Leveraging TNID GraphQL APIs: A Comprehensive Guide for Python Developers
October 29, 2025
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.
## Getting Started with TNID GraphQL
### Prerequisites
- Python 3.7+
- `requests` library
- TNID API credentials
### Installation
```python
pip install requests
```
## Authenticating GraphQL Requests
```python
import requests
def tnid_graphql_request(query, variables=None):
endpoint = 'https://api.tnid.com/graphql'
headers = {
'Content-Type': 'application/json',
'Authorization': f'Bearer {YOUR_API_TOKEN}'
}
payload = {
'query': query,
'variables': variables or {}
}
response = requests.post(endpoint, json=payload, headers=headers)
return response.json()
```
## Common GraphQL Queries
### 1. Retrieve User Identity
```python
def get_user_identity(user_id):
query = '''
query GetUserIdentity($userId: ID!) {
getUserIdentity(id: $userId) {
id
email
verified
authenticationMethods
}
}
'''
variables = {'userId': user_id}
return tnid_graphql_request(query, variables)
```
### 2. Create User Authentication
```python
def create_user_auth(email, password):
query = '''
mutation CreateUserAuth($input: UserAuthInput!) {
createUserAuthentication(input: $input) {
token
userId
success
}
}
'''
variables = {
'input': {
'email': email,
'password': password
}
}
return tnid_graphql_request(query, variables)
```
## Best Practices
1. **Error Handling**: Always implement robust error checking
2. **Secure Token Management**: Never hardcode API tokens
3. **Rate Limiting**: Respect API call limits
4. **Caching**: Implement appropriate caching strategies
## Example Use Case
```python
def authenticate_and_get_profile():
try:
# Authenticate user
auth_result = create_user_auth('user@example.com', 'secure_password')
if auth_result['data']['createUserAuthentication']['success']:
user_id = auth_result['data']['createUserAuthentication']['userId']
# Fetch user identity
user_identity = get_user_identity(user_id)
return user_identity
except Exception as e:
print(f"Authentication failed: {e}")
```
## Conclusion
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.
