Create an emoji message

Use an emoji message for an entry in an application-defined emoji pack. The SDK neither downloads emoji assets nor interprets the application protocol, so sending and receiving clients must agree on the meaning of the index and extension data.

const { data: message } = await openimsdk.createFaceMessage({
  index: 12,
  data: JSON.stringify({ pack: 'default' }),
});

index is the agreed emoji index. data is the complete extension string and can contain the emoji-pack identifier, version, and other required metadata. Do not store sensitive information in data, and provide a placeholder image or text for an unknown pack or index.

When the Promise resolves, data is a pending MessageItem. Creating it neither uploads emoji assets nor sends the message. Next, use sendMessage() as described in Send a message.
