I am using SFMC Rest API to send SMS. I have used API Trigger send type in mobile connect with outbound message template. I am using postman.

Prob : Below is the URL which i am using in the postman to trigger the sms. https://yourdomain.rest.marketingcloudapis.com/sms/v1/messageContact/{APIKEY}/send

In response i am getting a TokenID and according to documentation if the request is valid then you get this tokenid. But i am not getting the SMS.

On checking the status using the URL mentioned below which utilizes this tokenID. response is "Unknown"


if anyone knows please help here.

See the request below :

    "Subscribers": [
        "MobileNumber": "9199xxxxxxxx",
        "SubscriberKey": "123456789"
    "Subscribe": "false",
    "Resubscribe": "false",
    "Override": "false",
    "SendTime": "2019-03-25 18:59"

Please check if the contact you are trying to reach exists in Mobile Connect.

You have "Subscribe":"False" setting enabled and you shouldn't be able to send to the mobile number if the contact isn't already there.

If you switch this value to "True", when the API call will reach Marketing Cloud it will create a new MobileConnect contact and a subscription on a given keyword (when this setting is true, you need to include a keyword parameter).

All in all you have two options:

  1. Create the contact you are trying to reach in MobileConnect
  2. Switching "Subscribe" to "True" and adding a keyword parameter that will create a contact and subscription in MC.
  • Thanks for your comments!! Because subscriber had been added manually, the status field was not getting populated. After assigning code and keyword to add subscription of the contact in the contact builder, the problem resolved. Thanks everyone.
