pytekmomoapi.

An Opinionated Python SDK for the for the MTN Mobile Money API. The goal of this SDK library is to enable python developers implement MTN Mobile Money APIs in a flexible, yet consistent manner.

The Open API is a JSON REST API that is used by Partner systems to access services in the Wallet platform. The Open API exposes services that are used by e.g. online merchants for managing payments and other financial services.

Building from Source for Developers

$ cd pytekmomoapi
$ python setup.py install

Quickstart

Installation

pip install pytekmomoapi

Sandbox User Provisioning

We have provided a convenient function, tekmomoapi.get_user_id_and_api_key , to help you quickly provision and get the required credentials i.e the user_id and apiKey on the sandbox environment.

The Library also provided a utility function to get a random uuid.uuid4 string, this is quite useful because the remote Momo Developer API heavily uses uuid4s for identification and referencing, i.e during user provisioning, financial transactions, party identification and referencing. The function tekmomoapi.get_random_uuid_str provides that convenience.

This reduces the amount of boilerplate code that would be otherwise required.

Example

import tekmomoapi
creds=dict(
   collection_subscription_key="3265aef9928c259a31b44faf812dc2da",
   remittance_subscription_key="928c259a31b44faf812dc2da3265aef9",
   disbursement_subscription_key="31b44faf812dc2da928c259a3265aef9",
)
cuser = tekmomoapi.get_user_id_and_api_key(
    creds.get("collection_subscription_key"))

duser = tekmomoapi.get_user_id_and_api_key(
    creds.get("disbursement_subscription_key"))

user = tekmomoapi.get_user_id_and_api_key(
   creds.get("remittance_subscription_key"))

    user = tekmomoapi.get_user_id_and_api_key(creds.get("remittance_subscription_key"))
    print(user)
    {'user_id': 'fcbf0091-2dbe-4f37-9131-46a2a0dcda9e', 'apiKey': 'cb196acfa75b4bf1858b5dccdbb605a6'}

Authentication and Authorization

OAuth Token is generated from the merchants' API Key and Secret. The API Key and API Secret can be obtained through the provisioning API in Sandbox.

We have built-in the authentication and authorization processes so you dont have to worry about base64 encodings, whether to user Bearer or Basic Authentication, enabling you to focus on more important details i.e your business logic implementation and other more fun stuff.

You can obtain the authentication header string anytime if you wish to do so by using the top level tekmomoapi.scaffold.BaseAPI{.pycode .python} and its subclassess tekmomoapi.scaffold.BaseAPI.basic_auth_str or the tekmomoapi.scaffold.BaseAPI.bearer_auth_str property methods.

Example

RemAPI = tekmomoapi.RemittanceAPI(
    creds.get("remittance_subscription_key"),
    base_url=tekmomoapi.SANDBOX_BASE_URL,
    **user,
)
DisAPI = tekmomoapi.DisbursementAPI(
    creds.get("disbursement_subscription_key"),
    base_url=tekmomoapi.SANDBOX_BASE_URL,
    **duser,
)
ColAPI = tekmomoapi.CollectionAPI(
    creds.get("collection_subscription_key"),
    base_url=tekmomoapi.SANDBOX_BASE_URL,
    **cuser,
)
print("Remittance Basic Auth str: ",RemAPI.basic_auth_str)
print("Collection Bearer Auth str: ",ColAPI.bearer_auth_str)
print("Disbursement Basic Auth str: ",DisAPI.basic_auth_str)
print("Disbursement Bearer Auth str: ",DisAPI.bearer_auth_str)

Account Balance and Account Holder Validation

All Subclasses of tekmomoapi.scaffold.BaseAPI provide a method for checking the account balance of the respective concrete API as well a method for checking whether an account id or PartyId is active and valid.

Example

print(
    f"ColAPI.get_account_balance: {ColAPI.get_account_balance('sandbox')}")
rembal=RemAPI.get_account_balance()
disbal=DisAPI.get_account_balance(x_target_environment="sandbox")
# print(rembal)
# print(disbal)
# Check if Account is Active
tmsisdn = "22997108557"
ColAPI.is_account_active(tmsisdn, 'msisdn', 'sandbox')
True
RemAPI.is_account_active(tmsisdn, 'msisdn',
'sandbox')
True
DisAPI.is_account_active(tmsisdn, 'msisdn', 'sandbox')
True

ColAPI.get_account_balance: {'availableBalance': '1000', 'currency': 'EUR'}

Collections API

The CollectionAPI provides a method for requesting payments from customers as well as a method for checking the status of a payment request in addition to the aforementioned account balance and validation methods defined in the BaseAPI base class.

The CollectionAPI uses the CParty and PaymentRequest types for its PaymentRequest and Party object arguments.

The tekmomoapi.get_collection_party_obj and tekmomoapi.get_payment_request_obj provide convenience function to create the required Party and Transfer objects.

Example

Create a Collection PaymentRequest Object using the convenience functions.

payment_request_obj = tekmomoapi.get_payment_request_obj(
    amount="100",
    currency="EUR",
    externalId=get_random_uuid_str(),
    payer=tekmomoapi.get_collection_party_obj(
        "msisdn", "22997108557").to_jsonable(),
    payerMessage="Payment Request Message Here",
    payeeNote="Customer Note Here",
)

Request Payment

Using the payment_request_obj in the example above, we can request payment from a customer using the tekmomoapi.CollectionAPI.request_payment function.

ColAPI.request_payment(
    payment_request_obj.externalId,
    payment_request_obj,
    x_callback_url=None,
    x_target_environment="sandbox",
)
# Check Payment Request Status
print(ColAPI.get_payment_request_status(payment_request_obj.externalId))

{"amount": "100", "currency": "EUR", "financialTransactionId": "454621636",
"externalId": "8b2e92fd-a9a6-48e1-bae5-099d5d3ad4c8", "payer": {"partyIdType":
"MSISDN", "partyId": "22997108557"}, "payerMessage": "Payer Message Here",
"payeeNote": "Payee Note Here", "status": "SUCCESSFUL"}

Disbursements API

The DisbursementAPI provides a method for initiating transfers from the business to other parties as well as a method for checking the status of a transfer request in addition to the account balance and validation methods defined in the base class BaseAPI.The DisbursementAPI uses the DTransfer and DParty classes to specify its Party and Transfer object arguments.

The tekmomoapi.get_disbursement_obj and tekmomoapi.get_disbursement_party_obj provide convenience functions to create the correct and desired Transfer and Party objects.

Example

Create a Disbursement Transfer Object using the convenience functions.

dtransfer_obj = tekmomoapi.get_disbursement_transfer_obj(
    amount="100",
    currency="EUR",
    externalId=get_random_uuid_str(),
    payee=tekmomoapi.get_disbursement_party_obj(
        "msisdn", "22997108557"
    ),  # .to_jsonable(),
    payerMessage="Disbursement Transfer Message Here",
    payeeNote="Payee Business Note Here",
)

Transfer Funds

Using the dtransfer_obj in the example above, we can transfer funds using the tekmomoapi.DisbursementAPI.transfer function.

dtres = DisAPI.transfer(
    dtransfer_obj.externalId,
    dtransfer_obj,
    x_callback_url=None,
    x_target_environment="sandbox",
)
# Check Transaction Status
print(DisAPI.get_transfer_status(dtransfer_obj.externalId))

{"amount": "100", "currency": "EUR", "financialTransactionId": "1501780124",
"externalId": "f832c026-fd6a-4414-9660-df3080471bdf",
"payee": {"par
