Once the process is initiated, you will be provided with the 'status_url' initially. By invoking the 'status_url', you will be able to check the status of the scheduled job. 

Sample Response

Copied{
    "status_url": "https://writer.zoho.com/writer/api/v1/documents/pdf/combine/job/f931a01183b33
}

Job completion status can be checked using the 'status' key. Once the status is changed to 'completed', you will be provided with a 'download_url'. Using which, you can download the combined file as bytes.

Copied{
"status": "completed/inprogress/failed"
"download_link":"https://writer.zoho.com/writer/api/v1/documents/pdf/combine/download/e8447fe5069440a15042f5a92d4f29404e26d9b43cd324d8816e46ba869c45ffa4ea798cc574a41281f257cc0c7a74cb937398933f9307f03e018ac4fb9d19640be41a77fc506a6ff4fef7632f12e6744ef0780637a3bcb047204642170ada40"
