Porichoy API Bangladesh NID Verification: The Ultimate Integration Guide for 2026
A comprehensive deep-dive into Bangladesh Election Commission's Porichoy API — covering Basic NID verification, Autofill NID, and Face Match biometric endpoints. Complete with ERP benchmarks (SAP, Oracle, Dynamics 365, Odoo), operational troubleshooting for Developers, Architects, DBAs, and MIS teams, plus production-ready code examples in 5+ languages.
1. What Is the Porichoy API? – A Deep Introduction
The Porichoy API is the official cloud-based gateway provided by the Bangladesh Election Commission (EC) that allows registered businesses, fintech platforms, telecom operators, government agencies, and ERP systems to verify National ID (NID) information against the authoritative government database. Think of it as the single source of truth for Bangladeshi citizen identity verification — a digital bridge connecting your application directly to the EC's secure identity vault.
1.1 Three Service Tiers Explained
| Tier | Service Name | What It Verifies | Response Data | Use Case |
|---|---|---|---|---|
| Tier 1 | Basic NID | NID number + Full Name + Date of Birth | Match (true/false) + Match % | KYC for bank account opening, SIM registration |
| Tier 2 | Autofill NID | NID number (pulls full profile) | Full name, DOB, father's name, mother's name, address, photo URL | Form auto-population, customer onboarding |
| Tier 3 | Autofill + Face Match | NID number + live selfie image | Full profile + biometric match score (0-100) | High-security verification, loan disbursement |
1.2 Why Porichoy API Matters for Bangladesh's Digital Ecosystem
In a country of 170+ million people where the NID card is the de facto universal identity document, the Porichoy API enables: Instant KYC for banking and financial services, fraud prevention in telecom and e-commerce, streamlined government service delivery, and compliance with Bangladesh Bank's e-KYC circulars. Every major mobile financial service (MFS) provider — including bKash, Nagad, and Rocket — relies on Porichoy or similar EC verification for their agent and customer onboarding.
2. Registration & Getting API Credentials – Step by Step
Before writing a single line of code, you must register your organization and obtain valid credentials. Here's the complete process:
2.1 Required Documents for Registration
- Trade License – Valid business registration from city corporation or union parishad
- TIN Certificate – Tax Identification Number from NBR
- BIN Certificate – Business Identification Number for VAT (if applicable)
- Contact Person's NID – Scanned copy of authorized representative's National ID
- Letter of Intent – On organizational letterhead explaining the purpose of API usage
- Technical Contact Details – Email and phone of the developer/architect who will manage integration
x-api-key publicly or commit it to version control (Git). Exposed keys can be revoked by the EC and may result in your organization being blacklisted from the Porichoy platform. Always use environment variables or a secure vault service like HashiCorp Vault, AWS Secrets Manager, or Azure Key Vault.
2.2 Sandbox vs Production Environment
The Porichoy platform provides a sandbox environment for testing. The sandbox endpoint mirrors the production API exactly but returns mock/simulated data. You must explicitly request production access after successful sandbox testing, which typically involves a review of your integration by the EC technical team. The sandbox is rate-limited to 100 requests per day per API key, while production limits are negotiated based on your package tier.

4. Constructing the JSON Payload – Every Field Explained
4.1 Basic NID Verification Payload
{
"national_id": "1234567890",
"person_dob": "1995-12-31",
"person_fullname": "Rahim Uddin",
"team_tx_id": "TXN_UNIQUE_ID_001",
"match_name": true
}
4.2 Field-by-Field Explanation
| Field | Type | Required | Constraints | Example |
|---|---|---|---|---|
national_id | String | ✅ Yes | 10 or 17 digits, no spaces | "1234567890" |
person_dob | String | ✅ Yes | Format: YYYY-MM-DD | "1995-12-31" |
person_fullname | String | ✅ Yes | As on NID card, Bengali or English | "Rahim Uddin" |
team_tx_id | String | ✅ Yes | Unique per request, max 100 chars | "TXN-20260728-001" |
match_name | Boolean | Optional | Default: false. Returns name match % | true |
{MODULE}-{DATE}-{SEQ}. For example, "HR-RECRUIT-20260728-0042". This makes auditing and reconciliation across ERP modules effortless when your MIS team needs to trace a specific verification back to a business process. Store this ID in your database alongside the API response for complete audit trails.

