Hi @Valerian_Lebert!
It sounds like you have a couple of questions here.
- Is it possible to get the running execution
- Is there a better way to avoid concurrent executions
I hope this article would be helpful to answering your first question: How to get current execution ID in the node - #6 by jan
In regards to preventing concurrent executions, my recommendation is to always strive to make the workflows idempotent. You can also see a few approaches mentioned in this past community thread: Multiple webook calls overlaping - #5 by jan
Happy building!
