MoMoPSBAPI Python SDK Documentation

Welcome to the MoMoPSBAPI Python SDK! This SDK enables developers to integrate with the MTN MoMo API for managing API users, API keys, OAuth 2.0 tokens, and payment processing in a seamless manner. Below, you'll find a comprehensive guide on installation, usage, and functionality.

---

Features

• Create and manage API Users
• Generate API Keys for secure communication
• Obtain OAuth 2.0 tokens for authentication
• Initiate and manage payment requests
• Validate API responses

---

Requirements

Sandbox/Testing Users:

1. MTN MoMo Developer Account: # Here
2. Collection and Disbursement subscription keys

Production Users:

1. Collection and Disbursement subscription keys
2. API User ID and API Key

---

Installation

Install the required dependencies:

pip install momo-psb

---

Quickstart Guide

Initialize the SDK

from momo_psb import MoMoPSBAPI

# Replace with your details
BASE_URL = "https://sandbox.momodeveloper.mtn.com"
SUBSCRIPTION_KEY = "your_subscription_key"

# Initialize the API client
api = MoMoPSBAPI(base_url=BASE_URL, subscription_key=SUBSCRIPTION_KEY)

---

Key API Operations

1. Create API User

Generate a unique API User.

import uuid

reference_id = str(uuid.uuid4())  # Generate a unique reference ID
callback_host = "https://your-callback-host.com"

response = api.create_api_user(reference_id, callback_host)
print("Status Code:", response.status_code)
print("Response:", response.json())

2. Generate API Key

Create an API Key for the generated API User.

api_user = "your_api_user_id"
response = api.create_api_key(api_user)
print("Status Code:", response.status_code)
print("API Key:", response.json().get("apiKey"))

3. Retrieve API User Details

Fetch details of an API User.

response = api.get_api_user_details(api_user)
print("Status Code:", response.status_code)
print("User Details:", response.json())

4. Obtain OAuth 2.0 Token

Generate an access token for authorization.

api_key = "your_api_key"
response = api.get_oauth_token(api_user, api_key)
print("Status Code:", response.status_code)
token_data = response.json()
access_token = token_data.get("access_token")
print("Access Token:", access_token)

5. Request to Pay

Initiate a payment request from a consumer.

payer_info = {
    "partyIdType": "MSISDN",
    "partyId": "+2348056042384"
}
reference_id = str(uuid.uuid4())

response = api.request_to_pay(
    reference_id=reference_id,
    access_token=access_token,
    amount="100.00",
    currency="EUR",
    external_id=str(uuid.uuid4()),
    payer=payer_info,
    payer_message="Payment for services",
    payee_note="Thank you for your payment"
)

print("Status Code:", response.status_code)
print("Response:", response.json())

---

Error Handling

Use the validate_response method to handle errors gracefully.

try:
    data = api.validate_response(response)
    print("Success:", data)
except Exception as e:
    print("Error:", e)

---

Notes

1. Environment Setup:
   • Default environment is sandbox. Update the base URL for production use.
2. Status Codes:
   • 200, 201, 202: Successful operations.
   • Other codes indicate errors and should be handled appropriately.
3. Unique Identifiers:
   • Use uuid.uuid4() to generate reference IDs for requests.
