Twilio issues ...

[drgarytraub]

I use Twilio within Alpha extensively. It has worked beautifully for years. I am now finding that certain phone numbers are not working. Has anyone else had problems with this?

[Sarah Mitchell]

What do you mean by "certain phone numbers are not working"? Outbound calls? Inbound calls? SMS?

[mikeallenbrown]

I use Twilio daily in one of my apps (just SMS). I haven't noticed any issues. I log failed messages so I'd know what Twilio is saying is wrong. Do you log (or know) what the reported failure is?

EDIT: If you want to private message me one of the number that are failing I'd be happy to send a test SMS to it.

Hi Sarah,

Sending SMS text messages from my application to a mobile phone number.

Hi Mike,

"I log failed messages so I'd know what Twilio is saying is wrong."

How do I do that? Do I need to go to twilio to see the logs or is there a way to capture the error within alpha when this fails:

flag = twilio_send_sms(pResult,to,message,namedResource)


So, if flag is false, can I capture the twilio error?

[mikeallenbrown]

I send Twilio SMS via CURL in an xbasic module and not through Alpha's documented function twilio_send_sms().

Here is some abbreviated code ...

dim cf_1 as extension::CurlFile
dim flag_1 as l
dim response as p
dim ce as extension::Curl
    ce = extension::Curl.Init()

dim authToken as c = "MY TOKEN"
dim acctSID as c = "MY SID"
dim twilioNumber as c = "SOME PHONE NUMBER"

ce.setOpt("URL","https://api.twilio.com/2010-04-01/Accounts/" + acctSID + "/Messages.json")
ce.setOpt("NOPROGRESS",1)
ce.setOpt("USERPWD",acctSID + ":" + authToken)
ce.setOpt("POSTFIELDS",posted_fields)
ce.setOpt("POSTFIELDSIZE_LARGE", len(posted_fields) )
ce.setOpt("USERAGENT","curl/7.34.0")
ce.setOpt("MAXREDIRS",50)
ce.setOpt("CAINFO",a5.Get_Exe_Path()+"\caroot\ca-cert.pem")
ce.setOpt("CAPATH",a5.Get_Exe_Path()+"\caroot")
'ce.setOpt("SSH_KNOWNHOSTS","C:\Users\Administrator\AppData\Roaming/_ssh/known_hosts")
ce.setOpt("CUSTOMREQUEST","POST")
ce.setOpt("TCP_KEEPALIVE",1)
ce.SetOpt("FILE",cf_1)

flag_1 = ce.Exec()

    if flag_1 then
        'Connected to Twilio successfully

        dim contents as c = ""
            contents = cf_1.GetContent()

        'Parse twilio response
        response = json_parse(contents)

        if response.status = "queued" then
            'SMS message sent successful
            p.msgStatus = response.status
            p.msgSID = response.sid
        else
            'SMS message NOT sent, get the reason from Twilio
            p.msgStatus = "Response Status: " + response.status + crlf() + "Message: " + response.message + crlf() + "Code: " + response.code + crlf() + "More Info: " + response.more_info
        end if

    else
        'There was a problem connecting to the service
    end if

ce.close()​

The only I don't check is if a message gets "Queued" but still fails to send. For that I'd have to either check the Twilio account and match the SID or develop another routine to check these.

Looking over Alpha's documentation for twilio_send_sms() they too are returning Twilio's response. So if you are using this function take a look here: https://documentation.alphasoftware....20function.xml

Hi Mike,

Thanks for your input. Unfortunately, when I run the code, pResult is empty no matter whether flag was true or false.

[mikeallenbrown]

*shrug* ... I don't know. I can still run a "bad" number through mine if you want and see what the result is. Up to you.

[Sarah Mitchell]

If you think this is an issue with Alpha Anywhere, you'll need to send us a test case to [email protected].

[drgarytraub]

Hi Sarah,

Thanks for responding.

I am just wondering if pResult should be returning something from Twilio. I would think it should.

And how would I inspect what's in pResult? I would think something like:

?pResult

but that is returning empty whether twilio send was successful (true) or not (false).

Would I need to do something like:

?pResult. i.e. a dot and then something like errors e.g., ?pResult.errors

Please advise.

Gray: I received your message but couldn't respond for some reason. Alpha forum said I didn't have permission...

Both numbers you gave me were "queued"...this means Twilio received the request and will send the SMS. I have a test component for you. I'll post it here in a few moments.

[mikeallenbrown]

Attached to this post is a Twilio test component. You must provide your own Twilio number, account SID, and auth. token. They get hard coded in the xbasic function. Included in the function is the ability to examine twilio's response.

[Sarah Mitchell]

Gary,

I ran the function in build 8369 and pResult always contains something. Are you using an older build.

[CharlesParker]

I use twilio myself, I am on 8245-5650 and haven't seen any issues. Have you checked the twilio logs? They can also tell you a little bit about what errors are on their end.
