API & Integrations

Build on Flowstack

Programmatic access to contacts, companies, pipeline, forms, submissions, and AI scoring. Push data in, pull intelligence out.

Request API access →info@6away.ai
RESTful JSON API
Standard REST endpoints with JSON request/response bodies. Predictable URLs, HTTP verbs, and status codes.
Bearer token auth
API keys with workspace-level scoping. Keys are hashed at rest — never stored in plaintext.
Webhook delivery
Real-time event notifications with HMAC-SHA256 signatures for payload verification.
Rate limiting
1,000 requests/min on Pro, 5,000/min on Business. Headers indicate remaining quota.
Pagination
Cursor-based pagination on all list endpoints. Consistent meta object with total count.
Idempotency keys
Pass an Idempotency-Key header on POST requests to safely retry without duplicates.
