1 Best APIs for Audit Log in Nigeria

Warrant is an authorization-as-a-service platform that provides APIs for implementing fine-grained, scalable access control in applications — replacing the complex custom permissions systems that most engineering teams build from scratch. Authorization — determining whether a specific user is allowed to perform a specific action on a specific resource — is a fundamental requirement of virtually every application, but implementing it correctly is notoriously difficult. Warrant externalizes this complexity into a dedicated service, providing simple APIs for defining roles, permissions, and object-level access rules, and a fast check API for enforcing those rules at request time. Nigerian B2B SaaS companies and enterprise software teams face authorization complexity as a daily challenge. A Nigerian project management platform needs to ensure that Company A users never see Company B projects, that project managers can assign tasks but viewers cannot, and that document owners can share access with specific individuals. Implementing this with custom database queries and application logic is error-prone, hard to audit, and increasingly complex as the permission model grows. Warrant solves this with a model-driven approach: define the access structure once, and the check API handles enforcement. Warrant supports two complementary access control models. Role-Based Access Control (RBAC) assigns users to roles (admin, editor, viewer) and permissions to roles — a user gets all permissions of their assigned roles. This model works well for simple, hierarchical permission structures. Relationship-Based Access Control (ReBAC), inspired by Google Zanzibar, defines access based on direct relationships between users and objects — "User X is the owner of Document Y," "Group G has edit access to Project P," "User X is a member of Group G." ReBAC enables the rich, object-level sharing models used by Google Docs, Dropbox, and modern collaboration tools. The core Warrant Check API (/v2/check) accepts a subject (who), relation (what action), and object (what resource) and returns an allow or deny decision in milliseconds. Nigerian applications call this API at every access-sensitive operation — before rendering a page, before executing a database query, before returning API data. The check API handles all the relationship traversal and permission inheritance logic, returning a simple boolean decision. The Warrant Warrant Query Language (WQL) enables complex authorization queries: "What objects does User X have edit access to?" or "Who has access to this document?" These queries power features like permission-filtered list views where users only see resources they are authorized to access — a common requirement in Nigerian multi-tenant SaaS applications. Warrant is self-hostable via Docker for Nigerian teams that need data residency control or want to avoid third-party dependencies for their authorization system. The hosted service provides 1 million authorization checks per month on the free tier — sufficient for many Nigerian applications in early stages. SDKs are available for Node.js, Python, Go, Ruby, and Java.
