​
API Key Authentication

All Tellscope API requests are authenticated using an API key. Unlike traditional REST APIs that use headers, the Tellscope GraphQL API accepts the API key as a parameter in each query or mutation.

​
API Key Format

Your API key follows this format: 
tellscp_sk_XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
  • Prefix: tellscp_sk_ (identifies it as a Tellscope secret key)
  • Suffix: Unique alphanumeric identifier

​
Using Your API Key

Pass the apiKey parameter in every query or mutation: 
query {
  feedbackItems(apiKey: "tellscp_sk_YOUR_API_KEY", take: 10) {
    items {
      id
      title
    }
    total
  }
}

mutation {
  addFeedbackItem(
    apiKey: "tellscp_sk_YOUR_API_KEY"
    input: {
      source: "api"
      title: "Customer feedback"
      content: "Great product!"
    }
  ) {
    id
  }
}

​
Managing Your API Key

​
Generate a New Key

  1. Log in to Tellscope Dashboard
  2. Go to Settings → API
  3. Click Generate API Key
  4. Copy and store the key securely

​
Regenerate Key

If your API key is compromised:
  1. Go to Settings → API
  2. Click Revoke & Regenerate
  3. Confirm the action
  4. Update your applications with the new key
Regenerating your API key immediately invalidates the old key. All applications using the old key will stop working.

​
Security Best Practices

Server-side only

Never expose your API key in client-side code, mobile apps, or public repositories.

Environment variables

Store your API key in environment variables, not in source code.

Rotate regularly

Regenerate your API key periodically as a security measure.

Monitor usage

Check the dashboard for unusual API activity.

​
Example: Secure Usage

// ✅ Good: API key from environment variable
const apiKey = process.env.TELLSCOPE_API_KEY;

const response = await fetch('https://api.tellscope.io/graphql', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    query: `query { feedbackItems(apiKey: "${apiKey}") { items { id } } }`
  })
});

// ❌ Bad: Hardcoded API key
const response = await fetch('https://api.tellscope.io/graphql', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    query: `query { feedbackItems(apiKey: "tellscp_sk_abc123...") { items { id } } }`
  })
});
