AdapterDian for developers

Guides and API reference for issuing, receiving and reporting DIAN electronic documents from your application with AdapterDian.

AdapterDian gives your application one REST API for Colombia’s electronic tax cycle: sales invoices and their notes, support documents, received documents with RADIAN events, and electronic payroll. The contract is provider-neutral: you send business concepts and the adapter translates them to the technology provider underneath.

Start here

1. Quickstart: issue a sales invoice and check its status.
2. Authentication: API keys, permissions and expiry.
3. Errors: the RFC 7807 format and what to do with each code.

Guides

• Idempotency: why every issuing POST requires Idempotency-Key.
• Document lifecycle: statuses, warnings, downloads and discarding.
• Numbering ranges: which numbering_prefix to declare.
• Received documents and RADIAN: the inbox and the three-business-day deadline.

Reference

The API reference is generated from the live OpenAPI document (/openapi.json) and lets you try each operation with your own API key.
