Create a webhook

1. To create a webhook, make a POST request to:

   https://api.vonage.com/t/vbc.prod/vis/v1/self/webhooks/

2. In the body of the request, you will need to enter the following JSON:

    {
     "url": "{YOUR_URL}",
     "events": [
     "CALL"
     ],
     "signingAlgo": "HMAC_SHA256",
     "signingKey": "string",
     "metadataPolicy": "NONE"
   }
   

3. The full curl request will look like the following:

    curl --location --request POST 'https://api.vonage.com/t/vbc.prod/vis/v1/self/webhooks/' \
    --header 'Authorization: Bearer {ACCESS_TOKEN}' \
    --header 'Content-Type: application/json' \
    --data-raw '{
     "url": "https://{NGROK_URL}/webhook",
     "events": [
     "CALL"
     ],
     "signingAlgo": "HMAC_SHA256",
     "signingKey": "string",
     "metadataPolicy": "NONE"
   

4. In the url parameter, you will need to add your accessible URL. This URL will be called by the Vonage Integration Platform API when a call has been updated. A good way to create an accessible URL is to use ngrok to expose a port on your local machine.
