Hi,

I'm trying to understand how to upload file (as attachment) to D365FO via OData API. Is it possible?
I saw quite a lot questions about this but didn't find an answer.

Just to be clear, an example:
There is a Purchase Order in the D365FO. I want to add attachment to it via API. How should I do it? Is there any code examples?

If it is not possible to do via OData, is there any other ways for external services (for example, simple console application) to do it?

Also, I saw info about Recurring Integration. Not sure that is what I want.

Thanks!

Hi Androsik Vladimir,

How do you want to upload the attachment, you could use file upload control to upload attachment , please check the FileUploadTemporaryStorageStrategy.uploadFile() method, it will upload files to the temporary blob storage and you could use FileUploadTemporaryStorageResult class to get a download url.

Hi Will Wi,

Blob storage is ok. But is it possible to do via REST API? Without using AX framework?

Just to be clear: Let's say, I want to create new Purchase Order.

So, I'll send request like:

Method: POST

URL: https://{baseUrl}/data/PurchaseOrderHeaders

Body:

{

// some data

}

If I entered all the data correctly, the order will be created.

Can I do something similar to add an attachment to this order?

I saw this post: https://community.dynamics.com/365/financeandoperations/f/dynamics-365-for-finance-and-operations-forum/373447/uploading-attachment-to-current-record-in-dynamics-f-o-with-the-use-of-odataultility-library-c
There author is trying to do something very-very similar to what I want. But, honestly, I can't understand completely how to do it for Purchase Orders.

Yes, after you have created the header then use the following

URL: https://{baseUrl}/data/PurchaseOrderHeaderDocumentAttachments

body:

{ "FileName": "VelradLogo", "dataAreaId": "vel", "DocumentAttachmentTypeCode": "File", "FileType": "png", "PurchaseOrderNumber": "VEL-000021", "Notes": "Velrad Logo", "Attachment": " -- base64 of attachment goes here --- " }

PurchaseOrderHeaders and PurchaseOrderHeaderDocumentAttachments work for Purchase Order.

How about Purchase Requisition and Purchase Agreement?

PurchaseRequisitionHeaders and PurchaseAgreements are available, but I cannot find the attachment APIs for them.
