MMSContent error 500


Thanks for ur last time help. I meet a new issue when sending mms. As request mmscontent should be like

{ "type": "image/jpeg", "filename": "image004.jpg", "payload": "/9j/4AAQSkZJRgABAQ..." }

However, I use python create a dict like this

{'type': 'image/png', 'filename': 'Telstra.png' ,'payload': 'iVBORw0KGgoAAAAN...} 

but the http response is error 500 

message":"Technical error : Execution of JS.PayloadSanityChecks failed with error: Javascript runtime error: \"TypeError: Cannot read property \"type\" from undefined.(PayloadSanityChecks.js:80)\" : An error has occurred while processing your request, please refer to API Docs for summary on the issue"

I just wonder if I make a mistake in setting the type.

Hi servicedesk2

Thanks for reaching out, 

Which version of the SDK are you using? 

In the latest version from github (which uses openapi-generator) heres some sample code 

pic = {'type': 'image/png', 'filename': 'test.png', 'payload': base64_image}

send_mms_request = Telstra_Messaging.SendMmsRequest('from number', 'to number', 'subject', 'reply_request', 'notify_url', pic)

Hi Steven
Hi Steven I dont no if you can see the pic. My testing code is as follow: def mms(): fo=open(r"C:\Users\kane8\Desktop\1.jpg") content=base64.b64encode(         kind=filetype.guess(r"C:\Users\kane8\Desktop\1.jpg")         mms={'type':kind.mime,'filename','payload':content}         print(mms)           api_instance = Telstra_Messaging.MessagingApi(Telstra_Messaging.ApiClient(configuration))         send_mms_request = Telstra_Messaging.SendMmsRequest("a","0450910822","a",False,"",mms)   try: api_response = api_instance.send_mms(send_mms_request) pprint(api_response) except ApiException as e: print("Exception when calling MessagingApi->send_mms: %s\n" % e) But the api response is 500 Cannot read property \"type\" from undefined. Could you plz find the mistake for me. Thanks

Hi Steven
Hi Steven Please disregard my previous comments. The issue has been solved. I figure out it's becase pic should not be a dict. It's a list [{pic1},{pic2}]. Anyway, thanks for your help btw i just wonder if the free account is not able to send mms. Cheers

Cannot send MMS using Python API

Hello Telstra people,

I'm attempting to send an MMS using the free developer account. I've already been able to send and receive SMS through the Telstra API. However, I can't get MMS sending to work.

My code is as below. Going by the response header from the Telstra server, it looks like the presented MMS data is not in a form the webpage expects, but I haven't been able to resolve this. Can you tell me what the problem is, please? It looks similar to the other question in this thread from 2 years ago.

Thanks - Andrew

Python script

import Telstra_Messaging
import base64 as base64

api_instance = Telstra_Messaging.AuthenticationApi()

auth_data  = {
'client_id': 'PP5....G3n', # client ID removed from pasted code
'client_secret': 'dYm...l5t', # client secret removed from pasted code
'grant_type': 'client_credentials',}

api_response = api_instance.auth_token(**auth_data)
configuration = Telstra_Messaging.Configuration()
configuration.access_token = api_response.access_token
messaging_api_instance = Telstra_Messaging.MessagingApi(Telstra_Messaging.ApiClient(configuration))

image_path = 'image001_small.jpg'

def get_base64_encoded_image(image_path):
    with open(image_path, "rb") as img_file:
        return base64.b64encode('utf-8')

image_base64 = get_base64_encoded_image(image_path)

MMS_content = {'type':'image/jpg', 'filename':image_path, 'payload':image_base64}

send_mms_request = Telstra_Messaging.SendMmsRequest(

response = messaging_api_instance.send_mms(send_mms_request)
