Hi All,

I was working on send SMS from RingCentral API but encountered the below error:

"Parameter [from] value [**********] is invalid [Cannot find the phone number which belongs to user]"

Here are the step that I followed(referred from https://medium.com/ringcentral-developers/use-curl-to-access-ringcentral-platform-api-d4710fe68fa4):

• Created sandbox org
• Got access token
  • curl -i -X POST 'https://platform.devtest.ringcentral.com/restapi/oauth/token'

    -H 'Accept: application/json'

    -H 'Content-Type: application/x-www-form-urlencoded'

    -u '<clientIdFromSandbox>:<clientSecretFromSandbox>'

    -d 'username=<usernameFromSandbox>&password=<password>&extension=&grant_type=password'

• Used Access token to send SMS:

  • curl -i -X POST "https://platform.devtest.ringcentral.com/restapi/v1.0/account/~/extension/~/sms"
    -H "Accept: application/json"
    -H "Content-Type: application/json"
    -H "Authorization: Bearer <access_token>"
    -d '{ "to": [{ "phoneNumber": <to_number> }], "from": { "phoneNumber": <usernameFromSandbox> }, "text": "Hello world!" }'

• One doing this, I received Cannot find the phone number which belongs to user error

Please note that I have a person(Super admin) and it has been assigned with the phone number that I am providing in second API call.

Can anyone help me with this to find if I am missing anything?

Regards,

Brent
