messengers API documentation

Full documentation

The REST API allows you to receive and send messages through your messengers account. Sign up now

Parameters in GET queries pass query string. Parameters in POST requests — through the JSON-encoded request body. The authorization token is always passed to query string (?token=xxxxxx).

The messengers API is based on the messengers WEB protocol and excludes the ban both when using libraries from mgp25 and the like. Despite this, your account can be banned by anti-spam system messengers after several clicking the "block" button.

POST /group

Creates a group and sends the message to the created group. If the host is iPhone, then the presence of all in the contact list is required.

The group will be added to the queue for sending and sooner or later it will be created, even if the phone is disconnected from the Internet or the authorization is not passed.
