In business automation
A UUID gives each record a number that is very unlikely to collide across systems. In automation, it is used as a key for a lead, order, or request, so events can be matched without relying on a name or a local sequential number.
Examples
These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.
Match a lead from a form with one from a webhook
The form creates an ID when it opens. The same ID is returned in the payment webhook and the CRM update. If the two events arrive out of order, the system updates the same record instead of creating a duplicate based on the name.
Relevant tools
- n8n
- You can generate an ID at the start of the process and pass it to every node. Do not generate a separate ID in each target system without a translation table.
What to check
- Generating a new ID at each step instead of passing the same ID along breaks the chain.
