How to add attachment to Business Central

Posted on by 130

Hi, 

I am trying to implement adding attachments to Business Central via Oauth

Maybe I am doing something wrong, please, look at my steps.

1)POST to create an Incoming Document record entry /attachment

Image

where _connectionDynamicsBusinessCentralOptions.Scope value is  "api.businesscentral.dynamics.com/.default"

URL : /v2.0/fc586214-b714-4bc4-8ff8-2e13a1a007cd/Sandbox/api/v2.0/companies(51fafb6c-c141-ec11-bb7e-000d3abb14eb)/salesOrders

BODY : {"externalDocumentNumber":"finally","currencyCode":"EUR","customerNumber":"10000","orderDate":"2023-08-05"}

The request is successful and data already generated in dynamics' system

2) Step 2 I retrieved Parent Id

3) Step 3

I am trying to create attachment

URL is  /v2.0/fc586214-b714-4bc4-8ff8-2e13a1a007cd/Sandbox/api/v2.0/companies(51fafb6c-c141-ec11-bb7e-000d3abb14eb)/attachments

BODY is  {"parentId":"5157829e-b5bd-ed11-9a88-002248d5380a","fileName":"123.txt"}

Request is successful and I get Id for attachment 

Image

4)Step 4

Everything is ready for PATCH method  via /companies(CompanyId)/attachments(IncomingDocumentId)/attachmentContent

I am using the following code

Image

In this part user and password are client id and client secret for Oauth authentication

Image

 BaseAddress is "api.businesscentral.dynamics.com/.default"

Image

Authorization parameter is Bearer  - oauth token 

Image

URl is following

And I get this

    Hello,

    We currently do not have dedicated Dev support via the Dynamics 365 Business Central forums, but I wanted to provide you some additional resources to assist. If you need assistance with debugging or coding I would recommend discussing this on one of our communities.

    www.yammer.com/dynamicsnavdev

    www.dynamicsuser.net/.../14

    I will open this up to the community in case they have something to add.

    Thanks.
