Webhook action

The webhook automation stitch action makes HTTP and HTTPS requests to a specified server, with custom headers, bodies, ports, and methods. It can be used to leverage the ubiquity of HTML requests and APIs to integrate with other tools.

The URI and HTTP body can use parameters from logs or previous action results. Wrapping the parameter with %% will replace the expression with the JSON value for the parameter, for example: %%results.source%% is the source property from the previous action.

In this example, a specific log message (failed administrator log in attempt) triggers the FortiGate to send the contents of the log to a server. The server responds with a generic reply. This example assumes that the server is already configured and able to communicate with the FortiGate.

To configure the webhook automation stitch in the GUI:

1. Go to Security Fabric > Automation and click Create New.
2. Enter the stitch name (badLogin).
3. Configure the trigger:
   1. Click Add Trigger.
   2. Click Create and select FortiOS Event Log.
   3. Enter the following:

      Name	badLogin
      Event	Admin login failed

   4. Click OK.
   5. Select the trigger in the list and click Apply.
4. Configure the automation stitch action:
   1. Click Add Action.
   2. Click Create and select Webhook.
   3. Enter the following:

      Name	Send Log To Server
      Protocol	HTTP
      URL	172.16.200.44
      Custom port	Enable and enter 80
      Method	POST
      HTTP body	%%log%%
      HTTP header	Header : 1st Action

      

   4. Click OK.
   5. Select the action in the list and click Apply.
5. Click OK.

To configure the webhook automation stitch in the CLI:

1. Create an automation trigger:

   config system automation-trigger
       edit "badLogin"
           set event-type event-log
           set logid 32002
       next
   end

2. Create the automation action:

   config system automation-action
       edit "Send Log To Server"
           set action-type webhook
           set uri "172.16.200.44"
           set http-body "%%log%%"
           set port 80
           set headers "Header:1st Action"
       next
   end

3. Create the automation stitch:

   config system automation-stitch
       edit "badLogin"
           set trigger "badLogin"
           config actions
               edit 1
                   set action "Send Log To Server"
                   set required enable
               next
           end
       next
   end

To test the automation stitch:

1. Attempt to log in to the FortiGate with an incorrect username or password.
2. On the server, check the log to see that its contents were sent by the FortiGate.

   

   The body content is replaced with the log from the trigger.

3. On the FortiGate, go to Log & Report > System Events to confirm that the stitch was activated.
4. Go to Security Fabric > Automation to see the last time that the stitch was triggered.
