Why Developers Choose Our REST API
Lightweight & Efficient
REST APIs use JSON/XML which requires less bandwidth and processing power than a SOAP-Based API XML structure.
Simple Implementation
The REST-API follows standard HTTP methods (GET, POST, PUT, DELETE) that developers are already familiar with, making integrations easy and straightforward.
Flexibility in Data Formats
The REST-API supports multiple data formats including JSON, XML, HTML, and plain text.
TINCheck offers a SOAP-based API upon request.
The TINCheck API was built with developers in mind. Our secure REST-based API ensures your sensitive customer and vendor data remains protected throughout the verification process, with enterprise-grade encryption and dedicated API keys that never expose your platform credentials.
How TINCheck API Works:
Automated TIN Validations that Work with Your Existing Platforms
