Error sending an MMSmessage

When I try to send an MMS message I get:

{ "errorCode" : "InvalidParameter", "message" : "Parameter [attachments] value is invalid.", "errors" : [ { "errorCode" : "CMN-101", "message" : "Parameter [attachments] value is invalid.", "parameterName" : "attachments" } ], "parameterName" : "attachments" }

Does anyone know what's wrong? I have the JSON formatted properly and it worked in the sandbox. Now it does not work in production.

Post some code where you created the POST body.

Are you using any RC SDK to send message?

If yes, then please put you code sample.

Also, the mms api reference you will get it here

https://community.ringcentral.com/questions/103211/error-sending-an-mmsmessage.html

Can you please try once from here and see if this is working for you? You can get the correct json request generated here

No SDK just a HTTP request. The format is correct and it worked fine in the sandbox. Is there some kind of MMS permission that has to be added to the sending number?

Since you are not using any SDK, I cannot help providing you with sample code.

But you can call this API to read a user's phone numbers and detect if the number is MMS enabled (under the 'features' array "MmsSender".

You should also double check if you have set the server for production "platform.ringcentral.com", the POST request header and make sure that you read and create the attachments properly in your production environment. Many developers have such problems when they run their app okay in their local machine but fails when deployed and run on their remote server.

The full JSON I am sending is:

{ "to": [{"phoneNumber": "+1xxxxxxxxxx"}], "from": {"phoneNumber": "+1xxxxxxxxxx}"}, "text": "Test SMS", "attachments":["data:image/jpeg;name=overlay.png;base64,iVBORw0KGgoAAAANSUhEUgAAAAYAAAAGCAYAAADgzO9IAAAAEUlEQVR42mNgYGC4iQMPnAQAw/QehVmSyckAAAAASUVORK5CYII="] }

I am sending it to

Accept: application/json

Did you read the phone number features?

Did you also set the content-type header?

header 'content-type: multipart/form-data'

I did not request the read permission when I setup the App so I can't access the endpoint.

When I change the content type to multipart/form-data I get a different error:


{ "message" : "Bad Request", "errors" : [ ] }

What is your app client id?

I added the missing permission to your app so you can now read the phone-number API to detect number features.

It still says:
In order to call this API endpoint, application needs to have [ReadAccounts] permission

Sorry, I forgot to submit the change. Should be ok to call the API in a min.

And also, if I determine that the number does not have MMS access, how would I turn that on?
