Webhook
Since Camel 3.0
Only consumer is supported
The Webhook meta component allows other Camel components to configure webhooks on a remote webhook provider and listening for them.

Maven users can add the following dependency to their pom.xml
for this component:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-webhook</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>Typically other components that support webhook will bring this dependency transitively.
Webhook Options
The Webhook component supports 8 options, which are listed below.
| Name | Description | Default | Type |
|---|---|---|---|
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 |
webhookAutoRegister (consumer) |
Automatically register the webhook at startup and unregister it on shutdown. |
true |
boolean |
webhookBasePath (consumer) |
The first (base) path element where the webhook will be exposed. It’s a good practice to set it to a random string, so that it cannot be guessed by unauthorized parties. |
String |
|
webhookComponentName (consumer) |
The Camel Rest component to use for the REST transport, such as netty-http. |
String |
|
webhookExternalUrl (consumer) |
The URL of the current service as seen by the webhook provider |
String |
|
webhookPath (consumer) |
The path where the webhook endpoint will be exposed (relative to basePath, if any) |
String |
|
autowiredEnabled (advanced) |
Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. |
true |
boolean |
configuration (advanced) |
Set the default configuration for the webhook meta-component. |
WebhookConfiguration |
The Webhook endpoint is configured using URI syntax:
webhook:endpointUri
with the following path and query parameters:
Path Parameters (1 parameters):
| Name | Description | Default | Type |
|---|---|---|---|
endpointUri |
Required The delegate uri. Must belong to a component that supports webhooks. |
String |
Query Parameters (9 parameters):
| Name | Description | Default | Type |
|---|---|---|---|
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 |
webhookAutoRegister (consumer) |
Automatically register the webhook at startup and unregister it on shutdown. |
true |
boolean |
webhookBasePath (consumer) |
The first (base) path element where the webhook will be exposed. It’s a good practice to set it to a random string, so that it cannot be guessed by unauthorized parties. |
String |
|
webhookComponentName (consumer) |
The Camel Rest component to use for the REST transport, such as netty-http. |
String |
|
webhookExternalUrl (consumer) |
The URL of the current service as seen by the webhook provider |
String |
|
webhookPath (consumer) |
The path where the webhook endpoint will be exposed (relative to basePath, if any) |
String |
|
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. There are 3 enums and the value can be one of: InOnly, InOut, InOptionalOut |
ExchangePattern |
|
synchronous (advanced) |
Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). |
false |
boolean |
You can append query options to the URI in the following format, ?options=value&option2=value&…
Examples
Examples of webhook component are provided in the documentation of the delegate components that support it.
Spring Boot Auto-Configuration
When using webhook with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:
<dependency>
<groupId>org.apache.camel.springboot</groupId>
<artifactId>camel-webhook-starter</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
</dependency>The component supports 9 options, which are listed below.
| Name | Description | Default | Type |
|---|---|---|---|
camel.component.webhook.autowired-enabled |
Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. |
true |
Boolean |
camel.component.webhook.bridge-error-handler |
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 |
camel.component.webhook.configuration |
Set the default configuration for the webhook meta-component. The option is a org.apache.camel.component.webhook.WebhookConfiguration type. |
