Callback Response:

Option 1: oneveryrecord

If the 'invoke_period' key inside the 'webhook' parameter is set to "oneveryrecord", we will process each record individually, generate a merged PDF for each, and trigger the webhook callback immediately with the respective PDF.

Note: For this flow, only the "separatedoc" option is supported for the 'merge_to' parameter, as each record is processed and sent separately. The "singledoc" option is not applicable in this case.

Copieddata:{
	"attachment_name": "<file name>.pdf", 
	"fieldid1": "field value",
	"fieldid2": "field value"
	}

file: <Multipart file>

Option 2: oncomplete

If the 'invoke_period' key under the 'webhook' parameter is set to "oncomplete", we will initiate PDF generation for all records in parallel and trigger the webhook callback only after the PDF generation for all records is complete.

Note: This flow supports the following 'merge_to' options:

separatedoc – A separate PDF is generated for each record and all files are sent in a single webhook callback. Each file can be identified using the 'attachment_name' field in the response data.
Important: For a large number of input records (more than 10), the response body size can become large. In such cases, we split the output into batches of 10 records and invoke the webhook callback multiple times in a loop until all records are processed.
singledoc – All merged PDFs are combined into a single PDF file, which is then sent via a single webhook callback.

Copieddata:[
		 {
		"attachment_name": "<file name1>.pdf", 
		"fieldid1": "field value",
		"fieldid2": "field value"
		},
		{
		"attachment_name": "<file name2>.pdf", 
		"fieldid1": "field value",
		"fieldid2": "field value"
		}...
	]

file: <Multipart file - multiple or single PDF file based on merge_to >
