Hi @Gilles_Verbecq ,
Do you also use ProspectIn with n8n ?
If I remember they are using the same kind of webhook with Piwaa & ProspectIn. The main issue with their solution is that you can only wait 12 or 24h to receive and test their webhooks (this is why I leave them).
If you want to debug and test your workflow, why don’t you use a google sheet to get the results (and check them) before sending them to your CRM ?
I have the habits to do it to be sure that my data are clean and ready to be load.
Don’t hesitate to tell us if you succeed in doing it
