Why Build on SahlSign's API?
If you're building a SaaS product, fintech app, or enterprise tool in the GCC — and your users need to sign documents — you have three options:
- DocuSign API — $8/envelope, data in US, no Arabic templates
- Build your own — 12-18 months of PKI engineering
- SahlSign API — $0.70/document at volume, GCC data residency, Arabic-first
SahlSign's REST API gives you everything you need to embed legally binding signatures into your product, with data that never leaves the GCC.
Core API Capabilities
Document Management
POST /v1/documents — Upload + create document
GET /v1/documents — List documents (paginated)
GET /v1/documents/:id — Get document details
DELETE /v1/documents/:id — Void/cancel document
POST /v1/documents/:id/send — Send for signing
Template-Based Signing
POST /v1/templates/:id/send — Create doc from template + send
Pre-configure your field layout, signer roles, and default settings. Then fire a single API call to create a document from template and send it for signing. Perfect for automated onboarding flows.
Webhooks
POST /v1/webhooks — Register endpoint
Get notified in real-time when documents are signed, viewed, declined, or expired. HMAC-SHA256 signed payloads with replay protection.
Events: document.sent, document.viewed, document.signed, document.completed, document.declined, document.expired
What Makes This Different
GCC Data Residency
Every API call processes and stores data in AWS Bahrain (me-south-1). If your customers operate under PDPPL, Saudi PDPL, or UAE data protection laws — SahlSign is compliant by default.
Arabic-First Templates
Create templates with Arabic field labels, RTL layout, and bilingual certificates. No other signing API offers this natively.
Competitive Pricing
| Volume | SahlSign | DocuSign | |--------|----------|----------| | 1-100 docs/month | $1.50/doc | $8/envelope | | 101-500 docs/month | $1.00/doc | $5/envelope | | 501-2000 docs/month | $0.70/doc | Custom |
At 500 documents/month, that's $500 vs. $2,500 — an 80% cost reduction.
