Chat and correspondent Id#

В Green API supports two types of chats - personal chat and group chat. A personal chat is used to send personal messages to the recipient. Group chat is used to organize communication of several participants in a group. To work with group chats, the Green API provides relevant methods. Before sending a message to a personal or group chat, you need to get a chat Id.

Correspondent Id#

Correspondent Id is used to identify the recipient in outgoing messages and to identify the sender in incoming messages, as well as in any other API methods that require a correspondent to be identified. The format of the correspondent Id is the same as the Personal chat Id.

Personal chat#

The format of the personal chat Id is formed according to the template 00000000000@c.us, where it is required to use the recipient's phone number instead of zeros00000000000. The telephone number must be entered in full, with the country code and without spaces. Example:

11001234567@c.us

Group chat#

Group chat Id presents a string of XXXXXXXXXX-XXXXXXXXXX@g.us or XXXXXXXXXXXXXXXXX@g.us form. Example:

11001234567-1581234048@g.us
120363043968066561@g.us

Group chat Id may be received by various Green API methods, for example:

• Create group
• Get outgoing messages journal
• Get incoming messages journal
• Incoming message: Text
• etc.

Important

You are NOT required to generate Group chat Id manually. It is generated automatically by the system and returned by various Green API methods.
