RingCentral Permahooks

This is a small app that turns RingCentral's expiring outbound webhooks into non-expiring webhooks. This is especially useful when connecting to a service with a simple inbound webhook implementation such as Zapier and chat solutions like Glip. Benefits include:

• Seamlessly links RingCentral Outbound Webhooks with Inbound Webhooks offered by Zapier, Glip and others.

This is useful because RingCentral's webhook implementation has a couple of features that are not supported by all webhook consuming services. Both of the below are handled automatically by this service.

• RingCentral requires the webhook endpoint return the request Validation-Token header in the response to indicate the receiving endpoint is the correct one.
• RingCentral webhooks expire to ensure the correct site is receiving the information.

Deployment options:

• Run locally: only the main.go file is necessary as shown below.
• Lambda: TBD, will use aws/aws-lambda-go like Chathooks

See more information about creating RingCentral webhooks here:

• API Reference: https://developer.ringcentral.com/api-docs/latest/index.html#!#RefCreateSubscription
• Developer Guide: http://ringcentral-api-docs.readthedocs.io/en/latest/webhooks/

Pre-requisites

You must have created an app on the RingCentral Developer Platform by logging into the Developer Portal:

https://developer.ringcentral.com

The app must have the following settings:

• Application Type: Private
• Platform Type: Server-only (No UI)
• OAuth Grant Types: Refresh Access Token, Password flow
• Permissions: Read Messages, Webhook Subscriptions

In the Developer Portal, your app will look like this.

Installation and Configuration

Before you can complete the following installation procedure, you need to get a webhook URL from your downstream service. For example, a Zapier webhook URL.

$ go get github.com/grokify/ringcentral-permahooks
$ cd $GOPATH/src/github.com/grokify/ringcentral-permahooks
$ cp sample.env .env
$ vi .env
$ go run main.go

After you start the service, create a webhook by calling the /createhook endpoint. You can also call the /renewhook endpoint to manually renew the webhook. For example:

# Create Webhook
$ curl -XGET 'https://12345678.ngrok.io/createhook'

# Renew Webhook
$ curl -XGET 'https://12345678.ngrok.io/renewhook'

Successfully calling /createhook will result in log entries like the following:

$ go run main.go 
INFO[0023] Creating Hook...

INFO[0025] Created/renewed Webhook with Id: 11112222-3333-4444-5555-666677778888

Tunneling

If your server is behind a NAT or a firewall and not accessible via the Internet, you can use a tunneling service such as ngrok. In the following example, you would create a RingCentral webhook to https://12345678.ngrok.io/webhook which you would set as PERMAHOOKS_INBOUND_WEBHOOK_URL in your environment.

$ ngrok http 8080