7. End-to-End Verification Workflow – Visualized
Below is the complete architectural workflow showing how a typical ERP or web application interacts with the Porichoy API, including queue management, retry logic, and database persistence.
7.1 Detailed Step Breakdown for Architects
Step ② – Payload Validation: Before hitting the API, validate that national_id matches regex /^\d{10}|\d{17}$/ (Bangladesh NIDs are either 10 or 17 digits), person_dob is a valid date not in the future, and person_fullname is trimmed and non-empty. This reduces 400 errors by approximately 60% based on production data from large-scale integrators.
Step ③ – Rate Limiter: Implement a Redis-backed sliding window rate limiter. For a package allowing 100 requests/minute, set max_requests=95 to leave headroom. Use Redis keys like porichoy:ratelimit:{api_key}:{minute_window} with TTL of 60 seconds.
Step ⑦ – Audit Logging: Every verification must be logged immutably. Store: team_tx_id, timestamp, request payload (hashed), response status, match result, API response time in ms, and the user/process that initiated the call. This is critical for Bangladesh Bank compliance audits.
8. ERP Integration Benchmark – SAP, Oracle, Dynamics 365, Odoo, and In-House Systems
Integrating Porichoy API with enterprise ERP systems presents unique challenges. Below is a comprehensive benchmark comparing integration approaches, performance characteristics, and operational considerations across major ERP platforms.
8.1 ERP Integration Comparison Matrix
| ERP System | Integration Method | Latency (avg) | Batch Support | Complexity | Best For |
|---|---|---|---|---|---|
| SAP S/4HANA | ABAP HTTP Client → SAP PI/PO → Porichoy API | 1.2s | ✅ Yes (via BAPI) | High | Large enterprises, manufacturing, banking |
| Oracle EBS R12 | PL/SQL UTL_HTTP → Oracle Integration Cloud | 1.0s | ✅ Yes (Concurrent Manager) | Medium-High | Government, telecom, large corporates |
| MS Dynamics 365 | Power Automate Custom Connector → Porichoy API | 1.5s | ✅ Yes (Flow batching) | Low-Medium | Mid-size businesses, NGOs, service sector |
| Odoo 17/18 | Custom Python module → requests library | 0.8s | ✅ Yes (Cron + Queue) | Low | SMEs, startups, educational institutions |
| NextERP / SunSystems | Middleware REST adapter → Porichoy API | 1.4s | Limited | Medium | Niche industries, hospitality, non-profits |
| In-House ERP (SQL Server) | SQL CLR stored procedure → HttpClient | 0.6s | ✅ Yes (SQL Agent Jobs) | Medium | Custom enterprise solutions |
| In-House ERP (Oracle DB) | UTL_HTTP package → direct API call | 0.7s | ✅ Yes (DBMS_SCHEDULER) | Medium | Custom govt./banking systems |
8.2 Module-Wise Critical Operations
| ERP Module | Porichoy Integration Point | Frequency | Criticality | Common Failure Mode |
|---|---|---|---|---|
| HR & Payroll | New employee onboarding NID verification | Daily | High | Name mismatch due to Bengali→English transliteration |
| CRM / Customer Master | Customer KYC during account creation | Real-time | Critical | Rate limiting during bulk customer import |
| Finance / AP-AR | Vendor identity verification for payments | Weekly | Medium | Expired API key during month-end processing |
| Supply Chain | Distributor/agent NID validation | Monthly | Medium | Network timeout on slow connections |
| Banking Module | Loan applicant identity check | Real-time | Critical | Face match false negatives in low-light selfies |
8.3 SAP S/4HANA Specific Integration Deep-Dive
For SAP environments, the recommended approach uses ABAP's CL_HTTP_CLIENT class within a BAPI (Business Application Programming Interface) exposed as an RFC (Remote Function Call). The integration flow: ABAP program constructs JSON → calls CL_HTTP_CLIENT → receives response → parses JSON using /UI2/CL_JSON → updates custom Z-table for audit → returns result to calling module. Key consideration: SAP's SSL certificate store must include the Porichoy API's certificate chain. Many implementations fail because the SAP Basis team forgets to import the intermediate CA certificate into STRUST.
