The Klara API is a RESTful API that allows partners to programmatically create RFI requests and applications.

​
Environments

Klara provides two environments for API access:
EnvironmentBase URLPurpose
Sandboxhttps://sandbox.klara-ai.com/api/externalTesting and development
Productionhttps://app.klara-ai.com/api/externalLive integrations
Use the sandbox environment to test your integration before going live. Sandbox and production use separate API keys—generate sandbox keys from the sandbox dashboard.
Sandbox data may be periodically reset. Do not use sandbox for production workloads.

​
Authentication

Include your API key in the Authorization header: 
Authorization: Bearer klara_{client_id}.{secret}
See Authentication for details on obtaining and managing API keys.

​
Request format

  • All request bodies must be JSON
  • Set the Content-Type: application/json header

​

Successful responses return JSON with the requested data. Error responses include an error field with details: 
{
  "error": "Missing required fields",
  "required": ["company_name", "country", "primary_contact.name", "primary_contact.email"]
}
