Changelog

Every change to the Trimline API, newest first. Breaking changes are always released under a new version and announced by email to everyone with a live key.

2026-11-01

API version 2026-11-01. This is the first version we’re documenting publicly for beta customers.

• Added GET /v1/savings/summary for period totals broken down by lever.
• Added rationale and expires_at to drafts.
• Added draft.expiring and negotiation.call_requested events.
• Zero retention: document files are no longer stored. GET /v1/documents/:id/file is removed, and documents now carry a source_url. Message bodies are fetched live from your mailbox.
• Breaking: money fields are now objects with amount and currency instead of bare integers in cents. Keys pinned to 2026-09-15 keep the old shape until January 31, 2027.
• Breaking: approved_by is now required on POST /v1/drafts/:id/approve.

2026-10-14

• Added the ramp and stripe providers to connections, in beta.
• Added confidence and verified to contracts, plus the contract.needs_review event.
• Sandbox: added request_call and no_reply outcomes to simulate_reply.

2026-09-15

API version 2026-09-15. First versioned API, built alongside the MVP and used internally on real renewals.

• Vendors, contracts, renewals, negotiations, drafts and savings endpoints.
• Webhook endpoints with signed payloads and automatic retries.
• Sandbox environment with seeded data and test helpers.

2026-08-24

• Proof-of-concept extraction service: reads invoices and renewal notices and returns vendors, prices and notice periods. Internal only.
