*Since Camel 2.20*

// HEADER START
*Both producer and consumer is supported*
// HEADER END

The Twilio component provides access to Version 2010-04-01 of Twilio REST APIs accessible
using https://github.com/twilio/twilio-java[Twilio Java SDK].

Maven users will need to add the following dependency to their pom.xml
for this component:

[source,java]
-------------------------------------------------
    <dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-twilio</artifactId>
        <version>${camel-version}</version>
    </dependency>
-------------------------------------------------


== Twilio Options

// component options: START
The Twilio component supports 8 options, which are listed below.


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *configuration* (advanced) | To use the shared configuration |  | TwilioConfiguration
| *restClient* (advanced) | To use the shared REST client |  | TwilioRestClient
| *username* (security) | The account to use. |  | String
| *password* (security) | Auth token for the account. |  | String
| *accountSid* (security) | The account SID to use. |  | String
| *basicPropertyBinding* (advanced) | Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
| *lazyStartProducer* (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean
| *bridgeErrorHandler* (consumer) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean
|===
// component options: END

// endpoint options: START
The Twilio endpoint is configured using URI syntax:

----
twilio:apiName/methodName
----

with the following path and query parameters:

=== Path Parameters (2 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *apiName* | *Required* What kind of operation to perform |  | TwilioApiName
| *methodName* | *Required* What sub operation to use for the selected operation |  | String
|===


=== Query Parameters (23 parameters):


[width="100%",cols="2,5,^1,2",options="header"]
|===
| Name | Description | Default | Type
| *inBody* (common) | Sets the name of a parameter to be passed in the exchange In Body |  | String
| *bridgeErrorHandler* (consumer) | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | boolean
| *sendEmptyMessageWhenIdle* (consumer) | If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead. | false | boolean
| *exceptionHandler* (consumer) | To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. |  | ExceptionHandler
| *exchangePattern* (consumer) | Sets the exchange pattern when the consumer creates an exchange. |  | ExchangePattern
| *pollStrategy* (consumer) | A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel. |  | PollingConsumerPollStrategy
| *lazyStartProducer* (producer) | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | boolean
| *basicPropertyBinding* (advanced) | Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities | false | boolean
| *synchronous* (advanced) | Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). | false | boolean
| *backoffErrorThreshold* (scheduler) | The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in. |  | int
| *backoffIdleThreshold* (scheduler) | The number of subsequent idle polls that should happen before the backoffMultipler should kick-in. |  | int
| *backoffMultiplier* (scheduler) | To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured. |  | int
| *delay* (scheduler) | Milliseconds before the next poll. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour). | 500 | long
| *greedy* (scheduler) | If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages. | false | boolean
| *initialDelay* (scheduler) | Milliseconds before the first poll starts. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour). | 1000 | long
| *repeatCount* (scheduler) | Specifies a maximum limit of number of fires. So if you set it to 1, the scheduler will only fire once. If you set it to 5, it will only fire five times. A value of zero or negative means fire forever. | 0 | long
| *runLoggingLevel* (scheduler) | The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that. | TRACE | LoggingLevel
| *scheduledExecutorService* (scheduler) | Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool. |  | ScheduledExecutorService
| *scheduler* (scheduler) | To use a cron scheduler from either camel-spring or camel-quartz component | none | String
| *schedulerProperties* (scheduler) | To configure additional properties when using a custom scheduler or any of the Quartz, Spring based scheduler. |  | Map
| *startScheduler* (scheduler) | Whether the scheduler should be auto started. | true | boolean
| *timeUnit* (scheduler) | Time unit for initialDelay and delay options. | MILLISECONDS | TimeUnit
| *useFixedDelay* (scheduler) | Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details. | true | boolean

== Producer Endpoints:

Producer endpoints can use endpoint prefixes followed by endpoint names
and associated options described next. A shorthand alias can be used for
all of the endpoints. The endpoint URI MUST contain a prefix.

Any of the endpoint options can be provided in either the endpoint URI,
or dynamically in a message header. The message header name must be of
the format *`CamelTwilio.<option>`*. Note that the *`inBody`* option
overrides message header, i.e. the endpoint option *`inBody=option`*
would override a *`CamelTwilio.option`* header.

Endpoint can be one of:

[width="100%",cols="20%,20%,60%",options="header"]
|=======================================================================
| Endpoint  | Shorthand Alias | Description
| *creator* | create          | Make the request to the Twilio API to perform the create
| *deleter* | delete          | Make the request to the Twilio API to perform the delete
| *fetcher* | fetch           | Make the request to the Twilio API to perform the fetch
| *reader*  | read            | Make the request to the Twilio API to perform the read
| *updater* | update          | Make the request to the Twilio API to perform the update
|=======================================================================

Available endpoints differ depending on the endpoint prefixes.

For more information on the endpoints and options see API documentation at:
https://www.twilio.com/docs/libraries/reference/twilio-java/index.html


== Consumer Endpoints:

Any of the producer endpoints can be used as a consumer endpoint.
Consumer endpoints can use
http://camel.apache.org/polling-consumer.html#PollingConsumer-ScheduledPollConsumerOptions[Scheduled
Poll Consumer Options] with a `consumer.` prefix to schedule endpoint
invocation. Consumer endpoints that return an array or collection will
generate one exchange per element, and their routes will be executed
once for each exchange.

If you want to receive calls or messages from Twilio and respond to them
using a Camel consumer endpoint, you can use other HTTP-based components
such as *camel-servlet*, *camel-undertow*, *camel-jetty*, and *camel-netty-http*
to respond with https://www.twilio.com/docs/api/twiml[TwiML].


== Message header

Any of the options can be provided in a message header for producer
endpoints with *CamelTwilio.* prefix.


== Message body

All result message bodies utilize objects provided by the Twilio Java SDK.
Producer endpoints can specify the option name for incoming message body
in the *inBody* endpoint parameter.
