Kaizen #45 - Handling Attachments API in Java and Java SDK (Part 2/2)

Kaizen #45 - Handling Attachments API in Java and Java SDK (Part 2/2)

Hello everyone!

Welcome back to yet another post in the Kaizen series. In our last post, we started our discussion about handling the attachments in Java and Java SDK where we discussed listing the attachments and uploading the attachments to a record in Zoho CRM.

This week, we will discuss the other two operations in attachments API.
1. Download an attachment 
2. Delete an attachment.


1. Download an Attachment
To download a file attached to a record.

Request method: GET
Request URL:  {{api-domain}}/crm/v2/{module_api_name}/{record_id}/Attachments/{attachment_id}

Sample URL: {{api-domain}}/crm/v2/Leads/3719520000000659047/attachments/3719520000000992004

Java SDK Code
The Java SDK employs downloadAttachment() method for the operation which primarily requires the record_id(3719520000000659047) and the attachment_id(3719520000000992004) for its successful execution. The attachment_id can be fetched from List Attachments API. 

public void downloadAttachment() throws Exception{
  ZCRMRecord record=ZCRMRecord.getInstance("Leads",3719520000000659047L);
  FileAPIResponse responseIn=record.downloadAttachment(3719520000000992004L);
       String filepath="/Users/srivathsan-8829/Documents";
        File file=new File(filepath+responseIn.getFileName()); 
        System.out.println( "HTTP Status Code:"+responseIn.getStatusCode());
        System.out.println( "File Name:"+responseIn.getFileName());
        InputStream fin = responseIn.getFileAsStream();
        int i=0;    
        while((i=fin.read())!=-1){    
         System.out.print((char)i);    
        }    
    }

Java Code
public void downloadAttachments() throws Exception
 {
  CloseableHttpClient httpclient = HttpClients.createDefault();
     HttpGet httpget = new HttpGet("{{api-domain}}/crm/v2/Leads/3719520000000659047/attachments/3719520000000991001");
     httpget.addHeader("Authorization", "Zoho-oauthtoken 1000.9XXXX.6XXXX");
     System.out.println("Request Type: "+httpget.getMethod());
     HttpResponse httpresponse = httpclient.execute(httpget);
     Scanner sc = new Scanner(httpresponse.getEntity().getContent());
     System.out.println(httpresponse.getStatusLine());
     while(sc.hasNext()) {
          System.out.println(sc.nextLine());
     }
}

Sample Response:


2. Delete an Attachment
To delete a file attached to a record.

​Request method: DELETE
Request URL:  {{api-domain}}/crm/v2/{module_api_name}/{record_id}/Attachments/{attachment_id}

Sample URL:  {{api-domain}}/crm/v2/Leads/3719520000000659047/attachments/3719520000000981001

Java SDK Code
Similar to download attachment operation, delete attachment requires the record_id and the attachment_id as the pre-requisites. The operation is performed with the assistance from deleteAttachment() method. The attachment_id can be fetched from List Attachments API. 

public void deleteAttachment() throws Exception{
  ZCRMRecord record=ZCRMRecord.getInstance("Leads",3719520000000659047L);
  APIResponse responseIn=record.deleteAttachment(3719520000000981001L);
  System.out.println( "Status:"+ responseIn.getMessage());
        System.out.println( "Message:"+ responseIn.getStatus());
        System.out.println("http code"+ responseIn.getStatusCode());
        System.out.println( " Code:"+responseIn.getResponseJSON().toString());
 }

Java Code
public void deleteAttachments() throws Exception
 {
  CloseableHttpClient httpclient = HttpClients.createDefault();
     HttpDelete httpdelete = new HttpDelete("{{api-domain}}/crm/v2/Leads/3719520000000659047/attachments/3719520000000981001");
     httpdelete.addHeader("Authorization", "Zoho-oauthtoken 1000.9XXXX.6XXXX");
     System.out.println("Request Type: "+httpdelete.getMethod());
     HttpResponse httpresponse = httpclient.execute(httpdelete);
     Scanner sc = new Scanner(httpresponse.getEntity().getContent());
     System.out.println(httpresponse.getStatusLine());
     while(sc.hasNext()) {
          System.out.println(sc.nextLine());
     }
 }

Sample Response
{
    "data": [
        {
            "code": "SUCCESS",
            "details": {
                "id": "3719520000000981001"
            },
            "message": "record deleted",
            "status": "success"
        }
    ]
}
