STACKSYNC WORKFLOW AUTOMATION

Everything serious workflow automation needs.

Human approvals, governance, secrets, and a connector kit for anything you can't find off the shelf — the controls that make automation safe to run in production.

HUMAN IN THE LOOP

Pause for a human
exactly when it matters.

Insert approval steps anywhere in a workflow. The run pauses with the full payload, waits for a decision — approve, reject, or edit — then continues. No lost state, no timeouts, no shadow spreadsheets.

See approvals in action
  1. 01 Drop approval gates into any workflow without writing glue code
  2. 02 Runs pause safely with full context and wait for a human decision
  3. 03 Every approval is logged, attributable, and replayable end to end

Runs pause safely with full context until a human decides — no timeouts.

SECURITY & GOVERNANCE

Feature controls, audit logs,
and governance built in.

Role-based access controls decide who can build, run, and deploy. Every deploy, run, secret access, and approval is captured in an immutable audit log your compliance team can actually sign off on.

Explore governance
  1. 01 Granular RBAC across workflows, runs, secrets, and approvals
  2. 02 Immutable, attributable audit log of every action and deploy
  3. 03 SOC 2 Type II, ISO 27001, HIPAA — governance you can prove

VARIABLES & SECRETS

Secrets and variables,
managed the right way.

Store API keys, tokens, and environment variables in an encrypted vault and reference them anywhere with a single expression. Values are injected at runtime, scoped per environment, and never hard-coded or written to a log.

Manage secrets
  1. 01 AES-256 encrypted at rest, injected only at runtime
  2. 02 Scope values per environment — prod, staging, and dev stay separate
  3. 03 Reference any secret with {{ secrets.NAME }} — never paste a key again
Secrets Variables
AES-256 · encrypted at rest
STRIPE_API_KEY •••••••••••• prod
NETSUITE_TOKEN •••••••••••• prod
WEBHOOK_SIGNING_SECRET •••••••••••• staging
OPENAI_API_KEY •••••••••••• prod
BASE_URL https://api.acme.com var
Referenced in workflow injected at runtime
headers.Authorization = "Bearer " + {{ secrets.STRIPE_API_KEY }}

Injected at runtime — never hard-coded, never written to a log.

CONNECTOR DEVELOPMENT KIT

Describe the API.
AI builds the connector.

Don't have a connector? Describe the API in plain English and the Connector Development Kit scaffolds it for you — auth, endpoints, schema, and tests — so you can sync any system on your stack in minutes, not weeks.

Build a connector
  1. 01 AI generates auth, endpoints, and schemas from a plain-English brief
  2. 02 Full code access — extend, version, and test like any other connector
  3. 03 Ship a private connector for any internal or long-tail API
Build a connector for the Acme Billing REST API

Generated 4 endpoints · auth configured · 6/6 tests passing

Describe any API in plain English — the CDK writes, tests, and versions the connector.

CONNECTORS

1,000+ connectors.
And AI builds for the rest.

We support every major SaaS and database out of the box. If yours isn't listed, paste an API URL and our agent will spec, build and ship a connector, typically in under a minute.
