
   "allOrNone" : "false",
   "records" : [{
       "attributes" : {"type" : "Sensor_Reading__e"},
       "id__c": "679",
       "power__c": "15.00",
       "temperature__c": "72.6",
       "captureTime__c": "2019-05-20"

headers = {
    'Content-Type': 'application/json',
    'Accept': 'application/json',
    'Authorization': 'Bearer '+str(response.json()['access_token'])
response = requests.post('https://na50.my.salesforce.com/services/data/v45.0/composite/sobjects', headers=headers,data=test)



[{"message":"Unexpected character ('r' (code 114)): expected a valid value (number, String, array, object, 'true', 'false' or 'null') at [line:1, column:2]","errorCode":"JSON_PARSER_ERROR"}]

enter image description here

  • Could you please post your Python and error message inline, using the {} tool to format your code, rather than posting a screenshot?

  • Please include code and error messages as text rather than images. The former is searchable and accessible on screen readers, among other things, while the latter is not, making it much more exclusionary.

You need to convert the object via dumps. As near as I can tell:

import json


payload = json.dumps(test)
response = requests.post('https://na50.my.salesforce.com/services/data/v45.0/composite/sobjects', headers=headers,data=payload)

Check out the JSON library for more details.

  • I swear to god that did not work for me and now it does, go figure lol. Thanks!
