Authentication

Every Publer API request must include a valid API key. This guide shows you how to obtain, use, and manage your keys securely.

Obtaining an API Key

1. Sign in to your Publer account (Business plan).

2. Navigate to Settings → Access & Login → API Keys.

3. Click Create API Key.

4. Enter a descriptive name for your key.

5. Select only the scopes your integration needs (e.g., posts, media, accounts).

6. Click Create.

7. Copy and securely store the key — you won’t see it again.

Using Your API Key

Include your key in the Authorization header for every request. Also provide your workspace ID:

Authorization: Bearer-API YOUR_API_KEY  
Publer-Workspace-Id: YOUR_WORKSPACE_ID  
Content-Type: application/json

Example (list posts):

curl -X GET https://app.publer.com/api/v1/posts \
  -H "Authorization: Bearer-API YOUR_API_KEY" \
  -H "Publer-Workspace-Id: 5f8d7a62c9e77e001f36e3a1"

API Key Scopes

When creating an API key, you must select specific permission scopes based on your integration needs:

Scope	Description	Example Endpoints
workspaces	Retrieve user's workspaces	/workspaces
accounts	Retrieve user's accounts of selected workspace	/accounts
posts	Manage user's posts	/posts
media	Upload and list media assets	/media

Common Authentication Errors

• 401 Unauthorized • Missing or invalid Authorization header • Key revoked or expired

• 403 Forbidden • Insufficient scopes for the endpoint • Missing Publer-Workspace-Id header

Always inspect the JSON error response for message and code.

Security Best Practices

• Environment Variables Store your key outside code—e.g., in a .env file:

  PUBLER_API_KEY=your_api_key_here

• Secrets Management Use a vault (AWS Secrets Manager, Azure Key Vault, HashiCorp Vault).

• Key Rotation Rotate keys every 90–180 days, or after team changes/incidents.

• Least Privilege Create separate keys for different use cases.

• Safe Logging Never log full keys; mask all but the last 4 characters:

  console.log(`Using key ***${apiKey.slice(-4)}`);

• Always HTTPS Never send keys over plain HTTP.

Troubleshooting

If you continue to see authentication errors:

1. Confirm your key is active and not expired.

2. Verify you have the correct header names and values.

3. Double-check that your key has the required scopes.

4. Contact [email protected] for assistance.
