I would like to suggest updating the ClickSend API to version 3.
Version 3 of the REST API allows sending MMS as well as SMS.
Being able to send pictures from Ruko using clicksend would be a great feature to have.
It could also use automated actions and the image field to attach images to the message.
See the documentation for it here.
https://developers.clicksend.com/docs/rest/v3/#send-mms
It can also convert unsupported image files into supported image files using the uploads endpoint as seen below.
