Description

Message is any data sent as part of the server-client interaction. Any message MUST have a type high level property with the message type (see Types).

Transport

As a data transmission channel, HTTP or sockets can be used. See Core documentation for details.

When using the HTTP protocol, only action, response, error messages can be used.

Types

There are several types of messages for communication. The main types of messages: action, response and error. These types of messages can be sent and received via any transport.

Action

The Action message is a message, which is a request to perform some action and return its results as a Response. Action can be sent only from a client side.

Any action message MUST have a name and a parameters properties. The name property contains a name of action (e.g. auth.sendCode). The parameters property is a list of parameters for action.

Also, Action message can have these optional properties:

• id property: a random identifier for the Action message which MUST be returned in the Response message if the identifier was sent
• token property: access token to this action (you can pass the token in other ways)

Example:

{
    "type": "action",
    "name": "auth.sendCode",
    "parameters": {
        "phone": "[phone]",
        "requestId": "d0f2f571-d07d-4e1d-bdf6-e3470efe9ac5",
        "code": "012345"
    }
}

Response

The Response message is a message returned as the result of the Action if the action completed successfully. A message of this type MUST have a content property, that contains the results of action. Response can be sent only by the Core.

Also, Response message can have these optional properties:

• id property: an identifier from the Action message if the identifier was sent

Example:

{
    "type": "response",
    "content": {
        "method": "sms",
        "requestId": "b4b12d26-8fd6-4d9f-aa2c-0e56ced951be",
        "expiredAt": 1587075673
    }
}

Error

The Error message is the message returned if an error occurred while performing an action. The error message MUST have a code and message properties. The code property is a number code of error. The message property is a short description about error. A complete list of errors that may be thrown is available here. Error can be sent only by the Core.

Example:

{
    "type": "error",
    "code": 51,
    "message": "One of the passed parameters is invalid."
}
