Posted on by Devender Adlakha

I am using Dynamic 365 Web API for creating a record using Mobile App. Everything is working fine, but I am stuck on uploading a file using the web API. I have gone through this link https://docs.microsoft.com/en-us/powerapps/developer/data-platform/file-attributes. and tried using the method mentioned, but still, it is not working.

Please help!!

RE: How to attach file file while creating a record in Dynamic 365 using Web API

Hi Charan Raju

I am using POSTMAN and sending a PATCH request on

yourdomain.api.crm8.dynamics.com/.../s36000_ic

with the following headers{

x-ms-file-name:ic.png,

x-ms-transfer-mode:chunked

}.

after this request is triggered I get a location variable from the response header and again I am making a PATCH request on this:

yourdomain.api.crm8.dynamics.com/.../s36000_ic

with the following headers

{

Content-Range : bytes 0-33554431/*

Content-Type : application/octet-stream

x-ms-file-name : ic.png

Content-Length : 10737456

}

but still, i am getting an error

Hi Charan Raju C R

I am storing data at 2 Places, first, I am making a post request on to my server and uploading the image into the database by converting it into the base64 format.

now when my base64 string is stored in the database I am using the dynamics 365 web API for file upload.

my backend API's are created in laravel and from laravel I am using HTTP::Patch Request with bearer token.

Hi Devender,

How are you uploading the file? Using HTML webresource to browse and select the file for uploading from mobile device?
