Authentication

This API supports two authentication methods:

Recommended

API Key

Add your API key as a request header:

X-Api-Key: YOUR_API_KEY

Bearer Token (JWT)

If you have a token, send it using:

Authorization: Bearer YOUR_JWT
Keep keys private

Never expose API keys or bearer tokens in frontend code. Use them from server-side code only.

Obtaining a Bearer Token

If you prefer to authenticate using a Bearer token (JWT), you can obtain one by calling the login API with your ExportJson account credentials.

POST /api/login

Send your credentials as a JSON body. On success, the API returns a JWT token which can be used in subsequent requests.

Request

{
  "username": "user@example.com",
  "password": "your-password"
}

Response

{
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
}

Using the token

Include the token in the Authorization header for API requests:

Authorization: Bearer YOUR_JWT_TOKEN
Important notes
  • Bearer tokens expire ervy 10 minutes automatically.
  • Tokens grant full access to your account and credits.
  • Do not expose tokens in frontend code or public repositories.
  • For long-running integrations, API keys are recommended instead.
