Docs state: “You can pass custom data to the conversation via the startChat method.”
const chat = await guestApi.startChat({
customAttributes: {
crmId: "CUST-12345"
}
});
Getting 200 OK. But the crmId isn’t showing up in the webhook payload or the platform UI. Is there a specific schema requirement for customAttributes? Or does the Web Messaging Guest API strip unknown keys? Checked the API reference again, nothing mentions validation errors for custom fields.
