MMS Gateway - RingCentral

The RingCentral MMS Gateway currently delivers MMS messages internationally. You can use the following methods for attaching media files to your outgoing messages:

  • Gateway Direct: fmMMS will upload the file stored in the FileMaker container field directly to RingCentral.

You can get further information on supported media files and limitations here:

https://developers.ringcentral.com/guide/messaging/sms/sending-images#creating-attachments

fmMMS supports both the RingCentral Sandbox (testing environment) as well as the live Production environment. We recommend testing initially using the Sandbox if you are new to RingCentral and creating separate records in the fmMMS Accounts table for the Sandbox and Production environments.

To use fmMMS with RingCentral you will need the following:

  • your RingCentral Sandbox or Production username
  • your RingCentral Sandbox or Production password
  • your RingCentral Virtual Number

You will also need to create a RingCentral app on the RingCentral website to use with fmMMS. When you create the RingCentral app select the Web server option and ‘Only members of my organisation/company’ for access (private app option). Detailed instructions can be found on the RingCentral website here. When creating the RingCentral app make sure you select the following permissions:

  • Read Messages
  • SMS
  • Webhook Subscriptions

Once you have created your RingCentral app you will also need:

  • your RingCentral app Client ID
  • your RingCentral app Client Secret

You can then create an Account record in the fmMMS file and select RingCentral as the Gateway to use from the drop down menu and complete the following details:

  • enter your RingCentral Phone number linked to account or extension in the Username field in the Accounts Screen
  • enter your RingCentral Password in the Password field in the Accounts Screen
  • enter your RingCentral Virtual Number in the Custom Text 1 field in the Accounts screen

The Accounts screen should look like this:

RingCentral uses OAuth for authenticating with the RingCentral API, so you will also need to enter your OAuth credentials that were generated as part of creating the RingCentral app. You can view your OAuth Credentials on the RingCentral website (go to Console/Apps and click on your app and then Credentials):

In the fmMMS Accounts screen click the OAuth Settings button:

which opens a FileMaker popover where you can enter your OAuth credentials:

  • enter your RingCentral app Client ID into the Client ID field
  • enter your RingCentral app Client Secret into the Client Secret field
  • select the Environment to use (Sandbox or Production)

You can ignore the other fields as they will be populated automatically as you authenticate or when the access token is refreshed. We are not using the Redirect URL as we are using the Password Auth Mode.

When you have finished testing in the RingCentral Sandbox you can graduate your app for use in the Production environment – see the RingCentral website for more details on this process.

Incoming Messages/Replies

You can get incoming messages/replies to your RingCentral number into the fmMMS file in 2 ways:

  • Manually Download Incoming Messages
  • Use Webhooks to have RingCentral push these automatically to fmMMS

Using Webhooks is the preferred method as it saves you from having to poll/check for any new messages - with Webhooks new messages are forward to fmMMS automatically by RingCentral as they are received.

Manual Download Incoming Messages

You can download incoming SMS messages manually via the Account Details screen. Simply enter the date range you wish to download messages between and click the Get Incoming Messages button:

Any incoming MMS messages to your RingCentral number that have not been previously downloaded will then be downloaded. You could also setup a FileMaker Server script schedule to have this run on a scheduled basis (e.g.every hour) to save you from having to manually download/check for new messages.

RingCentral Webhooks Setup

The RingCentral API supports using Webhooks to receive incoming SMS messages, however you have to use the RingCentral API to create the Webhook. We have added support for creating and deleting Webhooks using the RingCentral API in the fmMMS file. You can get more information on the requirements for Webhooks with RingCentral here (e.g. it must be hosted on an SSL secured site and start with https).

To receive incoming MMS messages to your RingCentral number, including replies to previously sent messages, you will need to use the supplied WebhooksIncomingMessages.php webhook file to act as the webhook receiver. See our Webhooks guide for what you need to do host the WebhooksIncomingMessages.php file on your chosen web server. Once you have the publicly accessible URL for this file click on the Webhooks tab in the fmMMS Account Details screen and click the Create Webhook button:

Enter the https URL to your dedicatedNumberReply.php file in the Address field and select Incoming Messages for the Type field. The Webhook details should look something like this:

Click the Create Webhook button to create a Webhook using the RingCentral API. If this request was successful the RingCentral Webhook ID will be populated in the Gateway ID field, otherwise you will get an error message in the Last API Result field. Once you have successfully created the Webhook any new incoming messages will be forwarded by RingCentral to that URL. N.B. RingCentral Webhooks do expire – we set the expiration time to 157680000 seconds (5 Years) when creating the Webhook using the fmMMS file.
