Getting Started

In the Syndesis UI navigate to Integrations and click on the Import button in the right top corner. Now you can select the Webhook2Db-export.zip file and start the import. Alternatively you can start with a create a new integration, and select the webhook as it's start connection.

Select JSON Instance and add an example JSON message such as:

{ "task":"some value"}

Click Done, and now add the Postgres SampleDB connection and use

INSERT INTO TODO ( task ) VALUES ( :#task )

Finally add a Datamapper in between and connect

task -> task

Figure 1. Mapping task to task.

Now publish the integration calling it Webhook2Db.

On a succesful deployment it will show an externalURL.

Figure 2. ExternalURL of the webhook.

Put this into your buffer and create a env param like

externalURL=https://i-webhook2db-syndesis.192.168.42.101.nip.io/webhook/knmJINAonaMxWCtMEaR78QIAZbL8RgdVUDVsTDoUaig1IPHvCe

Invoke Webhook

Now invoke the webhook with an HTTP POST using the cmdline utility called curl setting the task to "my new task!"

curl -k --header "Content-Type: application/json" --request POST --data '{ "task":"my new task!"}' $externalURL

You should see the new task in the todo app. You can obtain the URL to this app using

echo https://todo-syndesis.`minishift ip`.nip.io/
