# GetAttachment


Provides a pre-signed URL for download of a completed attachment. This is an asynchronous API for use with active contacts.

For security recommendations, see [Amazon Connect Chat security best practices](https://docs.aws.amazon.com/connect/latest/adminguide/security-best-practices.html#bp-security-chat). 

**Note**  
The participant role `CUSTOM_BOT` is not permitted to access attachments customers may upload. An `AccessDeniedException` can indicate that the participant may be a CUSTOM\$1BOT, and it doesn't have access to attachments.
 `ConnectionToken` is used for invoking this API instead of `ParticipantToken`.

The Amazon Connect Participant Service APIs do not use [Signature Version 4 authentication](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html).
