XML Verbs

Twilio's Simple XML Instruction Set

This is the real exciting part. When your application responds to Twilio with XML, we treat it like a set of actions to perform. Verbs! Here's what you need to know:

• Root Element: The root document element is always <Response>
• XML Elements: Are case-sensitive (as XML is), and words are capitalized, such as <Response> (not <response>)
• XML Attributes: Are case-sensitive (as XML is), and are "camelCased," beginning with a lower case letter. For example, maxLength instead of maxlength, MaxLength, or MAXLENGTH
• XML Comments: Just like HTML comments, feel free to use them liberally in your XML to help you debug. <!-- COMMENTS HERE -->
• Verbs: Include one or more of the verbs listed below.
• Nesting: Some of the verbs can be nested inside each other. Read below to find out more...

Here are the core five Twilio Verbs...

• <Say>: Say some text to the caller
• <Play>: Play an audio file to the caller
• <Gather>: Gather phone keypad digits and submit them back to my application
• <Dial>: Dial another phone number and connect the current call if someone picks up
• <Record>: Record the caller's voice and submit the recording back to my application
