Sending Messages (SFTP)
Sending messages is very simple. First, create your files in the correct file format and then transfer them to the SFTP server.
File Format
| File Types | JSON formatted files are supported with either the .txt or .json file extensions. Correctly formatted data is expected to process uploaded files. |
| Unique File Names | File names should be unique. This prevents against duplicate files as only unique file names are processed. The .zip file names don’t need to be unique. File name uniqueness is only checked for 48 hours. |
| File Extensions | Only .zip .txt .json file extensions are allowed. |
| File Encoding | Files should be encoded using UTF-8 |
| Zipped Files | We recommend zipping all .txt and .json files for size reduction and CRC checks. This is a great way to ensure that the complete file is uploaded and processed correctly. |
| Character Sets | Before creating your files, please view our supported SFTP to SMS Character set. |
File Upload
1. Log in to the SFTP Server.
2. Transfer your file to the “Send_SMS” folder.
3. Within 5 seconds, the file will be processed by SFTP to SMS automatically.
4. A file upload status will be sent to the email address specified in the file. If no email address is
specified, the account email is used.
