Can someone tell me, categorically, which identifier(s) are immutable for each Pipefy Object;

• Pipe
• Phase
• Card
• Field

When discussing “Fields”, my understanding is that “field_id” or “id” is reliably immutable. However, there are other identifiers “internal_id”, “index” and “uuid” each of which would suggest they too could be immutable.

Thanks for any help
