TL;DR:
- A REST API and webhooks included on every paid plan
- A public integration guide covering authentication, rate limits, and error codes; the endpoint reference is available to signed-in tenants
- JWT authentication with rate limiting
- Webhook integrations for real-time event processing
Why an API Matters for Contractors
Field service businesses don't operate in isolation. Your scheduling software needs to talk to your accounting system. Your dispatch needs GPS data. Your invoicing needs payment processing. Your phone system needs customer records.
A documented, tenant-scoped API is the difference between a platform that integrates with your workflow and one that becomes a data silo.
What the Exoserva API Covers
The API covers the areas contractors integrate most often:
- Core operations: customers, jobs, dispatch, scheduling, properties, assets, technicians, and inventory
- Financial and billing: invoices, estimates, payments, and the price book
- Team and access: users, roles, API keys, time tracking, and settings
- Communications and voice: voice AI, conversations, SMS and email, and notifications
- AI and automation: AI agents, analysis, and workflows
- Integrations and data: payment and phone webhooks, lead sources, and documents
Authentication
Every API request requires a JWT Bearer token obtained from the login endpoint:
Authorization: Bearer <access_token>
Access tokens expire in 1 hour. Refresh tokens (7-day TTL) enable seamless rotation without user interruption.
Rate Limiting
| Endpoint Type | Limit |
|---|---|
| Standard API | 500 requests/minute |
| Auth endpoints | 30 requests / 15 minutes |
| Stripe webhooks | 1,000 requests/minute |
| Other webhooks | 100 requests/minute |
Multi-Tenant by Design
Every API request is scoped to a tenant. The JWT token contains the tenant ID, and every database query filters by it. There is no way to accidentally access another tenant's data through the API.

FAQ
How do I get API access?
API access is included with every paid Exoserva plan. Generate your API key from Settings → API Keys in the dashboard; the endpoint reference for your plan is in your account under Developers once you sign in.
Is there a sandbox environment?
Yes. Development API keys point to a sandbox environment where you can test without affecting production data.
What format does the API use?
JSON exclusively. All requests and responses use Content-Type: application/json.
