​
Description

Sends the read ACK for a specific message, the visible effect for the sender is the “blue check”. To mark the entire chat at once, use markChatRead.
In groups, the sender field (JID of the message author) is required. In 1-to-1 conversations it is optional and may be omitted.

​
Examples

​
DM

In a 1-to-1 conversation, just messageId and the contact’s number are needed. sender can be skipped, the server infers the author from the chat JID. 
curl -X POST "https://ryzeapi.cloud/api/chat/markRead/$Instance_Name" \
  -H "token: $Token_Instance" \
  -H "Content-Type: application/json" \
  -d '{
    "messageId": "3EB08FCF27E532F1B0F5",
    "number":    "5511999999999"
  }'

​
Group (with sender)

In a group (@g.us), the sender field with the message author’s JID is required, without it WhatsApp cannot route the read ACK correctly. 
curl -X POST "https://ryzeapi.cloud/api/chat/markRead/$Instance_Name" \
  -H "token: $Token_Instance" \
  -H "Content-Type: application/json" \
  -d '{
    "messageId": "3EB08FCF27E532F1B0F5",
    "number":    "120363123456789@g.us",
    "sender":    "5511999999999@s.whatsapp.net"
  }'

​
Success response

The response echoes the message_id that was marked and the resolved chat_jid. Useful to audit which messages were marked as read, especially in automated flows that confirm receipt after processing the message.
