Sending Multiple Attachments: Sending a batch of 100 image attachments through the DirectLine API may impact message delivery and performance. Consider the message size limit (64KB) and any limitations of Azure storage accounts, such as transactions per second and storage capacity.
Attachment URL Expiry Time: The expiry time for attachment URLs provided by DirectLine (Base 64 URLs) depends on your implementation and storage service. You can configure the expiry time when generating the URLs or set up a specific policy for URL expiration.
Data Security: Ensure data security by encrypting sensitive information, transmitting it securely over HTTPS, and following best practices. Refer to Azure's security documentation for guidance on securing DirectLine messages and adhering to compliance requirements.
