LUSID_by_Finbourne

C# SDK for the FINBOURNE Horizon API

Contents

Summary

This is the C# SDK for the FINBOURNE Horizon API, part of the LUSID by FINBOURNE platform. To use it you'll need a LUSID account - sign up for free at lusid.com.

For more details on other applications in the LUSID platform, see Understanding all the applications in the LUSID platform.

This sdk supports Production, Early Access, Beta and Experimental API endpoints. For more details on API endpoint categories, see What is the LUSID feature release lifecycle. To find out which category an API endpoint falls into, see the swagger page.

This code is automatically generated by the OpenAPI Generator project.

Versions

  • API version: 0.1.1048
  • SDK version: 2.0.0

Requirements

  • net6.0+

Installation

The NuGet package for the FINBOURNE Horizon API SDK can installed from https://www.nuget.org/packages/Finbourne.Horizon.Sdk using the following

$ dotnet add package Finbourne.Horizon.Sdk

Getting Started

You'll need to provide some configuration to connect to the FINBOURNE Horizon API - see the articles about short-lived access tokens and a long-lived Personal Access Token. This configuration can be provided using a secrets file or environment variables.

For some configuration it is also possible to override the global configuration at the ApiFactory level, or at the request level. For the set of configuration which can be overridden, please see ConfigurationOptions. For a code illustration of this configuration being overridden, please see the example.

Environment variables

Required for a short-lived access token

FBN_TOKEN_URL
FBN_HORIZON_URL
FBN_USERNAME
FBN_PASSWORD
FBN_CLIENT_ID
FBN_CLIENT_SECRET

Required for a long-lived access token

FBN_HORIZON_URL
FBN_ACCESS_TOKEN

You can send your requests to the FINBOURNE Horizon API via a proxy, by setting FBN_PROXY_ADDRESS. If your proxy has basic auth enabled, you must also set FBN_PROXY_USERNAME and FBN_PROXY_PASSWORD.

Other optional configuration

# the sdk client timeout in milliseconds, the default is 1800000 (30 minutes)
# values must be between 1 and 2147483647
# please note - the chances of seeing a network issue increases with the duration of the request
# for this reason, rather than increasing the timeout, it will be more reliable to use an alternate polling style endpoint where these exist
FBN_TIMEOUT_MS
# the retries when being rate limited, the default is 2
FBN_RATE_LIMIT_RETRIES

Secrets file

The secrets file must be in the current working directory. By default the SDK looks for a secrets file called secrets.json

Required for a short-lived access token

{
    "api":
    {
        "tokenUrl":"<your-token-url>",
        "horizonUrl":"https://<your-domain>.lusid.com/horizon",
        "username":"<your-username>",
        "password":"<your-password>",
        "clientId":"<your-client-id>",
        "clientSecret":"<your-client-secret>"
    }
}

Required for a long-lived access token

{
    "api":
    {
        "horizonUrl":"https://<your-domain>.lusid.com/horizon",
        "accessToken":"<your-access-token>"
    }
}

You can send your requests to the FINBOURNE Horizon API via a proxy, by adding a proxy section. If your proxy has basic auth enabled, you must also supply a username and password in this section.

{
    "api":
    {
        "horizonUrl":"https://<your-domain>.lusid.com/horizon",
        "accessToken":"<your-access-token>"
    },
    "proxy":
    {
        "address":"<your-proxy-address>",
        "username":"<your-proxy-username>",
        "password":"<your-proxy-password>"
    }
}

Other optional configuration

{
    "api": 
    {
        // the sdk client timeout in milliseconds, the default is 1800000 (30 minutes)
        // values must be between 1 and 2147483647
        // please note - the chances of seeing a network issue increases with the duration of the request
        // for this reason, rather than increasing the timeout, it will be more reliable to use an alternate polling style endpoint where these exist
        "timeoutMs":"<timeout-in-ms>",
        // the retries when being rate limited, the default is 2
        "rateLimitRetries":<retries-when-being-rate-limited>
    }
}
