Frequently asked questions

We answer your technical questions

Answers to the most common questions about the API and integrations with FacturaDirecta.

The API uses OAuth2 for authentication, the industry standard for REST APIs. Each application receives unique credentials (Client ID and Client Secret) to authenticate securely. Access tokens have a limited validity and can be renewed using refresh tokens.

The complete API documentation is available at www.facturadirecta.com/api. It includes reference for all endpoints, code examples in different languages, authentication guides, and common use cases.

Sandbox environments have no request limits so you can develop and test freely. In production, we apply reasonable rate limiting to ensure service stability, but they are high enough for most use cases. Contact us if you need custom limits.

Yes, you can create multiple sandbox environments. Each sandbox is completely independent with its own API keys, users, and data. This allows you to have separate environments for development, testing, staging, or different projects.

You can integrate FacturaDirecta in two ways: through our REST API for custom integrations, or using Zapier to connect with over 5,000 applications without coding. Zapier allows you to automate workflows between FacturaDirecta and your favorite tools like CRM, spreadsheets, email, and more.

We are currently working on official SDKs for the most popular languages (Python, PHP, Node.js, Ruby). In the meantime, you can use any standard HTTP client in your favorite language to consume our REST API. Check the documentation for code examples.

We offer specialized technical support for developers. You can contact our technical team to resolve questions about the API, integration, or best practices. Partners have access to priority support with faster response times.
