Zapier SDK Lets Builders Replace Multi-Step Sub-Zaps With Code.

Zapier’s new SDK is being used by automation builders to consolidate complex Sub-Zaps into a single JavaScript code step. In the example shared on LinkedIn, a 24-step Zapier workflow for matching email and meeting participants to Notion CRM contact records was refactored into one code step while preserving the same logic and outputs.

Key details from the post:

• The original Sub-Zap handled contact matching for a Notion CRM workflow.
• It used multiple components, including paths, filters, looping, AI-based classification, Zapier Tables lookups, Notion record creation, and return values to a parent Zap.
• The refactored version reduced that internal logic to one JavaScript code step, plus the Sub-Zap start and return steps.
• The reported benefit was not simpler-looking workflows, but faster iteration.
• The post argues that coding agents such as Claude Code can make updates easier by editing the workflow logic directly in code and reducing the need to manually reconfigure many visual steps.

For small business owners and builders, this suggests a shift in how Zapier automations may be maintained: fewer visual blocks for complex logic, with more work moving into code-assisted development. That could make advanced automations faster to update for teams comfortable using AI coding tools, while also raising the skill threshold for users who prefer no-code interfaces.
