Slack 'Send and wait for response' node – How to get Message Timestamp?

Questions
1

Hi,

I’m working with the Slack “Send and wait for response” node and I have a question:
Is it possible to get the Message Timestamp of the message sent from this node?

At the moment, the node only returns true or false depending on the response, but I think if we could also access the timestamp, it would open up more automation possibilities (for example, referencing the message in later steps).

Does anyone know if this is possible with the current configuration of the node, or if there’s any alternative to get it without having to fetch the entire channel history from Slack?

Either way, I believe it would be great to consider this as a future improvement for the node.

Thanks!

No, the Slack “Send and wait for response” node doesn’t give you the message timestamp today. If you need it:

  • Post the message with Slack → Post Message (or HTTP API), get the ts,

  • Then use that ts for reference in later steps.
