Creating or Updating Connections using the REST API

This document covers the following topics:

Introduction

You can create or update connections, adapter services and listeners, using the REST API.

Start of instruction setTo create a connection, adapter service or listener

  • Send the request to the Integration Server to the following URL:

    http://hostname:port/restv2/wmentirex/createConnection

    Example:

    http://localhost:5555/restv2/wmentirex/createConnection

Start of instruction setTo update a connection, adapter service or listener

  • Send the request to the Integration Server to the following URL:

    http://hostname:port/restv2/wmentirex/updateConnection

    Example:

    http://localhost:5555/restv2/wmentirex/updateConnection

Configuring your Input Parameters

Start of instruction setTo configure your input parameters

  • Use a JSON request document. Parameters valid for all connection types and parameters for specific connection types are described in the sections below.

    Sample JSON file createConnection.json:

Response Codes

The HTTP response is in JSON format and contains two parameters, infos and error.

  • Successful Request
    If a request is successful, infos contains a comma-separated list of objects that were created or updated, and the error parameter is empty. Example: 

    {
  "infos": [
    "Connection rpc:RpcConnection created",
    "Adapter Service rpc:CALC created",
    "Adapter Service rpc:SQUARE created"
  ],
  "error": null
}

    The HTTP response code is 200 (OK).

  • Unsuccessful Request
    If a request is not successful, the infos parameter is empty, and the error parameter contains the reason for the failure. Example: 

    {
  "infos": null,
  "error": "Required parameter connectionName is missing"
}

    The HTTP response code is 500 (internal server error).

  • Invalid Syntax
    If the JSON input file has a syntax error (invalid input), the error parameter contains the reason for the JSON parser failure: 

    {
  "idlSourceBase64": null,
  "error": {
  "$errorDump": "com.fasterxml.jackson.core.JsonParseException:Unexpected character
  (';' (code 59)): was expecting comma to separate Object entries\n at [Source:

...
}

    The HTTP response code is 400 (bad request).

Base64 Resources
