The Partner API lets you offer company formation and services under your own brand, and track every order programmatically.

Base URL

Test-mode keys (clmt_test_) run against a sandbox that creates nothing real. Live-mode keys (clmt_live_) run against real companies and billing.

Filtering and expanding

Understand the platform

How it fits together

The objects, the modes, and the one rule behind every design choice.

Company lifecycle

Statuses, stages, identity documents, and the events at each step.

Requirements

Documents, forms, and the asks your client answers without a key.

Service orders

Ordering, fulfilment steps, recurring services, the form standard.

Files

Reading deliverables back, proxied through the API.

Whitelabel

Your customer never hears from Clemta. What you receive instead.

Webhooks

Every event, delivered in order, signed per Standard Webhooks.

Conventions

  • Responses are JSON. Errors follow a single envelope with a machine-readable code. See Errors.
  • Limits are published on every response. See Rate Limiting.
  • Every object names its own type in an object field, so it stays identifiable when nested or delivered in an event.
