What are Code Snippets?
Code snippets are short pieces of code you can reuse in your own applications. The code snippets use code from example repositories.
Please read this information carefully before attempting to use the code snippets.
Prerequisites

Replaceable variables
Replace the following values in the code snippets with your own details:
| Key | Description |

VONAGE_API_KEY |
API key. |
VONAGE_API_SECRET |
API secret. |
INSIGHT_NUMBER |

Webhooks
The Basic and Standard levels of the Number Insight API are synchronous and do not require webhooks.
The Advanced level of the Number Insight API enables you to optionally deliver an asynchronous POST response to a webhook when the data becomes available.
In the code snippets, the webhook is located at /webhooks/insight. If you are using Ngrok, the webhook you need to configure in your client is of the form https://demo.ngrok.io/webhooks/insight. Replace demo with the subdomain provided by Ngrok.
