Solution & integration design
Muqawil Platform — Release 4
1. Solution overview
The platform is the unified Muqawil portal, a membership-request workflow and forms engine, a central integration layer and a contractor, member and request data store, hosted on a licensed cloud inside the Kingdom with a 99.9% availability target.
2. Integration map
| Platform | Purpose | Pattern | Status |
|---|---|---|---|
| Nafath | Single sign-on | Synchronous — OIDC | In testing |
| Absher | Verifying the firm’s authorised person | Synchronous — REST | Done |
| Government Service Bus | Commercial register, Balady and Etimad data | Asynchronous — messaging | In build |
| SADAD | Membership and certificate fee payment | Nightly batch | Planned |
Every interface goes through the central API gateway; the Government Service Bus uses asynchronous messaging so a slow agency never blocks a membership request, with automatic retries and an audit trail for every message.
3. Simulator & fallback
A local simulator of the Nafath, Government Service Bus and Absher interfaces is built in the first integration sprint, so the team keeps working when the national test environments go down — as they did for nine days in September.
4. Data model
- Contractor: commercial registration, authorised person, membership class, contacts, consents
- Request: type (membership, renewal, certificate, project registration), stage, attachments, time limit
- Check: Service Bus message number, issuing agency, status, reply date
- Log: every change with who, when and through which channel
5. Cybersecurity & data protection
- Compliance with the ECC-2:2024 and the cloud cybersecurity controls
- Personal data encrypted at rest and in transit under the PDPL
- An independent penetration test before launch with no critical or high findings
- Round-the-clock monitoring from the security operations centre
