Creates an organization term (semester/period) with start and end dates. `termStart` must be strictly before `termEnd`. Optionally set election and reassessment registration windows. Returns `422` when start and end are the same instant (`… must not be the same`) or when start is after end (`… must be before …`). Idempotency keys are stored under `/organization-terms` — the same key replays identically when using the `/terms` alias path. Scoped to your integration's institution via Basic Auth credentials.

`POST /organization-terms`

**Request body** (`application/json`, required)

- `name` (string, required)
- `code` (string) — Optional term code. Whitespace-only values are stored as null.
- `termStart` (string<date-time>, required) — Term start date. Must include a timezone offset (\`Z\` or \`±HH:MM\`); values without offset return 422. Must be strictly before \`termEnd\`. If equal to \`termEnd\`, the API returns \`422\` with field error \`termStart and termEnd must not be the same\`.
- `termEnd` (string<date-time>, required) — Term end date. Must include a timezone offset (\`Z\` or \`±HH:MM\`); values without offset return 422. Must be strictly after \`termStart\`. If equal to \`termStart\`, the API returns \`422\` with field error \`termStart and termEnd must not be the same\`.
- `electionStart` (string<date-time>) — Must include a timezone offset (\`Z\` or \`±HH:MM\`).
- `electionEnd` (string<date-time>) — Must include a timezone offset (\`Z\` or \`±HH:MM\`).
- `reassessmentRegistrationStart` (string<date-time>) — Must include a timezone offset (\`Z\` or \`±HH:MM\`).
- `reassessmentRegistrationEnd` (string<date-time>) — Must include a timezone offset (\`Z\` or \`±HH:MM\`).
