+# Go API client for cactus-plugin-htlc-coordinator-besu
+
+Can exchange assets between networks
+
+## Overview
+This API client was generated by the [OpenAPI Generator](https://openapi-generator.tech) project.  By using the [OpenAPI-spec](https://www.openapis.org/) from a remote server, you can easily generate an API client.
+
+- API version: 2.0.0-rc.2
+- Package version: 1.0.0
+- Build package: org.openapitools.codegen.languages.GoClientCodegen
+
+## Installation
+
+Install the following dependencies:
+
+```shell
+go get github.com/stretchr/testify/assert
+go get golang.org/x/net/context
+```
+
+Put the package under your project folder and add the following in import:
+
+```golang
+import cactus-plugin-htlc-coordinator-besu "github.com/hyperledger/cactus-plugin-htlc-coordinator-besu/src/main/go/generated/openapi/go-client"
+```
+
+To use a proxy, set the environment variable `HTTP_PROXY`:
+
+```golang
+os.Setenv("HTTP_PROXY", "http://proxy_name:proxy_port")
+```
+
+## Configuration of Server URL
+
+Default configuration comes with `Servers` field that contains server objects as defined in the OpenAPI specification.
+
+### Select Server Configuration
+
+For using other server than the one defined on index 0 set context value `sw.ContextServerIndex` of type `int`.
+
+```golang
+ctx := context.WithValue(context.Background(), cactus-plugin-htlc-coordinator-besu.ContextServerIndex, 1)
+```
+
+### Templated Server URL
+
+Templated server URL is formatted using default variables from configuration or from context value `sw.ContextServerVariables` of type `map[string]string`.
+
+```golang
+ctx := context.WithValue(context.Background(), cactus-plugin-htlc-coordinator-besu.ContextServerVariables, map[string]string{
+	"basePath": "v2",
+})
+```
+
+Note, enum values are always validated and all unused variables are silently ignored.
+
+### URLs Configuration per Operation
+
+Each operation can use different server URL defined using `OperationServers` map in the `Configuration`.
+An operation is uniquely identified by `"{classname}Service.{nickname}"` string.
+Similar rules for overriding default operation server index and variables applies by using `sw.ContextOperationServerIndices` and `sw.ContextOperationServerVariables` context maps.
+
+```golang
+ctx := context.WithValue(context.Background(), cactus-plugin-htlc-coordinator-besu.ContextOperationServerIndices, map[string]int{
+	"{classname}Service.{nickname}": 2,
+})
+ctx = context.WithValue(context.Background(), cactus-plugin-htlc-coordinator-besu.ContextOperationServerVariables, map[string]map[string]string{
+	"{classname}Service.{nickname}": {
+		"port": "8443",
+	},
+})
+```

+## Documentation For Authorization
+
+Endpoints do not require authorization.
+
+
+## Documentation for Utility Methods
+
+Due to the fact that model structure members are all pointers, this package contains
+a number of utility functions to easily obtain pointers to values of basic types.
+Each of these functions takes a value of the given basic type and returns a pointer to it:
+
+* `PtrBool`
+* `PtrInt`
+* `PtrInt32`
+* `PtrInt64`
+* `PtrFloat`
+* `PtrFloat32`
+* `PtrFloat64`
+* `PtrString`
+* `PtrTime`
