  title: Route Mobile SMS Message Sending API
  description: 'Complete API reference for Route Mobile''s SMS platform. Covers message submission,

    OTP, account management, and third-party platform integrations.


    ## Authentication


    Most APIs authenticate via `username` and `password` query parameters.

    Third-party integration APIs (Moengage, Webengage) use a static `Authorization`

    header token provided by Route Mobile.


    ## Base URLs


    | URL | Description |

    |-----|-------------|

    | `https://api.rmlconnect.net` | Secured HTTPS (port 443) — recommended |

    | `https://api.rmlconnect.net:8443` | Secured HTTPS (port 8443) |

    | `http://api.rmlconnect.net` | Non-secured HTTP — legacy only |

    | `https://client.rmlconnect.net` | Client portal — coverage map only |


    ## Platform Response Codes


    SMS submission APIs return a plain text response with a platform status code prefix.


    | Code | Meaning |

    |------|---------|

    | 1701 | Success — `1701\|<CELL_NO>\|<MESSAGE_ID>` |

    | 1702 | Invalid URL / missing or blank parameter |

    | 1703 | Invalid username or password |

    | 1704 | Invalid value in `type` field |

    | 1705 | Invalid message |

    | 1706 | Invalid destination |

    | 1707 | Invalid source (Sender ID) |

    | 1708 | Invalid value in `dlr` field |

    | 1709 | User validation failed |

    | 1710 | Internal error |

    | 1025 | Insufficient credit |

    | 1715 | Response timeout |


    > **Retry Policy:** Do NOT retry for any error code except `1709`.

    > For `1715` specifically, do not re-submit the same message.

      description: 'Submits a single SMS or a batch of SMS messages for delivery over HTTPS.

        Available on both port 443 and port 8443.


        **Long messages:** Messages exceeding standard length are automatically split

        and reassembled on the recipient device. Billing is per segment:

        - Plain text: 153 characters per segment

        - Unicode: 268 characters per segment


        **Bulk response format (multiple destinations):**

        ```

        <Error_Code>|<destination>|<message_id>,<Error_Code>|<destination>|<message_id>,...

        ```


        **Mid-batch abort scenarios:**

        - If any error other than an invalid destination occurs, the batch is aborted immediately.

        - If credits are exhausted mid-batch, processing stops and `1025|<last_destination>` is appended.


        > **Retry Policy:** Do NOT retry for any error code except `1709`.

        > For `1715`, do not re-submit the same message.
