Developer Docs

Build on the ArelHub platform with reliable, customer-safe API guidance.

Start with the public contract, secure your integrations, and use the approved messaging and webhook flows for production delivery.

Get started API Reference
Overview

Everything you need to integrate with confidence

ArelHub exposes a curated public API for customer-facing authentication, account setup, messaging orchestration, status checks, and inbound webhook handling. Staff, admin, and internal tooling remain out of scope for the external docs surface.

  • Public-facing auth and account bootstrap routes
  • Customer messaging and status APIs
  • Webhook contracts for inbound delivery events
  • Production-safe limits, retries, and support guidance
Getting started

Start with the essentials

Create an account, configure your organization, verify your sending profile, and use the public auth flow to mint a user token or API key.

  • Account creation and onboarding checklist
  • Authentication flows for user and API-key access
  • Message send, status, and cost understanding
  • Delivery and safety controls before go-live
Authentication

Use the correct scheme for each workflow

Customer integrations should follow the documented public auth flow and use JWT or API-key access only where approved for that route.

  • Account bootstrap and user authentication
  • Email OTP verification flows
  • External OAuth, provider linking, and callback handling
  • Signed requests and safe token handling
Messaging

Send, track, and manage messages

Use the public platform API for message submission, delivery monitoring, status retrieval, and quota-aware operations.

  • Message submission and queueing
  • Cost and segment-aware pricing previews
  • Delivery status and retry handling
  • Operational guardrails and throttling guidance
Webhooks

Keep event-driven integrations reliable

Public webhook receivers are designed for provider callbacks and customer state changes. Validate signatures, handle retries safely, and prefer idempotent handlers for message and carrier events.

  • Inbound webhook receiver contracts
  • Delivery event handling and retry semantics
  • Out-of-band status and billing updates
  • Operational support and incident response