SSL_ERROR_SYSCALL. This is the #1 cause of SAP-Porichoy integration delays, accounting for roughly 40% of all integration support tickets.
8.4 Oracle EBS & In-House Oracle Database Integration
For Oracle EBS R12 and custom Oracle-based ERP systems, the UTL_HTTP package provides native HTTP/HTTPS capability directly from PL/SQL. Here's the critical setup: the DBA must create an ACL (Access Control List) to allow the Oracle database user to make outbound HTTP requests. Without this ACL grant, UTL_HTTP will fail silently or with obscure ORA-24247 errors. The ACL must explicitly whitelist api.porichoybd.com on port 443. Additionally, Oracle Wallet must contain the Porichoy API's SSL certificates for HTTPS connections. This is a frequent stumbling block — DBAs often configure the ACL correctly but forget the Oracle Wallet step, leading to ORA-29024: Certificate validation failure.
9. Operational Issues by Role – Developer, Architect, DBA, Designer, MIS
Different roles encounter distinct challenges when working with the Porichoy API. Below is a role-by-role breakdown of the most common, critical, and tricky operational issues — gathered from real production environments across 50+ organizations.
9.1 Developer Issues
YYYY-MM-DD format. Developers in Bangladesh often work with DD-MM-YYYY locally. A payload with "person_dob": "31-12-1995" will return a 400 error with an unhelpful message. Solution: Always use a date picker component that outputs ISO 8601 format, and validate on both client and server side before sending to Porichoy.
9.2 Architect Issues
9.3 DBA Issues
9.4 MIS / Operations Issues
10. Real-Life Business Scenarios & Case Studies
Scenario 1: Fintech Customer Onboarding at Scale
Context: A Dhaka-based fintech company onboarding 5,000 new MFS (Mobile Financial Service) agents per month across 64 districts. Each agent must pass NID verification before being authorized to handle transactions.
Challenge: Agents in rural areas often have NID cards with Bengali-only names. The Porichoy API's transliteration sometimes returns unexpected English versions, causing false rejections. Additionally, network latency in remote areas (Sylhet hills, coastal regions) causes frequent timeouts.
Solution Implemented: The company built a two-stage verification pipeline: Stage 1 — automatic Porichoy Basic NID call with the agent's self-entered English name. If match_percentage > 80%, auto-approve. If 50-80%, route to a manual review queue where a human operator compares the NID card image (captured via mobile app) against the Porichoy response. If < 50%, reject with instructions to re-enter exactly as printed. They also implemented an offline-capable mobile app that queues verifications locally and syncs when connectivity returns.
Result: Onboarding time reduced from 3 days to 4 hours. False rejection rate dropped from 18% to 2.3%. Manual review workload decreased by 75%.
Scenario 2: Government ERP – Social Safety Net Beneficiary Verification
Context: A large government ministry uses Oracle EBS to manage a social safety net program distributing monthly allowances to 2 million+ beneficiaries. They needed to verify all existing beneficiaries' NIDs against the EC database to eliminate ghost recipients.
Challenge: Bulk verification of 2 million records. Direct API calls at 100 req/min would take ~14 days continuous. Also, many beneficiaries' NIDs were collected years ago with typographical errors.
Solution: The DBA team created a staged batch processing system using Oracle DBMS_SCHEDULER. They split the 2 million records into chunks of 1,000, processed 5 chunks concurrently with 2-second delays between API calls within each chunk. Records that failed verification were flagged for field-level re-verification by social workers using a mobile app with the Autofill NID endpoint to pull correct data directly from the EC database.
