Get available time slots

If the link organizer has configured multiple durations, we'll return all possible time slots for each duration. For example, if the organizer allows schedulers to book either 30 or 60 minutes, then you may see slots that start at the same time (or overlap) with different durations:

[
  {
    start_at: "2021-06-01T00:00:00Z",
    end_at: "2021-06-01T00:30:00Z",
    duration: 30,
    rank: 1
  },
  {
    start_at: "2021-06-01T00:00:00Z",
    end_at: "2021-06-01T01:00:00Z",
    duration: 60,
    rank: 1
  }
]

If the organizer is using ranked availability, then the response may include slots with different rank values:

[
  // A slot with "first" preference
  {
    start_at: "2021-06-01T00:00:00Z",
    end_at: "2021-06-01T00:30:00Z",
    duration: 30,
    rank: 1
  },
  // A slot with "second" preference
  {
    start_at: "2021-06-01T03:00:00Z",
    end_at: "2021-06-01T03:30:00Z",
    duration: 60,
    rank: 2
  }
]

Slots with rank 1 are those the organizer prefers the most. Slots with rank 2 (and higher) will include all the slot times from lower ranks, plus additional times available in that rank. This means if you want to get the "expanded" availability (e.g. up to rank 2), you simply need to filter the list for slots where rank === 2 (not where rank === 1 || rank === 2).

Here's some JavaScript pseudo-code to demonstrate:

const slots = await fetchSlots();

// Includes just the rank 1 times
const preferredAvailability = slots.filter(({ rank }) => rank === 1);

// Includes all rank 1 AND rank 2 times
const expandedAvailability = slots.filter(({ rank }) => rank === 2);

// Includes all rank 1, rank 2 and rank 3 times
const moreExpandedAvailability = slots.filter(({ rank }) => rank === 3);
