GraphQL has revolutionized the way developers interact with APIs, and TNID's GraphQL implementation offers powerful capabilities for digital identity and authentication. In this blog post, we'll explore how to effectively use TNID's GraphQL APIs with Python.
<br>
<br><h2 class="mt-5 mb-3"> Getting Started with TNID GraphQL
<br>
<br><h2 class="mt-5 mb-3"># Prerequisites
<br><li>Python 3.7+
<br><li>`requests` library
<br><li>TNID API credentials
<br>
<br><h2 class="mt-5 mb-3"># Installation
<br>```python
<br>pip install requests
<br>```
<br>
<br><h2 class="mt-5 mb-3"> Authenticating GraphQL Requests
<br>
<br>```python
<br>import requests
<br>
<br>def tnid_graphql_request(query, variables=None):
<br> endpoint = 'https://api.tnid.com/graphql'
<br> headers = {
<br> 'Content-Type': 'application/json',
<br> 'Authorization': f'Bearer {YOUR_API_TOKEN}'
<br> }
<br>
<br> payload = {
<br> 'query': query,
<br> 'variables': variables or {}
<br> }
<br>
<br> response = requests.post(endpoint, json=payload, headers=headers)
<br> return response.json()
<br>```
<br>
<br><h2 class="mt-5 mb-3"> Common GraphQL Queries
<br>
<br><h2 class="mt-5 mb-3"># 1. Retrieve User Identity
<br>```python
<br>def get_user_identity(user_id):
<br> query = '''
<br> query GetUserIdentity($userId: ID!) {
<br> getUserIdentity(id: $userId) {
<br> id
<br> email
<br> verified
<br> authenticationMethods
<br> }
<br> }
<br> '''
<br> variables = {'userId': user_id}
<br> return tnid_graphql_request(query, variables)
<br>```
<br>
<br><h2 class="mt-5 mb-3"># 2. Create User Authentication
<br>```python
<br>def create_user_auth(email, password):
<br> query = '''
<br> mutation CreateUserAuth($input: UserAuthInput!) {
<br> createUserAuthentication(input: $input) {
<br> token
<br> userId
<br> success
<br> }
<br> }
<br> '''
<br> variables = {
<br> 'input': {
<br> 'email': email,
<br> 'password': password
<br> }
<br> }
<br> return tnid_graphql_request(query, variables)
<br>```
<br>
<br><h2 class="mt-5 mb-3"> Best Practices
<br>
<br>1. <strong>Error Handling<strong>: Always implement robust error checking
<br>2. <strong>Secure Token Management<strong>: Never hardcode API tokens
<br>3. <strong>Rate Limiting<strong>: Respect API call limits
<br>4. <strong>Caching<strong>: Implement appropriate caching strategies
<br>
<br><h2 class="mt-5 mb-3"> Example Use Case
<br>
<br>```python
<br>def authenticate_and_get_profile():
<br> try:
<br> # Authenticate user
<br> auth_result = create_user_auth('user@example.com', 'secure_password')
<br>
<br> if auth_result['data']['createUserAuthentication']['success']:
<br> user_id = auth_result['data']['createUserAuthentication']['userId']
<br>
<br> # Fetch user identity
<br> user_identity = get_user_identity(user_id)
<br> return user_identity
<br>
<br> except Exception as e:
<br> print(f"Authentication failed: {e}")
<br>```
<br>
<br><h2 class="mt-5 mb-3"> Conclusion
<br>
<br>TNID's GraphQL APIs provide a flexible and powerful way to manage digital identities. By following these patterns, you can create robust authentication and identity management solutions in Python.
