It takes quite a long time to upload an image. How do I upload it faster?
You can upload your image to the Facebook server or WhatsApp Client by using the Attachment ID or Media ID.
Upload the image by selecting Attachment ID Uploader on the top right corner of the bot builder.
Upload the image to the designated channel and can obtain an "Attachment ID" / "Media ID".
Apply the IDs to your image type response in your tree node.
Please refer to Attachment ID Uploader for more details.
