API Authentication

Learn how to authenticate your API requests to Resync.

API Keys​

All API requests require authentication using an API key. API keys are unique to your account and should be kept secure.

Get Your API Key​

  1. Log in to Resync Dashboard
  2. Navigate to Settings → API Keys
  3. Click Create API Key or copy an existing one
  4. Store it securely (it won't be shown again!)

Authentication Methods​

SDK Authentication​

For client-side SDKs (JavaScript, React Native):

import Resync from 'resync-javascript';

await Resync.init({
  key: 'your-api-key',
  appId: 7,
  storage: localStorage,
  environment: 'production',
});

REST API Authentication​

For server-side REST API requests:

curl -H "Authorization: Bearer your-api-key" \
     https://api.getresync.com/v1/campaigns

Troubleshooting​

"Invalid API key" Error​

  • Check that you're using the correct key
  • Ensure the key hasn't been deleted
  • Verify there are no extra spaces or characters

"Unauthorized" Error​

  • Confirm the API key is active
  • Check that you have the necessary permissions
  • Ensure you're using the Bearer token format for REST APIs

Rate Limit Exceeded​

  • Implement exponential backoff
  • Cache responses when possible
  • Consider upgrading your plan
