Agreed [with my rationale below] Answer: 1. Web Application 2. PATCH /bookings/ABCEDF {"bookedBy": "alice"} 3. 204 NO CONTENT 4. webhook listener 5. for each listener 6. POST <listener.uri> {"bookingId": "ABCDEF"} Rationale for each (in the order I figured them out while working through the problem) 1. [prompt says from a web application] 2. [this matches what displays on the right-hands side, where it does something for the alice booked by 5. [would do looping referred to on the right] 4. [this is about a webhook listener, and it would logically precede #5] 6. [this correspondes to the uris on the right-hand side that the SELECT retrieved ... so that your loop is doing something with them] 3. [this is the only one left, and it fits]

Note: From the service's perspective, a 204 (No Content) response may be a perfectly valid response to a POST, PUT or DELETE request.

After debating about the answer, I also agree with the order shared by moslig. 204 http response is common for update operation (PATCH), using POST operation, we normally received 200 or 201 responses. Although having the POST at the end does not make any sense to me, however by discarding, that the best place for this option.
