Welcome to the Watheeq developer documentation. Learn how to integrate blockchain documents verification into your applications.
What is Watheeq?
Watheeq is an enterprise-grade platform for issuing and verifying digital credentials using blockchain technology. We provide a secure, immutable ledger for documents that ensures authenticity without exposing sensitive personal data.
Issuance
Create tamper-proof documents anchored to the blockchain.
Verification
Instantly verify validity using Public IDs or QR codes.
How it Works
When you issue a document through our API, the following happens:
1
Data HashingWe generate a cryptographic SHA-256 hash of the document data (subject name, dates, metadata).
2
AnchoringThis hash is batched and submitted to a permissioned blockchain ledger.
3
Proof GenerationWe return a unique publicId and QR code that links to the verification proof.
During verification, we re-hash the presented data and compare it against the immutable record on the blockchain. If they match, the document is valid.
Getting Started
To start issuing documents, you'll need an API key.
