RCHooks - RingCentral Webhook Tools

rchooks is a toolset for creating, listing, recreating, and deleting RingCentral webhooks. It is especially useful in development when working with ngrok and when webhooks are blocked when test servers are taken down and non-responsive. It includes the following:

• rchooks CLI app
• keepalive_lambda AWS Lambda function to check and rebuild webhook when blacklisted
• rchooks SDK package for utilities to build your own apps

Apps

CLI App

CLI Installation

$ go install github.com/grokify/rchooks/cmd/rchooks
$ rchooks --env=/path/to/.env --list

Prior to Go 1.18, use go get:

$ go get github.com/grokify/rchooks/cmd/rchooks
$ rchooks --env=/path/to/.env --list

CLI Usage

By default, rchooks looks for an environment file path specified by the ENV_PATH environment variable or a .env file in the current working directory. You can also explicitly specify a .env file with the --env path parameter.

$ rchooks --list
$ rchooks --create=https://example.com/webhook
$ rchooks --recreate=https://example.com/webhook
$ rchooks --recreate=11112222-3333-4444-5555-66667777888
$ rchooks --delete=https://example.com/webhook
$ rchooks --delete=11112222-3333-4444-5555-66667777888

Configure OAuth by setting the oauth2more/credentials file via --creds and the account via --account.

Set the following enviroment variables:

• RINGCENTRAL_WEBHOOK_DEFINITION_JSON - Create subscription JSON body

An example value for RINGCENTRAL_WEBHOOK_DEFINITION_JSON can be the following. For a long lived webhook, use a value like 500000000 seconds which is equivalent to 15.85 years.

{
  "eventFilters":[
    "/restapi/v1.0/glip/posts",
    "/restapi/v1.0/glip/groups",
    "/restapi/v1.0/account/~/extension/~/message-store/instant?type=SMS"
  ],
  "deliveryMode":{
    "transportType":"WebHook",
    "address":"https://12345678.execute-api.us-east-1.amazonaws.com/prod/webhook"
  },
  "expiresIn":500000000
 }

Compact example:

{"eventFilters":["/restapi/v1.0/glip/posts","/restapi/v1.0/glip/groups","/restapi/v1.0/account/~/extension/~/message-store/instant?type=SMS"],"deliveryMode":{"transportType":"WebHook","address":"https://12345678.execute-api.us-east-1.amazonaws.com/prod/webhook"},"expiresIn":500000000}

Build the lambda function and then upload to AWS:

$ go get github.com/grokify/rchooks
$ cd $GOPATH/src/github.com/grokify/rchooks/apps/keepalive_lambda

Set the following enviroment variables:

• RINGCENTRAL_TOKEN - JSON string or simple access token string
