Reading Attachments through API

By | May 13, 2021

Attachments are useful in maintaining a track of any supportive documents added to any sale, purchase or journal entry transactions. Supporting information files/images can be attached for quotes, invoices, credit notes, payments, bills, journal entries.
For instance, one can attach a receipt, brochure, commodity images, or any such transaction documents that might prove useful to the customers or vendors.

To find details of a referenced attachment ID from GL batch, AP bill, etc., we can use Sage Intacct Web Services. They are the systematic way of retrieving data through API. These XML-based API calls are convenient means to read the complete data of any object in Intacct. We can apply queries and filter it according to our needs.

We can use the <get_list object=”supdoc”> function to read the object supdoc. Attachment IDs are stored as SUPDOCIDs in GLBatch, AP Bill, Invoice objects as shown below.


For extracting any particular attachment data as base64 encoded string, we can query in the following way. The SUPDOCID(Attachment1) that we supplied in the below query can be retrieved by firing a read query on the desired object. The value of the field <SUPDOCID> is to be fetched from response.


The function returns all the details like name, type, base64 of the attachment and the supporting document creation details. Below is the response snippet after executing the above query:


This is how we can fetch the details of any attachment through web services so easily. Once we get the base64 and the attachment type, we can further carry out actions that feeds it to some external program if required.
