Blocks

Blocks are the smallest reusable units in Orvanta workflows.

A block usually wraps one responsibility: an API call, validation step, transform, or side effect.

Example block types

• Stripe payments
• Slack notifications
• AWS S3 operations
• HTTP webhooks
• Data transformation and mapping

Good block design

• Single responsibility
• Explicit input/output contract
• Idempotent behaviour where possible
• Clear error semantics (retryable vs terminal)

Composition pattern

Build workflows by combining blocks into deterministic execution graphs, then version the resulting artifact.
