Captur SDK Gen3

Purpose​

Captur SDK Gen3 is intended to simplify how customers integrate and evolve real-time validation workflows within their mobile applications.

It builds on the existing capabilities of the current SDK with the following primary goals:

  • Session based configuration and workflow management
  • Multi-model and multi-policy workflows
  • Temporary offline support in a single workflow
  • Fine-tuned policy management in supported locations

This is an evolution of the current SDK designed to build and improve upon existing functionality.

Core Concepts

Session-Based Workflow Model​

Captur SDK Gen3 introduces a clearer session lifecycle model.

A session represents:

  • configuration resolution
  • model preparation
  • camera interaction
  • inference
  • result generation

Multiple sessions may exist within a single customer workflow.

Multi-Model and Policy Support​

Captur SDK Gen3 is designed around the assumption that customers may require:

  • multiple policies for the same validation domain
  • multiple models within a single workflow
  • deployment-specific behavior by customer or location

The SDK surface is intentionally designed to support these scenarios without multiplying API keys or SDK integrations.

Low Connectivity Modes​

Partial offline functionality will be supported in the new SDK but will not be available at launch while we collect data and improve performance.

Flexible Policy Evolution​

Policies are expected to evolve over time as models improve and operational requirements change.

Captur SDK Gen3 is designed so that:

  • Validation configuration can evolve independently of SDK releases
  • Captur manages a more fine-tuned policy structure server-side
  • customers maintain a stable integration surface

Improved Observability​

Captur SDK Gen3 introduces clearer lifecycle and telemetry events around:

  • session creation
  • configuration resolution
  • model download
  • inference lifecycle
  • upload behavior
  • error states

The intention is to improve both customer integration debugging and internal operational visibility.

Cross-Platform Support

Captur SDK Gen3 is planned for:

  • iOS (Swift)
  • Android (Kotlin)
  • React Native

with aligned architectural concepts and configuration behavior across platforms.
