How HumDay uses it

1. You describe the outcome. Not this operation by name — what you want to happen. HumDay works out which operations it needs.
2. The contract names it. Before anything is built, you see exactly which Walmart Orders operations the program may use, and this is one of them.
3. You approve access. Because this one changes data, it cannot run until you have explicitly granted it.

Questions

Can HumDay cancel order lines in Walmart Orders?

Yes. This operation is published in Walmart Orders's own API description, so HumDay can use it without a hand-built connector — once you have approved it for your automation.

Will this change my Walmart Orders data?

Yes — this is a POST operation, so it changes something in Walmart Orders. HumDay holds anything that writes behind an approval you grant explicitly, and the contract you approve says what it may touch.

Do I need to write code?

No. You describe the outcome you want in plain words. HumDay agrees a contract with you, writes the program, and shows you a proof run before anything touches your Walmart Orders account.
