Add External ID Field #444
Description
Diode version
v0.6.0
Feature type
New ingestion entity type or new field of existing entity type
Proposed feature or enhancement
Introduce an External ID field that allows Diode to reliably match objects from upstream systems even when their other attributes (name, IP, location, etc.) change. This ID would act as a persistent, source-defined identifier for each asset.
Use case
We synchronize assets from multiple management platforms into NetBox using Diode. Many of these platforms use their own stable identifiers, while operational attributes (like device names or interfaces) may change over time. Without a consistent external ID, Diode can lose track of which NetBox object corresponds to which upstream asset, leading to duplicate objects or failed updates.
