This document is intended as a guide for messages sent through the new WhatsApp messaging via FTP format

  • The file format was based on sending an SMS file via FTP.

To trigger messages via FTP, you must generate a file with the formatting in the example below:

HSM Message:


1st line:

Send date (for scheduling cases)

Start send time (for scheduling cases)

End send time (for scheduling cases)

Message type must be: HSM

HSM name (elementName)

HSM language (languageLocale)

HSM language Deterministic or Fallback (languagePolicy)

name of HSM parameters

Notes for the first line:

  1. Parameter names must match the column names

  2. Information that will not be used may be left blank, however you should keep the semicolon as separation. Example of a case where we did not use scheduling (the first fields are between semicolons and have no information within): ; ; ; HSM;chatclub_welcome;pt_BR;DETERMINISTIC;name|company

  3. By default, the languagePolicy will be Deterministic.

  4. The names of HSM parameters should be separated by " | " and not by " ; "

2nd line:

Column names

3rd and remaining lines:

Recipient and values of HSM parameters
