Issue:When calling the /oauth/token API to authorize your application, you may encounter the following error:{ "error": "unauthorized_client", "error_description": "Unauthorized for this grant type"}Possible Causes: Your application is attempting to use a grant type (e.g., Authorization Code Flow or JWT) that is not configured in your app settings. There is an error in your implementation of the selected grant type. You are using a grant type that is no longer supported. Important Notice: Password Grant Type No Longer SupportedRingCentral no longer supports the Password Grant type. If your application was previously using it, you must update to JWT or another supported grant type.Resolution Steps: Check your application's settings to ensure your code is using an OAuth grant type that is correctly configured. Use a RingCentral SDK to handle the authorization process. If implementing OAuth manually, ensure that your implementation follows the correct technical requirements. Add

Can I set http://localhost/ringcentral/index.php as my OAuth Redirect URI?I am using the following authorization flows: Authorization Code Refresh Access Token I do not have a live, publicly accessible URL for my OAuth Redirect URI. How can I complete the OAuth process?Answer:Yes, you can set a Redirect URI to your localhost. Since OAuth redirects are processed by your browser, which has access to localhost, this setup works for local development.However, if your application uses webhook subscriptions, you will need a publicly accessible URL to receive event notifications. The recommended approach is to use a reverse proxy to expose a public URL that tunnels requests to your localhost application.Recommended Solution:We recommend using ngrok, a widely used reverse proxy tool among developers. Ngrok provides a temporary public URL that securely routes requests to your local environment, allowing webhook events to reach your application.By using this approach, you can successfully comp

RingCentral provides multiple API endpoints to access your communication history, depending on the type of communication you wish to audit.Auditing Phone CallsTo review a history of your company's phone calls, use the Call Log API.

Issue: Users need the ability to send a single SMS message to a list of 50 or more phone numbers quickly and efficiently without manually entering each number.Background: Due to increasing regulations and consumer protections, carriers have implemented strict guidelines to prevent SMS spam and fraud. As of 2022, businesses must register their brand and messaging campaigns through a process known as The Campaign Registry (TCR) before sending bulk SMS messages.Solution: To send mass SMS messages while complying with regulations, follow these steps: Register Your Business and Campaign: Businesses sending SMS at scale must complete the TCR registration process. RingCentral reviews applications before submitting them for carrier approval. Use High-Volume SMS Solutions: RingCentral provides solutions for sending bulk messages efficiently.

Issue: When using the PHP SDK to send SMS messages, sending to a single recipient works fine. However, attempting to send to multiple numbers results in the following error:Business operation is not supported.Cause: Currently, the API restricts SMS messages to a single recipient per request to prevent unsolicited SMS messages.Solution: If you need to send SMS messages, ensure that you only include one recipient per API request. You can find the official API documentation for sending SMS here: RingCentral SMS API DocumentationUsing High Volume SMS API: If you need to send SMS messages to multiple recipients externally, consider using the High Volume SMS API. This API is designed for bulk messaging and allows you to send messages to multiple recipients efficiently. Refer to the documentation for more details: High Volume SMS API Documentation

You are receiving unexpected subscriptions created daily at 3 AM, likely due to an automated process (such as a cron job) from an unknown source, possibly implemented by a previous developer. You want to reset the client secret without disrupting the production app. Additionally, you would like to identify the origin of the unauthorized subscriptions.Solution: Currently, there is no way to reset an application’s client secret directly. To resolve this issue without disrupting your production app, follow these steps: Clone Your Existing Application: Cloning the application will generate a new client ID and client secret. This ensures that you have a fresh set of credentials to use for your legitimate production instance. Update Your Production App with the New Credentials: Replace the old client ID and client secret with the newly generated ones in your application. Verify that your application continues to function properly with the new credentials. Suspend the Ol

Every time a call gets parked via a desk phone, it causes a notification alert (sound) in the RingCentral PC app to go off. It appears to be tied to the "Direct messages" notification sound. When I change the direct messages notification sound, it also changes the parked call notification to match that sound, which is really annoying as I think I'm receiving a direct message every time someone parks a call. I would like to be able to adjust the Call Park notification sound via its own setting without effecting the Direct messages sound. Ideally, I would like to be able to turn the park notification off all together, but keep the direct message notifications on.

It seems that some updates have been pushed out recently regarding the Hubspot/RingCentral connection. Anyone have any kind of documentation on best practices for setup? I like how they moved the dialing window to be housed within RingCentral directly but our teams are encountering what seems to be a lot of bugs. Can anyone help? Also looking for some kind of documentation on what has been updated in the latest release.

How do you transfer a call on a Yealink W79P Cordless Phone?

Recently RC has stopped offering the normal Polycom ATA devices we use for fax machines. I was told the Cisco ATA 192 would offer the same functionality.On multiple devices we have discovered that the internet out port on the device (labelled as "Ethernet" on the device) does not seem to function. I have spent the last week plus poking around in the online configuration utility and I cannot get this to work. I can get the device online, I can fax in and out, everything works other than the port on the device that is supposed to be used for another device to access the web will not allow a connection. I believe this has something to do with the IP address on the port being assigned to a weird value.I am still waiting on a solution from RC Support. This has stopped all fax conversions currently so hoping that either 1) there is a solution already from someone on this board or 2) help others who are stuck with this issue.

Does RingCentral work for Salesforce Platform Licence User?

Our team members, using both iPhones and Androids, keep accidentally hanging up calls with their cheeks. Since this happens across both device types, I don’t think it’s a proximity sensor issue.Does anyone have suggestions on how to prevent this?Thanks!

I’m on my 7th go round on this.  My latest message is now:  Insufficient detail provided for Consent section when opt-in consent occurs outside of websiteCan anyone please provide some insight on what this means?  Is this a matter of adding another line to a privacy policy?  We dont use texting for marketing or cold reaching out.  This has been a nightmare without guidance.

We use the RingCX progressive dialer. I've uploaded a list of contacts for our agents to call. How can I export or download a list of contacts completed or not completed by our agents?

When using RingCentral add in to Pipe drive I am able to see when we make calls out in the log. However when we have incoming calls it is not showing up in the log.

My users are having trouble sending attachments. They don’t receive any warning about attachment size (and the file is only a small image). The text of the message goes through just fine, but the attachment seems to disappear. Is anyone else experiencing this issue?

Is there a way to bulk delete text messages?In the old windows app, you could select multiple threads and delete them all at once. Now you have to go through and delete one by one. I send/receive hundreds of texts per day so it takes a lot of time to clean out my inbox.

I opened a case on 3/20 and there is no indication it has been seen. The case has a New status and there are no replies from RC support.Will a mod please help me? I can msg my case number or whatever else you need.Thank you.
