I’m using the engagements endpoint, and the attachment information to hit the filemanager endpoint for files and getting the file attachments for a given deal. I’ve seen 3 different properties with urls that seems to be for that attached file, but, to my surprise, all those links fail. 2 of them fail with a 404, and one of them fails with a 403. My question is, is there no way I can download those files via API? Or choose to publicly expose them? Also, what is the point of the url properties I mentioned? Thanks ---

Hi, @mathcee. I reponded to [your original post](https://community.hubspot.com/t5/APIs-Integrations/Get-attachments-on-a-company-contact-or-deal/m-p/300053#M28204) a little earlier, but I’m happy to continue the discussion here. Can you confirm that your Hub ID ends with **7645** and then share the following? 1. The ID of a CRM object you are pulling engagements from (contact, company, deal, or ticket). 2. The ID of an engagement on the above object which has file IDs in the `attachments` array you are interested in. 3. The IDs of the attachments you are trying to access. Also, which URL properties are you trying? If you’re using [this endpoint](https://developers.hubspot.com/docs/methods/files/get_files_file_id) and the file is publicly accessible, the `url` field is the one to use. ---

Confirmed. That is indeed the end to my Hub ID. Deal ID: 374693036 Engagement ID: 3815773955 Attachment ID: 19892487693 ---

Hi, @mathcee. Sincere apologies for the delayed response. For some reason, your response was filtered from my inbox. Thank you for sharing that information. I found the file you referenced and replicated the behavior you’ve described. File **19892487693** is `"hidden": true`, which prevents it from being accessed at public file URLs like [https://cdn2.hubspot.net/hubfs/…7645/Your-file.pdf](https://cdn2.hubspot.net/hubfs/3957645/Teste%20de%20novos%20snipptes2-1-1.pdf). Per Derek’s first response to [this Community post](https://community.hubspot.com/t5/APIs-Integrations/What-decides-if-a-COS-file-is-hidden-or-not-If-uploaded-to-CRM/m-p/226917) as well as @SwivelDev’s response to [this other Community post](https://community.hubspot.com/t5/APIs-Integrations/Download-deal-attachement/m-p/272854/thread-id/24778#M24802), files which are uploaded externally directly to a deal or contact will be hidden by default. At this time, it is not possible to change a file from `"hidden": true` to `"hidden": false`, or vice versa, as indicated in [this article](https://developers.hubspot.com/docs/methods/files/post_files). I am sorry if this comes as an unwelcome surprise. One way to prevent files from being hidden is to upload them to HubSpot’s file manager _before_ attaching them to an engagement.
