MMS Not Working

Can you try one of the programming language codes from the link below?

Sorry but for my app it has to be done with cURL

What I was asking you to do was for double checking to see if your account, number and content are correct and works well. If it works with the code then we know the way you call cCurl is the problem.

I have the same problem, but i use python.

My SMS app works perfectly, but when i try to send a MMS i get the phone number error

Just to clarify a bit more, I have been using the SMS end point with cURL and it works perfectly but the MMS is giving wrong Phone Number error. When I go to the RingCentral API website and test out the MMS end point, I also get the same error, in other words it looks like it is also broken on their site.

Can you both call thing this API and detect if your number support "MmsSender" feature?

Using the RingCentral Python SDK, the code is something like this:

from ringcentral import SDK

RECIPIENT = '<ENTER PHONE NUMBER>'

RINGCENTRAL_CLIENTID = '<ENTER CLIENT ID>'
RINGCENTRAL_CLIENTSECRET = '<ENTER CLIENT SECRET>'
RINGCENTRAL_SERVER = 'https://platform.devtest.ringcentral.com'

RINGCENTRAL_USERNAME = '<YOUR ACCOUNT PHONE NUMBER>'
RINGCENTRAL_PASSWORD = '<YOUR ACCOUNT PASSWORD>'
RINGCENTRAL_EXTENSION = '<YOUR EXTENSION, PROBABLY "101">'

rcsdk = SDK( RINGCENTRAL_CLIENTID, RINGCENTRAL_CLIENTSECRET, RINGCENTRAL_SERVER)
platform = rcsdk.platform()
platform.login(RINGCENTRAL_USERNAME, RINGCENTRAL_EXTENSION, RINGCENTRAL_PASSWORD)

def read_extension_phone_number():
  resp = platform.get("/restapi/v1.0/account/~/extension/~/phone-number")
  jsonObj = resp.json()
  for record in jsonObj.records:
    for feature in record.features:
      print (feature)

read_extension_phone_number()

Unfortunately I cannot test it with Python, however if you go to the RingCentral API website:

https://developers.ringcentral.com/api-reference/SMS/createMMS
If you test that end point out, it will work without an attachment, it will run perfectly. However if you add an attachment to the MMS it gives you a phone number error.

That is why I asked you to check if your number support MMS.

You can cCURL to send a message. You CANNOT cCURL to get your number info?
