Types

type Call 

type Call struct {
	ID          string
	Status      CallStatus
	Source      string
	Destination string
	NumberID    string
	CreatedAt   time.Time
	UpdatedAt   time.Time
	EndedAt     *time.Time
}

A Call describes a voice call which is made to a number.

A call has legs which are incoming or outgoing voice connections. An incoming leg is created when somebody calls a number. Outgoing legs are created when a call is transferred.

func CallByID 

func CallByID(client *messagebird.Client, id string) (*Call, error)

CallByID fetches a call by it's ID.

An error is returned if no such call flow exists or is accessible.

func InitiateCall 

func InitiateCall(client *messagebird.Client, source, destination string, callflow CallFlow, webhook *Webhook) (*Call, error)

InitiateCall initiates an outbound call.

When placing a call, you pass the source (the caller ID), the destination (the number/address that will be called), and the callFlow (the call flow to execute when the call is answered).

func (*Call) Delete 

func (call *Call) Delete(client *messagebird.Client) error

Delete deletes the Call.

If the call is in progress, it hangs up all legs.

func (*Call) Legs 

func (call *Call) Legs(client *messagebird.Client) *Paginator

Legs returns a paginator over all Legs associated with a call.

func (Call) MarshalJSON 

func (call Call) MarshalJSON() ([]byte, error)

MarshalJSON implements the json.Marshaler interface.

func (*Call) UnmarshalJSON 

func (call *Call) UnmarshalJSON(data []byte) error

type CallFlow 

type CallFlow struct {
	ID    string
	Title string

	// Each object in the steps array in a call flow describes an operation
	// that executes during a call, e.g. transferring a call or playing back an
	// audio file.
	Steps []CallFlowStep

	// Record instructs the Voice system to record the entire call.
	//
	// Note that this is distinct from the Record CallFlow step which records
	// only a single message from the callee.
	Record bool

	CreatedAt time.Time
	UpdatedAt time.Time
}

A CallFlow describes the flow of operations (steps) to be executed when handling an incoming call.

Example 
callflow := CallFlow{
	Title: "My CallFlow",

			Payload:  "Hello",
			Voice:    "male",
			Language: "en-US",
		},
		&CallFlowPauseStep{
			Length: time.Second * 4,
		},
		&CallFlowTransferStep{
			Destination: "31600000000",
		},
	},
}
_ = callflow

Output:
