Other documents

Send PDF letters to Ropo using a JSON index file.

Send letters to Ropo as PDF + index JSON.

Use this for customer letters, contracts, reports, and similar documents.

Prerequisites

You need:

• cid + apicode

• a JWT token in Authorization: Bearer <token>

Authentication

Delivery options

You have two common ways to deliver the PDF.

Option A: HTTPS with embedded PDF (base64)

Put the base64-encoded PDF content in:

• image.file

Use this when your payload format supports embedded files.

Option B: Deliver the PDF as a separate file (ZIP)

Deliver the PDF file(s) and the index file in the same ZIP package.

Use this when:

• you cannot embed base64 in JSON

• the PDFs are large

• you want to upload file + data together

Data transfer limits and ZIP uploads

If you use SFTP delivery, the PDF and index must still be in the same ZIP package.

Minimum letter payload

Send one item in datastream.dataset[].
