Solutions

List team event types via GET /v2/event-types?teamSlug={teamSlug} to confirm the slug before booking.
If the team is inside an organization, add organizationSlug so the 324 branch resolves.
Verify teamSlug casing and remove trailing whitespace.
Confirm the event type is published and assigned to the team.

Example fix

// before
body: { teamSlug: 'Sales ', eventTypeSlug: 'demo' }

// after
body: { teamSlug: 'sales', eventTypeSlug: 'demo' }

Defensive patterns

Strategy: validation

Validate before calling

const teamSlug = body.teamSlug?.trim().toLowerCase();
const eventTypeSlug = body.eventTypeSlug?.trim();
const et = await api.get(`/v2/event-types?teamSlug=${encodeURIComponent(teamSlug)}`);
if (!et.data.some(e => e.slug === eventTypeSlug)) throw new Error('team event type not found');

Type guard

const hasTeamSlugCombo = (b: CreateBookingInput): boolean =>
  !!(b.teamSlug && b.eventTypeSlug && !b.organizationSlug);

Try / catch

try { await api.post('/v2/bookings', body); }
catch (e) {
  if (e.response?.status === 404 && /belonging to team/.test(e.response.data.message)) {
    /* verify teamSlug casing or add organizationSlug if team is org-scoped */
  } else throw e;
}

Prevention

Confirm the team slug casing and ownership before booking.
Add organizationSlug when the team is inside an organization.
Pre-fetch team event types to validate the slug.

When it happens

Trigger: POST /v2/bookings with { teamSlug, eventTypeSlug } where the team slug is wrong, the event type is not owned by that team, or the team is inside an organization (which requires organizationSlug and triggers the 324 branch instead).

Common situations: Team was renamed; event type reassigned from one team to another; team lives inside an org but the caller omitted organizationSlug; team event type is unpublished; slug casing mismatch (team slugs can be case-sensitive).
