# Think AI Developer Ecosystem Guide

Think AI supports a complete developer ecosystem: SDKs, connectors, plugins, extensions, low-code components, enterprise integrations, and native Think AI tooling.

## Core Integration Rule

Human login may use OTP. System-to-system API integrations must not use OTP.

Use one of these authentication methods for integrations:

- API key
- Service account
- OAuth2 client credentials
- OpenID Connect
- SAML-backed enterprise SSO
- Signed JWT
- mTLS for regulated enterprise environments

Recommended headers:

```http
Authorization: Bearer <access_token>
X-API-Key: <scoped_api_key>
X-Tenant-ID: <tenant_id>
X-Request-ID: <request_id>
X-Correlation-ID: <correlation_id>
```

## How To Handle Customer Integrations

1. Create the tenant and service account.
2. Generate scoped API credentials.
3. Route every request through the Think AI API Gateway.
4. Send tenant ID, request ID, and correlation ID.
5. Process data transiently by default.
6. Store only metadata, metrics, audit events, and approved derived outputs.
7. Validate response contracts in the customer system.

## Payment Boundary

Payment providers are central-only. Customer deployments must not receive Think AI payment gateway credentials, merchant keys, subscription billing code, or internal pricing logic.

Payment flow:

Customer agreement/payment -> Think AI central billing -> signed license -> customer deployment -> local license validation.
