Welcome to the RingCentral Community

"just like I was in the sandbox", did you really change the client id and client secret for your production app? Did you change the server url to point to the production server? I fully trust this error "Invalid resource owner credentials" and I am 100% sure it's a mistake in your params.

Something has changed in the backend, now I am getting a OAU-143

when I search for that in the forum, I get 0 results.

 {
  "error" : "invalid_request",
  "errors" : [ {
    "errorCode" : "OAU-143",
    "message" : "Resource Owner credentials are incomplete"
  } ],
  "error_description" : "Resource Owner credentials are incomplete"
}

I appreciate your concerns , here is my code for the production app

    $SessionUser            =  "+1xxxxxx7873"         
    $SessionPassword        =  "$xxxxxx!"
    $ClientID               =  "9Tlxxxxxxx3uQ"     
    $ClientSecret           =  "hyG_xxxxxxxxx_mjjnQ" 
    $sessionExtension       =  "101"

    $AuthAPI  = @{"endpoint"  = 'https://platform.ringcentral.com/'
                    "url"           = 'restapi/oauth/token' }

										

and here is the code for the sandbox

$SessionUser            =  "+1xxxxxx2434"         
    $SessionPassword        =  "j7MxxxxxxxxxAxf"
    $ClientID               =  "VRbXxxxxxxxxxKM_1Q"     
    $ClientSecret           =  "L4XAKxxxxxxxVY9g" 
    $sessionExtension       =  "101"

    $AuthAPI    = @{"endpoint"      = 'https://platform.devtest.ringcentral.com/'
                    "url"           = 'restapi/oauth/token' }

as you can see I have changed everything to use the production app

could you please verify that #7873 is configured to use this APP thanks for your time

There is nothing wrong with your app. Since you login using the direct number, can you just drop the extension number param.

BTW, not sure how you finally call the endpoint, but your name for the AuthAPI is not correct. url or server_url should be "https://platform.ringcentral.com" and the endpoint is some endpoint such as "restapi/oauth/token".

I dont think there is anything wrong with my code, it is the same code that works in the sandbox, here again is my code, I just removed the extension

Function Get-RingCentralAuthentication { 
    $SessionUser            =  "+1800xxx5041"         
    $SessionPassword        =  "$xxxxxxxxt"
    $ClientID               =  "9TlxxxxxX3uQ"     
    $ClientSecret           =  "hyG_xxxxxxxmjjnQ" 
    $ClientCredsPlainText   = $ClientID + ":" + $ClientSecret
    $ClientCredsBase64      = [System.Convert]::ToBase64String(
                               [System.Text.Encoding]::UTF8.GetBytes($ClientCredsPlainText))
   
    $AuthHeader = @{"Content-Type"  = 'application/x-www-form-urlencoded'
                    "accept"        = 'application/json'
                    "authorization" = "Basic $ClientCredsBase64" }
    $AuthAPI    = @{"endpoint"      = 'https://platform.ringcentral.com/'
                    "url"           = 'restapi/oauth/token' }
    $AuthBody   = @{"grant_type"    = 'password'
                    "username"      = $SessionUser
                    "password"      = $SessionPassword }
    $uri        = $AuthAPI.endpoint + $AuthAPI.url
    $request    = Invoke-RestMethod  -Method POST -Uri $uri -Headers $AuthHeader -Body $AuthBody
    return $request
 
} 

Earlier you showed that you were using the direct number, and that was why I asked you to remove the extension number '101'

$SessionUser = "+1xxxxxx7873"

Now you removed it and changed to use the main company number. Why?

$SessionUser            =  "+1800xxx5041"   

I have been trying eveything, I sent a request to get the main 800# working and they sent this back

"Invalid resource owner credentials" error usually occurs when the credentials are incorrect. Please try logging in to Service web (service.ringcentral.com) using the same credentials (username, Extension and password) you are using to authorize the application to make API calls. If your password is incorrect, you can reset it yourself by clicking the Forgot password link. You can go ahead and do that by clicking on the Forgot Password link. 

Also if your application is in production, you need to switch all your credentials from sandbox to production. 

then after a few hours the error changed on the #7873 from

"Resource Owner credentials are incomplete"

to
"Resource Owner credentials are incomplete"

so I tried the 800#, now both the 800# and #7873 get the same
"Resource Owner credentials are incomplete" error

I think there is something not configured correctly with main number

should this app work on all the extensions, except those set for the Bulk sms?

It should not be the problem with the app.

After all of this, reset password etc., could you still login the service web with the same username and password?

