I am creating a dialer to call patient's.
Once they answer it will ask them:
say: This is {our company name} calling to schedule an appointment. If this is {{INSERT FIRST & LAST NAME }} and you are available to scheduling your appointment please press 1
2 questions: 1) How can I pass the name to Twilio via REST API, I see I can pass the number easily to dial but how can I send the number and the name to say? 2) How do I insert the name into the studio flow? to use TTS to say their name in between generic audio?
In addition to the mandatory parameters to and from you'll need to pass a third parameter named parameters which should be a JSON data as a string (key value pairs).
In your case, if you'd like to pass the full name as "Smith, John" then parameters={"full_name": "Smith, John"}.
With this, a widget in your Flow can reference the variable {{flow.data.full_name}}.
You can have more key/value pairs like: parameters={"first_name": "John", "last_name": "Smith"} and reference them as {{flow.data.first_name}} and {{flow.data.last_name}}.
You did not say in your question what language and library you use but if you use Twilio's Node.js library here is a link to Twilio's docs about this: (https://www.twilio.com/docs/studio/rest-api/execution?code-sample=code-create-an-execution-with-custom-parameters&code-language=Node.js&code-sdk-version=3.x)
