Get invoice attachment with RestAPI

[murray99]

Look at application\Espo\EntryPoints\Download.php as an example of serving attachments. This allows download for authenticated users, but depending on how you expect your users to access the invoice (and the level of security you expect) you could remove authentication and add some sort of security key.

This issue is resolved.

I'm using N8N to upload invoices every day to dropbox so my accountant can access them.

The general flow is

Iterate invoices made today
https://crm.domain.com/api/v1/Invoice?where[0][type]=equals&where[0][field]=dateInvoiced&where[0][value]=2023-03-19

Get associated email with each item
https://crm.domain.com/api/v1/Email?where[0][type]=equals&where[0][field]=accountId&where[0][value]=XYZ&where[0][type]=equals&where[0][field]=name&where[0][value]=Invoice XYZ

Get the specific email detals

https://crm.domain.com/api/v1/Email/XYZ

Get the attachment

https://crm.domain.com/api/v1/Attachment/file/XYZ

Hi,

Is it possible to fetch the attachment of an invoice?

I run the following get command to get a list of todays invoices:
https://crm.domain.com/api/v1/Invoice?where[0][type]=equals&where[0][field]=dateInvoiced&where[0][value]={{ $json.today }}

What I want to do then is to iterate and go through all the invoices and get it's attachment or attachment ID.
