Camel-Kafka-connector Braintree Sink

This is an example for Camel-Kafka-connector Braintree Sink

Standalone

What is needed

  • A Braintree account

  • At least one customer registered in Braintree account

Setting up Braintree

In this example we’re using a Sandbox environment coming from Braintree. In the UI of your sandbox create a customer and take note of his id.

Running Kafka

$KAFKA_HOME/bin/zookeeper-server-start.sh $KAFKA_HOME/config/zookeeper.properties
$KAFKA_HOME/bin/kafka-server-start.sh $KAFKA_HOME/config/server.properties
$KAFKA_HOME/bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic mytopic

Setting up the needed bits and running the example

You’ll need to setup the plugin.path property in your kafka

Open the $KAFKA_HOME/config/connect-standalone.properties

and set the plugin.path property to your choosen location

In this example we’ll use /home/oscerd/connectors/

> cd /home/oscerd/connectors/
> wget https://repo1.maven.org/maven2/org/apache/camel/kafkaconnector/camel-braintree-kafka-connector/0.11.5/camel-braintree-kafka-connector-0.11.5-package.tar.gz
> untar.gz camel-braintree-kafka-connector-0.11.5-package.tar.gz

Now it’s time to setup the connectors

Open the Telegram sink configuration file

name=CamelBraintreeSinkConnector
connector.class=org.apache.camel.kafkaconnector.braintree.CamelBraintreeSinkConnector
key.converter=org.apache.kafka.connect.storage.StringConverter
value.converter=org.apache.kafka.connect.storage.StringConverter

topics=mytopic

camel.sink.path.apiName=customer
camel.sink.path.methodName=delete
camel.sink.endpoint.inBody=id
camel.sink.endpoint.environment=sandbox
camel.sink.endpoint.publicKey=<public_key>
camel.sink.endpoint.privateKey=<secret_key>
camel.sink.endpoint.merchantId=<merchant_id>

Set the correct options in the file.

Now you can run the example

$KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties config/CamelBraintreeSinkConnector.properties

You should have taken note of the customer id in the first steps, now it’s time to use it.

> echo "264512693" | ./kafkacat -b localhost:9092 -t mytopic
% Auto-selecting Producer mode (use -P or -C to override)

In your log you should see something like this:

Now the customer has been removed from your Braintree account.
