Your routing policy defines how your transactions are routed. You can choose 1 of the 3 different schemes mentioned below for each asset type: - **None**; Defines the profile routing to no destination for that asset type. Incoming transactions to asset types routed to `None` will fail. - **Custom**; Route to an account that you choose. If you remove the account, incoming transactions will fail until you choose another one. - **Default**; Use the routing specified by the network profile the connection is connected to. This scheme is also referred to as "Profile Routing" Default Workspace Presets: - Network Profile Crypto → **Custom** - Network Profile FIAT → **None** - Network Connection Crypto → **Default** - Network Connection FIAT → **Default** Supported asset groups for routing police can be found at `/network_ids/routing_policy_asset_groups` - **Note**: By default, Custom routing scheme uses (`dstId` = `0`, `dstType` = `VAULT`). ## OpenAPI ````yaml https://docs.fireblocks.com/api/v1/swagger.yaml post /network_connections openapi: 3.0.0 info: title: Fireblocks API description: > Fireblocks provides a suite of applications to manage digital asset operations and a complete development platform to build your business on the blockchain. - Visit our website for more information: [Fireblocks Website](https://fireblocks.com) - Visit our developer docs: [Fireblocks DevPortal](https://developers.fireblocks.com) version: 1.6.2 contact: email: developers@fireblocks.com servers: - url: https://api.fireblocks.io/v1 description: Fireblocks Production Environment Base URL - url: https://sandbox-api.fireblocks.io/v1 description: Fireblocks Sandbox Environment Base URL security: [] paths: /network_connections: post: tags: - Network connections summary: Create a new network connection description: > Initiates a new network connection. **Note:** This API call is subject to Flexible Routing Schemes.
