Hi @Akram Baig Mirza Mohamad,

Per my test, you can use the following rest api to get the content of a file. But this api can only get the files in Shared Document.

http://mysite.sharepoint.com/<site_name>/_api/web/getfilebyserverrelativeurl('<url>)/$value?binaryStringResponseBody=true

For the files in other library I will recommend you to use graph api driveitem-get-content

GET /sites/{siteId}/drive/items/{item-id}/content

Hi @Akram Baig Mirza Mohamad,

The graph api can be used in js, you can take following code

const options = { authProvider, }; const client = Client.init(options); let stream = await client.api('/me/drive/items/{item-id}/content') .get();

I have tried below code to get the content of file and preview using iframe tag. but the content is getting downloaded instead of preview.

i have used the api

"https:{site-url}/_api/Web/GetFileByServerRelativeUrl('/sites/LeadInfo/Leads/Account/Lightning Web Components Specialist Superbadge/20230710T054723_GoogleFormAPIDetails.pdf')/$value"

.then(response => { response.blob(); }) .then(blob => { const blobUrl = URL.createObjectURL(blob); this.iframeSrc = blobUrl; // window.open(blob); }) .catch(error => { console.error('Error fetching file content:', error); });
