Hi,

I've been trying out an online service that allows you to send SMS. Unfortunately I am having difficulty understanding their samples and translating them to VFP.

You can view their code samples for various languages here:

https://www.twilio.com/docs/api/rest/sending-messages

This is what their help desk sent to me:

"But I can help you with making a POST call to send SMS from your application.

You would need these:
URL - You already have it
Account Sid
Auth token
From, To and Body / MediaUrl as form parameters

Check if that library does the following:

Ability to set From, To, Body key value pairs in form rather than in the URL as query parameters. Also ensure that the library sets the Content-type to "application/x-www-form-urlencoded". If it doesn't please set the header manually.

Ability to convert Account Sid & Auth token into a Base64 encoded value.

If it doesn't, you may have to use any built-in / 3rd party VFP libraries to convert "Account Sid":"Auth token" combination to a Base64Encoded value.
eg. if Account Sid = AC123434598475 & Auth Token = slak09j4g49j04j
Base64Encode("AC123434598475:slak09j4g49j04j") - Do not forget the ':'
Set this base64 Encoded value in "Authorization" header, but ensure you prefix the value with "Basic "
So the header would look like,

Authorization Basic < Base 64 encoded value >

The header and form parameter, briefed above, is available in JSON example in the following article
https://www.twilio.com/docs/api/rest/sending-messages"

This is the code I was trying:

SET LIBRARY TO vfpconnection.fll ADDITIVE 

*!*	SetConnectTimeout(oAppInfo.ConnectTimeOut) && Default is 10 seconds
*!*	SetResponseTimeout(oAppInfo.ResponseTimeOut) && Default is 10 seconds
SetConnectTimeout(30) && Default is 10 seconds
SetResponseTimeout(30) && Default is 10 seconds

*!*	https://api.twilio.com/2010-04-01/Accounts/ACb832550f3d5e416b54a3ff1c0c7d08b1/Messages.json \
*!*	    -d "Body=Jenny%20please%3F%21%20I%20love%20you%20<3" \
*!*	    -d "To=%2B15558675309" \
*!*	    -d "From=%2B14158141829" \
*!*	    -d "MediaUrl=http://www.example.com/hearts.png" \
*!*	    -u 'ACb832550f3d5e416b54a3ff1c0c7d08b1:{AuthToken}'
    
m.lcURL = "https://api.twilio.com/2010-04-01/Accounts/ACb832550f3d5e416b54a3ff1c0c7d08b1/Messages.json"

LOCAL ARRAY laPost[3,2]
laPost[1,1] = "Body"
laPost[1,2] = "Test Message from Frank via Twilio"
laPost[2,1] = "To" && name
laPost[2,2] = "+18689999999"
laPost[3,1] = "From" && name
laPost[3,2] = "+18688888888"

IF NOT HttpPost(m.lcURL, @laPost, "", "APITrace()")
	MESSAGEBOX("An error occurred sending the SMS: " + m.cTraceData, 16, "Send SMS Via Twilio")
ENDIF

Can anyone help me get this clear in my head?