Or can you login this RC app https://app.ringcentral.com using the direct number of the extension 101?

yes, I just test the RC app and logged in with these

800xxx5041 with no extension
800xxx5041 with extension 101
831xxx7873 with no extension
831xxx7873 with extension 101

I also tested with a non-main line number

805xxx4050 with extension 102
805xxx4050 with no extension
all of them worked.

and I have tried all of these in the API

If I use 805xxx4050 with extension 102 I get

  "error" : "invalid_grant",
  "errors" : [ {
    "errorCode" : "OAU-140",
    "message" : "Invalid resource owner credentials"

If I use 800xx5041 or 831xxx7873 with or without an extension I get this different error

 "error" : "invalid_request",
  "errors" : [ {
    "errorCode" : "OAU-143",
    "message" : "Resource Owner credentials are incomplete"

I really dont think this is a password error. If I switch back to the sandbox, it works fine, so I dont think its a coding error

May this be in your case as I see the $ sign in the password?

https://www.rlmueller.net/PowerShellEscape.htm

thats a good catch, but It didnt fix the problem

ok, I changed the password here are the results

with the 800 number with no extension

    $SessionUser            =  "+1800xxx5041"         
    $SessionPassword        =  "hYcxxxxxxajtc"
    $ClientID               =  "9TlxXxxxxX3uQ"     
    $ClientSecret           =  "hyG_xxxxx_mjjnQ" 

"errorCode" : "FeatureNotAvailable",
  "message" : "Phone number doesn't belong to extension",
  "errors" : [ {
    "errorCode" : "MSG-304",
    "message" : "Phone number doesn't belong to extension"

with the 831xxx7873 with no extension

    $SessionUser            =  "+1831xxx7873"         
    $SessionPassword        =  "hYcxxxxxajtc"
    $ClientID               =  "9TlxXxxxxxX3uQ"     
    $ClientSecret           =  "hyG_xxxxxT_mjjnQ" 

  "errorCode":"FeatureNotAvailable",
  "message":"Phone number doesn't belong to extension",
    "errorCode" : "MSG-304",

"errorCode":"FeatureNotAvailable",
  "message":"Phone number doesn't belong to extension",
    "errorCode" : "MSG-304",

What do you mean it did not fix the problem? The new error proves that you could login with the new password. The error says that you are trying to send SMS messages using the "from" number which does not belong to the logged in user.

See our example code, we recommend developers to read the phone number to find the right numbers a user can use for the "from"

async function read_extension_phone_number(){
    try {
        var resp = await platform.get("/restapi/v1.0/account/~/extension/~/phone-number")
        var jsonObj = await resp.json()
        for (var record of jsonObj.records){
            for (feature of record.features){
                if (feature == "SmsSender"){
                    return send_sms(record.phoneNumber)
                }
            }
        }
    } catch(e) {
        console.log(e.message)
        process.exit(1)
    }
}

ok, you are right, I have been trying so many things, when I change the from number #7873 it all worked.. Thanks for you perseverance in helping me. Now If I could get support to let me use the 800# everything would be perfect.

I can't be wrong LOL.

Remember that the #800 is your main company number. You need (if not yet) to set it via the IVR settings to round Fax/SMS messages to the "101" extension in order to send and receive messages from the main company number.

I cant find any setting for SMS in the IVR setting, we have a basic single level IVR

I found your answer to someone else

https://community.ringcentral.com/questions/102801/cannot-send-sms-from-main-company-number.html and tried that, I changed the Operator Extension to 101, but it doesnt allow to use the 800 as the from

Your TF number is not yet provisioned for SMS. Have you submitted a request?

Im trying, this is my last reply, hopefully they understand what I asking

I worked with Phong Vu and he helped me get the code working correctly with 831xxx7873
I would like to be able to be use the  FROM  number to be our main 800xxx5041
Can that be added?

Thank you 

Ken Nye

Actually there is a better way to send a request. Open this link and follow the instructions.

https://gamechanging.dev/sms/

If you do this, you can cancel your previous support ticket.

I did this, it talked about paying for each SMS, I understand the High Volume SMS is extra, but I thought regular SMS is part of the service we already pay for.

No, the regular TF SMS is not free. Same pricing as HV SMS. TF SMS is regulated for non-consumer text messaging. Read this article to learn more.

for some reason even thought it says I have 300 characters left if would not let me post the full post, here is the rest

If I add the extension to 7873

 $SessionUser            =  "+1831xxx7873"         
 $SessionPassword        =  "hYcZxxxxajtc"
 $ClientID               =  "9TlxXxxx0fX3uQ"     
 $ClientSecret           =  "hyG_HxxxxxGqT_mjjnQ" 
 $sessionExtension       =  "101"

  "error":"invalid_grant",
    "errorCode" : "OAU-140",
    "message" : "Invalid resource owner credentials"

If I add the extension to the 800 number

$SessionUser            =  "+1800xxx5041"         
 $SessionPassword        =  "hYxxxxxjtc"
 $ClientID               =  "9Tlxxxxx3uQ"     
 $ClientSecret           =  "hyG_xxxx_mjjnQ" 
 $sessionExtension       =  "101"

  "error" : "invalid_grant",
  "errors" : [ {
    "errorCode" : "OAU-140",
    "message" : "Invalid resource owner credentials"
