Operations 1

Each operation below carries the questions people ask an LLM about it and the instructions they give an agent to run it. Generated by API Evangelist overlay

POST /loyalty/adjustments/bulk Adjust loyalty balances for many customers at once · Perform a Loyalty Adjustment bulk operation #

Ask an LLM

“Can I change the loyalty balance of a whole batch of customers in one request?”

“How do I stop a bulk loyalty adjustment from being applied twice if I resend it?”

Tell an agent

Apply these loyalty balance adjustments to multiple customers in one bulk operation: {adjustments}.

Run the bulk loyalty adjustment {adjustments} with session ID {session_id} so a retry is only applied once.