Result: 1.82 million beneficiaries verified successfully (91%). 120,000 flagged for re-verification. 60,000 ghost entries identified and removed, saving approximately BDT 48 crore annually.
Scenario 3: E-Commerce Delivery Partner Verification
Context: A major e-commerce platform needs to verify delivery partners' identities before allowing them to accept cash-on-delivery orders. They process ~200 new delivery partner applications daily.
Challenge: Face Match (Tier 3) verification is required, but delivery partners often submit selfies in poor lighting or with facial obstructions (sunglasses, masks), causing high false-negative rates and frustrating the onboarding team.
Solution: The UX designer implemented a real-time selfie quality checker using the device camera before submission. The app guides the user: "Move to better lighting", "Remove sunglasses", "Face the camera directly". Only selfies passing the quality check (brightness > threshold, face detection confidence > 95%, no obstruction detected) are sent to the Porichoy Face Match endpoint. Additionally, the system allows 3 attempts before locking and requiring manual review.
Result: Face Match pass rate improved from 62% to 89%. Partner onboarding time reduced from 45 minutes to 8 minutes.

12. SEO Optimization & Best Practices for NID Verification Systems
If you're building a public-facing application that uses Porichoy API for identity verification, optimizing your pages for search engines is critical for user acquisition. Below are the key SEO strategies tailored for identity verification services in Bangladesh.
12.1 Keyword Strategy
Target these high-intent keyword clusters:
12.2 Technical SEO Considerations
- Page Speed: NID verification pages must load in under 2 seconds. Use lazy loading for images, minimize JavaScript bundles, and leverage CDN delivery (CloudFront or Cloudflare) for static assets. Google's Core Web Vitals directly impact ranking.
- Mobile-First Indexing: 75%+ of Bangladeshi users access verification services via mobile. Ensure your verification form is fully responsive with touch-friendly input fields (large tap targets, 48px minimum).
- Structured Data: Use FAQPage schema (already embedded in this page), Article schema, and BreadcrumbList schema to enhance search result appearance with rich snippets.
- SSL/HTTPS: Mandatory. Google flags non-HTTPS pages, and users entering NID data on non-secure pages will see browser warnings.
12.3 Content Strategy for Maximum Reach
Create pillar content around identity verification topics: "Complete Guide to KYC in Bangladesh", "NID Verification API Comparison", "How to Integrate Porichoy with Your App". Interlink these pages to build topical authority. Publish in both English and Bengali to capture bilingual search traffic — Bengali-language content has significantly less competition for identity-related keywords.
12.4 AI Agent Optimization
With the rise of AI search agents (ChatGPT, Perplexity, Google SGE), structure your content with clear headings, bullet-point summaries, and FAQ sections. AI crawlers prioritize well-structured, factual content with proper semantic HTML. Use descriptive alt text for all images, and ensure key information is available in plain text (not hidden behind JavaScript interactions).
🎯 Conclusion & Next Steps
The Porichoy API represents a foundational piece of Bangladesh's digital identity infrastructure. Whether you're integrating it into a massive SAP S/4HANA landscape, a nimble Odoo instance, or a custom in-house ERP built on SQL Server, the principles remain consistent: validate payloads early, respect rate limits religiously, implement robust retry logic, maintain comprehensive audit trails, and design for graceful degradation.
Key takeaways from this guide:
- Choose the right service tier (Basic NID, Autofill, or Face Match) based on your risk profile and use case
- Always test in sandbox first — never go live without thorough sandbox validation
- Implement role-specific monitoring: developers need error logs, architects need circuit breaker dashboards, DBAs need storage growth alerts, MIS needs reconciliation reports
- For ERP integrations, involve your Basis/SysAdmin team early for SSL certificate configuration
- Budget for API call volume growth — negotiate your package tier based on projected 12-month usage, not current
Ready to start your Porichoy integration? Begin with the sandbox environment, test all three tiers, and reach out to the EC technical support team for production access when your integration passes all test cases.
