Authentication

All Twenty2 API requests must include a valid API key in the request header. API keys are scoped per workspace — a key from one workspace cannot access resources in another.

How to Get Your API Key

1. Log in to your Twenty2 workspace

2. Go to Profile → Integrations → Build with Twenty2 API

3. Click API Keys → Create New

4. Copy the generated key and store it securely

Using Your API Key

Pass your API key as a Bearer token in the Authorization header on every request.

curl -X POST https://api.twentytwo.in/api/calls \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json"

headers = {
  "Authorization": "Bearer YOUR_API_KEY",
  "Content-Type": "application/json"
}

const headers = {
  "Authorization": "Bearer YOUR_API_KEY",
  "Content-Type": "application/json"
};

req.Header.Set("Authorization", "Bearer YOUR_API_KEY")
req.Header.Set("Content-Type", "application/json")

request['Authorization'] = 'Bearer YOUR_API_KEY'
request['Content-Type'] = 'application/json'

Managing API Keys

You can create, view, and revoke API keys anytime from Profile → Integrations → Build with Twenty2 API → API Keys. If a key is compromised, revoke it immediately and generate a new one.
