Hi I am new to Ignition and trying to learn quickly. I am currently trying to figure out the formatting needed to post API calls with rest via script. Currently I am getting an error when I execute the script and I can’t quite figure out what I have incorrect. Below is my script being used. Followed by the error I am receiving. Any ideas on what I have incorrect? ```auto import pprint pp = pprint.PrettyPrinter(indent=4) headers = { #Request headers 'Content-Type': 'application/json', 'Ocp-Apim-Subscription-Key': 'MYSubscriptionKEY', } body = { "resourceGroup": "Tugger", "location": "B05", "description": "Test with Python", "requestType": "Pull", "itemNo": "18308-TGZ-A030-21", "containerCount": 1 } #Get the json response from Cella url = "https://api.cella-tech.com/RequestManagement/v1/ResourceGroup/Request", body, headers CellaResponse = system.net.httpPost(url) CellaJSON = system.util.jsonDecode(CellaResponse) #print to see the response print pp.pprint(CellaJSON) ``` ```auto Traceback (most recent call last): File "input", line 21, in module IOError: no protocol: ('https://api.cella-tech.com/RequestManagement/v1/ResourceGroup/Request', {'resourceGroup': 'Tugger', 'requestType': 'Pull', 'description': 'Test with Python', 'itemNo': '18308-TGZ-A030-21', 'location': 'B05', 'containerCount': 1}, {'Ocp-Apim-Subscription-Key': 'MYSubscriptionKEY', 'Content-Type': 'application/json'}) ``` ---

Can you fix your post so that the code is posted with proper formatting? Either enclose it in triple backticks or use the preformatted text editor control. ---

Hey @Kevin.Herron I have updated this now. ---

> [@Luke\_Abraams](#): > > `url = "https://api.cella-tech.com/RequestManagement/v1/ResourceGroup/Request", body, headers` I'm not sure what you think this line is doing, but it's probably not what you think. This turns the `url` variable into a tuple, which is not the argument expected by `httpPost`. ---

Yea I have updated since then. Still getting a 400 error, I was just getting python down a little so the changes with the jython are getting me. Below is my current that I get a 400 return response. Below that is my python that works correctly though. I am not sure what is sending differently that it doesn’t like the post. ```auto import pprint pp = pprint.PrettyPrinter(indent=4) headerValues = { # Request headers 'Content-Type': 'application/json', 'Ocp-Apim-Subscription-Key': 'MySubscriptionKey', } postData = "{'resourceGroup': 'Tugger','location': 'B05','description': 'Test with Python','requestType': 'Pull','itemNo': '18308-TGZ-A030-21','containerCount': 1 }" # get the json response from Cella url = "https://api.cella-tech.com/RequestManagement/v1/ResourceGroup/Request" #CellaResponse = system.net.httpPost(url, "application/json", postData, 10000, 60000, "", "", headerValues) CellaResponse = system.net.httpPost(url, "application/json", postData, 10000, 60000, "", "", headerValues, "false") CellaJSON = system.util.jsonDecode(CellaResponse) #print to see the response print pp.pprint(CellaJSON) ``` ```auto import http.client import json connection = http.client.HTTPSConnection('api.cella-tech.com', 443, timeout=30) headers = {'Content-type': 'application/json','Cache-Control': 'no-cache','Ocp-Apim-Subscription-Key': 'MySubscriptionKey'} data = { "resourceGroup": "Tugger", "location": "B05", "description": "Test with Python", "requestType": "Pull", "itemNo": "18308-TGZ-A030-21", "containerCount": 1 } json_data = json.dumps(data) connection.request('POST', '/RequestManagement/v1/ResourceGroup/Request', json_data, headers) response = connection.getresponse() print(response.read().decode()) ``` ---

You can put all this into a dictionary like you had before and then use `system.util.jsonEncode` to encode it as JSON. ---

> [@Kevin.Herron](#): > > system.util.jsonEncode Thank you for the suggestion, sorry if I sound ignorant on this. Is the below how that would be done properly? ```auto Data = "{'resourceGroup': 'Tugger','location': 'B05','description': 'Test with Python','requestType': 'Pull','itemNo': '18308-TGZ-A030-21','containerCount': 1 }" postData = system.util.jsonEncode(Data) ``` ---

No, it would be like the body in your first post. ```auto data = { "resourceGroup": "Tugger", "location": "B05", "description": "Test with Python", "requestType": "Pull", "itemNo": "18308-TGZ-A030-21", "containerCount": 1 } postData = system.util.jsonEncode(data) ``` ---

@Kevin.Herron Thank you! I think that was it, it posted successfully! I am sure I will have more questions along the way but this was huge for me. Thanks for pointing me the right way. ---

You don’t specify your Ignition version, but most of 8.X and all of 8.1.X can use `system.net.httpClient`, which will take care of JSON encoding (of your outbound data) and decoding (of the inbound data) for you, e.g: ```auto client = system.net.httpClient() headers = { 'Content-type': 'application/json', 'Cache-Control': 'no-cache', 'Ocp-Apim-Subscription-Key': 'MySubscriptionKey' } data = { "resourceGroup": "Tugger", "location": "B05", "description": "Test with Python", "requestType": "Pull", "itemNo": "18308-TGZ-A030-21", "containerCount": 1 } response = client.post('api.cella-tech.com' + '/RequestManagement/v1/ResourceGroup/Request', headers=headers, data=data) if response.good: print response.json ``` ---

Thanks @paul-griffith I will keep that in mind. So far I have downloaded the current version which looks like 8.1.15. Once I am able to make/run some POC’s I will move on from running it on my laptop in demo mode. I will definitely keep this in mind during my testing. I was able to use your script above but had to add https:// to the start of the url or it gave an error of no protocol.
