parameterise email "To" in node-red

I want to pass (actually want to loop in) email addresses (multiple) to email node. How I can achieve this. By default it taking only body of email as parameter and "TO" address is hard coded in node property file.

Thanks,

Solution

  • There is a rule for all the core Node-RED nodes (it should also be followed by other nodes, but not always) that says if you add an option in the config dialog then it can not be overridden by incoming msg properties.

    If you leave the To field empty when configuring the node it should pick it up from the msg.to field on the incoming message.

    If you have an array of addresses you should be able to use something like the slit node to break it up into separate message to pass into the email node (probably via a change node to rearrange the fields).
