The Tallyfy REST API lets developers build custom connections to our core platform features through code-based integrations and smart automation.
Tallyfy’s “API-first” approach means our public API gives you the same functionality that powers our web app - so you get thoroughly tested, reliable access to everything. This foundation guarantees stable APIs for your mission-critical integrations.
Why is the Tallyfy API valuable for custom integrations?
The Tallyfy API becomes essential when you need custom workflow solutions that go beyond our standard interface.
API integration lets you embed Tallyfy functionality right into your existing business apps, automate complex workflows across multiple systems, and create completely customized user experiences. Instead of forcing people to switch between different systems, the API brings Tallyfy’s capabilities into the tools your team already uses every day.
This smart integration approach seriously improves user adoption, boosts productivity, and keeps your data consistent across all your systems.
What capabilities does the Tallyfy API provide?
The API lets you build custom connections, automate complex workflows between Tallyfy and external systems, and extend Tallyfy way beyond what our standard platform offers.
Tallyfy provides three secure authentication methods for programmatic API access:
User Token Authentication: Get a token for specific Tallyfy users (from their profile or through our API). Your app works with that user’s exact permissions and access.
Application Token Authentication (Enterprise Plans): Get app-level credentials (client ID & secret) so your application can act on behalf of multiple users. Perfect for server-to-server connections or multi-user apps.
OAuth Authentication Flow (Enterprise Plans): The industry-standard secure way that lets users give your app access to their Tallyfy data without sharing passwords. We recommend this for third-party apps. Learn more.
What headers are required for Tallyfy API requests?
Every API request must include these mandatory headers:
Authorization: Bearer {your_access_token} // Your user or app token
Content-Type: application/json // Tells Tallyfy you're sending JSON data
X-Tallyfy-Client: APIClient // **Required** - Identifies the request source
What functionality can I access through the Tallyfy API?
The API provides comprehensive access to core Tallyfy features, including:
The Tallyfy REST API enables workflow integration through user-based or application-based authentication methods while supporting multi-organization contexts and providing webhooks for event-driven functionality.
The Tallyfy REST API documentation provides code samples across multiple programming languages for integrating with the platform using proper authentication headers and base URL endpoints.
A detailed walkthrough for integrating third-party applications with Tallyfy API using client credentials to make API requests and manage users through secure token-based authentication and authorization flows.
The Tallyfy API requires proper authentication through personal access tokens or OAuth flow along with specific headers to enable secure platform access and custom integrations.
