Documented steps
Immediate delete: DELETE https://console.neon.tech/api/v2/projects/{project_id}/branches/{branch_id} — response includes suspend_compute and delete_timeline operations to poll
Set expiration at creation: POST /projects/{project_id}/branches with the branch object containing "expires_at": "<RFC 3339 timestamp>"
Set/update expiration on an existing branch: PATCH /projects/{project_id}/branches/{branch_id} with {"branch": {"expires_at": "..."}}; clear it with "expires_at": null
A background job deletes expired branches shortly after (not exactly at) the expires_at time
Known gotchas
You cannot delete the default/root branch or a protected branch (remove protection first via PATCH {"branch": {"protected": false}}); attempts fail with 422
Branches with children cannot be deleted — delete child branches first
Branch expiration (expires_at) was gated to Early Access Program participants — it may not be enabled for your account; plain DELETE always works
Deleting a branch also deletes its compute endpoints and all databases/roles on it
expires_at must be RFC 3339 with second precision, e.g. 2026-06-09T18:02:16Z
