To schedule a message for later sending, first include the parameter 'scheduledatetime'. This should be in the format:

YYYY-MM-DD HH:MM:SS
  • This parameter must be URL encoded

  • The time must be in AEDT

An example request containing this parameter might look like the following:

https://api.smsglobal.com/http-api.php?action=sendsms&user=USERNAME&password=PASSWORD&to=61447100250&from=SMSGlobal&text=Hello!&scheduledatetime=2021-06-09%2015%3A00%3A00

Note: as usual, you will want to URL encode this scheduledatetime parameter.

Note: For USERNAME and PASSWORD in the abov, use your Master API Keys.


​For example, 2021-06-09 15:00:00 would represent 9 June, 2021, at 3pm (AEDT).

When the message is successfully scheduled, the API will print out a delayed message ID in the format:

​SMSGLOBAL DELAY MSGID:1203396573


Note:

The actual SMS message IDs are only generated once the message is sent.

Note:

When sending Unicode messages using HTTP API, it is necessary to Triple URL encode the message to avoid any encoding issues.
