With Sinch Chat, it's possible to provide your conversation metadata. Here's an example:
SinchSdk.Chat.setConversationMetadata({
once: {
'userName': 'John'
},
eachMessage: {
'phoneNumber': '123 123 123',
'website': 'www.example.com'
}
});The metadata stored as once will be sent only once at the beginning of the conversation, while eachMessage metadata will be attached to each message.
