# Version 1.1.0 - REST API Expansion

Released on June 11, 2026

Spark CRM v1.1.0 delivers a major expansion of the REST API, giving external systems and integrations full programmatic control over the platform — configuring campaigns, products, payment routing, auto responders, affiliates and subscriptions without ever touching the dashboard.

## What's New

### Campaign Configuration
Build and manage entire campaigns through the API:
- **Campaigns** — create, retrieve and update campaigns
- **Offers & Upsells** — full CRUD for the products, pricing and subscription configuration behind each campaign
- **Affiliates** — assign and unassign affiliates to campaigns with payout rules
- **Auto Responders** — attach and manage per-campaign automated email responders

### Products
Create, retrieve and update your product catalog programmatically — ideal for syncing inventory and catalog data from external systems.

### Payment Routing
Take full control of payment orchestration via the API:
- **Payment Routers** — create and update routers with their algorithm and failover settings
- **Gateways** — attach, update and detach gateways on a router, with priority, weight and processing limits
- **Routing Rules** — define conditional routing logic with priorities, target gateways and fallback behavior

### Decline Salvage Profiles
Configure retry behavior and decline-code handling through the API to maximize recovery on failed payments.

### Affiliates
Full lifecycle management of affiliates — profiles, tracking IDs, throttling and status — directly via the REST API.

### Subscriptions
Complete programmatic control of recurring billing:
- **List & filter** subscriptions by status and other factors
- **Create** administrative subscription records from a customer and billing configuration
- **Update** the next billing date or billing cycle
- **Cancel, pause and restart** subscriptions

## Bug Fixes

- Fixed array-based validation rules that broke PATCH (partial update) requests on several REST endpoints.
- Hardened REST API validation to prevent database constraint violations (NOT NULL and unique) on create and update.

## Breaking Changes

None - this release is fully backward compatible. All new endpoints are additive and existing API behavior is unchanged.

## Authentication & Permissions

Every new endpoint is protected by granular API token permissions (for example `api:subscriptions.create`, `api:payment_routers.update`). All requests are scoped to the authenticated account, and resources belonging to other accounts return a `404 Not Found`.
