What is n8n?

n8n is a development tool for workflow automation. By combining different nodes you can create different workflows for numerous scenarios.


SMS dispatch

Add the sms77 node to your workflow to send SMS. The possibility to combine it with other nodes enables you to build workflows for all kinds of use cases.

Dispatch text-to-speech messages

Add the sms77 node to your workflow for making text-to-speech calls. With this node the given text gets converted to a speech message which gets read out loud after the given recipient number has answered the call. This node too gives you the chance combining it with other nodes for realizing complex scenarios for all kinds of use cases.


The sms77 node is available in n8n, a separate installation is not necessary.

Example SMS dispatch

Pass whatever text to the node allows sending the message to any number of recipient(s) of choice.
