Changefly API

Are you a developer? Stop using email and phone numbers to authenticate users (here's why). Changefly ID is next-generation protection for logins, payments, identification, user paywalls, bot paywalls, loyalty programs, comments, surveys, forms, and more. Follow these 3 easy steps to protect the privacy and security of your users and content:

Step 1 — Generate your Changefly Private Key

Changefly required – go here to get the free Changefly app

cURL example:

curl -X POST https://services.changeflyapi.com/v1/api/generate-private-key \
  -H "Content-Type: application/json" \
  -d '{
    "admin_changefly_id": "YOUR CHANGEFLY ID",
    "admin_changefly_pin": "YOUR CHANGEFLY PIN"
  }'

JSON reponse:

{
    "status": "OK",
    "response": {
        "success": 1,
        "api_private_key": "YOUR API PRIVATE KEY"
    }
}

Step 2 — Generate your Changefly Connection Key

cURL example:

curl -X POST https://services.changeflyapi.com/v1/api/generate-connection-key \
  -H "Content-Type: application/json" \
  -d '{
    "admin_changefly_id": "YOUR CHANGEFLY ID",
    "admin_changefly_pin": "YOUR CHANGEFLY PIN"
  }'

JSON reponse:

{
    "status": "OK",
    "response": {
        "success": 1,
        "api_connection_key": "YOUR API CONNECTION KEY"
    }
}

Step 3 — Start authenticating Changefly ID’s

cURL example:

curl -X POST https://services.changeflyapi.com/v1/api/authenticate \
  -H "Content-Type: application/json" \
  -d '{
    "api_private_key": "YOUR API PRIVATE KEY",
    "api_connection_key": "YOUR API CONNECTION KEY",
    "ip_address": "USER IP ADDRESS",
    "changefly_id": "USER CHANGEFLY ID"
  }'

For security reasons, a Changefly PIN may also be required if something suspicious is detected (like an IP address mismatch):

curl -X POST https://services.changeflyapi.com/v1/api/authenticate \
  -H "Content-Type: application/json" \
  -d '{
    "api_private_key":"YOUR API PRIVATE KEY",
    "api_connection_key":"YOUR API CONNECTION KEY",
    "ip_address":"USER IP ADDRESS",
    "changefly_id":"USER CHANGEFLY ID",
    "changefly_pin":"USER CHANGEFLY PIN"
  }'

JSON reponse:

{
    "status": "OK",
    "response": {
        "success": 1,
        "changefly_connection_id": "UNIQUE ID ASSIGNED TO USER"
    }
}

IMPORTANT

Changefly ID is free for personal projects. You are responsible for backing up your Changefly API keys.
