Workflow

Use the following URL: https://api.avangate.com/channel-manager/2.1/rpc /
Authenticate using the login method and create a session (connection).
Set partner
Throughout the lifetime of the session (max 10 minutes), you can invoke all 2Checkout API methods. To invoke methods you need to send a request to 2Checkout. Read more on the request object below.
The 2Checkout system provides responses to all requests. Read more on the response object below.

Response

Whenever you call an API method, 2Checkout replies with a response. The response is a single object serialized using JSON.

There are two types of response, with the properties detailed below.

{
"id" : <int identifier>,
"jsonrpc" : 2.0,
"response" : {<return object>}
}

Valid response object
Properties	Type/Description
jsonrpc	Required (string)
	JSON-RPC protocol version. Must be 2.0.
id	Required (int)
	Mandatory identifier that you control, used to identify the request and the response. Use only integer values.
response	Required (object)
	Provided on success (is not included if there was an error invoking the method). Actual value depends on the method invoked.

{
"id" : <int identifier>,
"jsonrpc" : 2.0,
"error" : { "code" : <int error code>, "message" : "<error message>"}
}

Invalid response object
Properties	Type/Description
jsonrpc	Required (string)
	JSON-RPC protocol version. Must be 2.0.
id	Required (int)
	Mandatory identifier that you control, used to identify the request and the response. Use only integer values.
error	Required (object)
	Code - Integer identifying the error. Message - Error description (string).

Calling API methods involves sending an API request to Avangate. The request object is detailed below.

{ 
"jsonrpc" : 2.0, 
"id" : <int identifier>, 
"method" : "<methodName>", 
"params" : [<parameters array>] 
}

Request object
Properties	Type/Description
jsonrpc	Required (string)
	JSON-RPC protocol version. Must be 2.0.
id	Required (int)
	Mandatory identifier that you control, used to identify the request and the response. Use only integer values.
method	Required (string)
	The name of the method invoked. Case sensitive.
params	Optional (object)
	An object/structure containing the parameters valid for invoking the method used. Parameters structure: Parameters included into the RPC call need to be provided by-position using an Array. (structured value) by-position: include all parameters into an Array. The values must be in order expected by Avangate. At this point we don't support by-name parameters.
