API Keys
Create and manage API keys to authenticate requests to the PDFSimple API. Learn best practices for keeping keys secure.
The PDFSimple API lets you integrate PDF processing into your own applications. Every API request must be authenticated with an API key that you generate in your dashboard.
Creating an API key
- Log in to your PDFSimple account.
- Navigate to Dashboard → API Keys.
- Click Create new key and give it a descriptive name.
- Copy the key immediately — it is shown only once.
Your API key is a secret credential. Never commit it to source control, expose it in client-side code, or share it publicly. Treat it like a password.
Using the API key
Send the API key in the Authorization header of every request:
Authorization: Bearer YOUR_API_KEYRotating and revoking keys
You can create multiple API keys (e.g., one per environment) and revoke any key at any time from Dashboard → API Keys. Revoking a key immediately invalidates all requests using that key.
API access uses a credit-based billing model separate from web plan tasks. See the Credits & Rate Limits article for details.
