Since IBM shared performance concerns at scale while using webhooks we decided to consider other approaches for enforcing fields immutability.

DoD:
We need to:

• Audit the whole API. Decided what’s immutable and what’s not.
• Discuss and agree on the implementation approach.
• Implement it.

We could run webhooks as an optional component and let it be a consumer choice to run them.

Alternatively the implementation could be based on having status as the source of truth for immutable fields.
