Dear MTN Mobile Money Team, I hope you are doing well. My name is Maurice, and I am the founder of Bank of West Africa (BWA), a digital-first financial platform currently in the process of integrating with the MTN MoMo Open API for collections, disbursement, and remittance services. We are excited about the opportunity to partner with MTN Mobile Money and bring enhanced financial access across West Africa. However, while reviewing the onboarding documentation and requirements, we encountered a few areas where the current forms and questionnaires appear to be structured primarily for traditional merchants, agents, or remittance operators. Bank of West Africa operates as a fintech platform offering: - Digital banking services- Mobile wallet infrastructure- QR code payments- Virtual cards- Remittance and cross-border transactions- Bill payments and mobile top-ups- Installment-based financial services As such, some sections of the Merchant Application Form, KYC requirements, and AML questi

Hi Team,I am currently developing a recurring payment solution using the MoMo API (Ghana environment) and would like to clarify the expected behavior for pre-approval mandates to ensure a smooth user experience.1. Renewing Active Mandates:If an MSISDN already has an active pre-approval mandate, what happens if a second POST /preapproval request is sent to that same number before the current one expires?Does the new request overwrite the existing one and reset the validityTime? Does it return a PREAPPROVAL_EXIST_PENDING error even if the previous mandate is already in a SUCCESSFUL state? Is there a recommended way to "extend" a mandate without requiring the customer to perform a fresh approval?2. Maximum validityTime Constraints:Regarding the validityTime parameter in the POST /preapproval payload:What is the maximum allowable value (in seconds) for this field in the Ghana Production environment? Are there platform or regulatory caps (e.g., 365 days) that would cause a validation error

Issue 1: Cannot Create New Pre-Approval After ExpiryDescription:After a pre-approval mandate expires, attempts to create a new pre-approval for the same MSISDN consistently fail.Steps to Reproduce:Create a pre-approval mandate for an MSISDN.Allow the pre-approval to expire.Attempt to create a new pre-approval mandate for the same MSISDN.Actual Result:The request fails with the following response:{  "message": "Preapproval already exist and is in pending state",  "code": "PREAPPROVAL_EXIST_PENDING"}Despite this, the MSISDN holder still receives an STK Push to approve the transaction,when a normal request to pay is initiated on the MSISDN which suggests the previous pre-approval is no longer active.Expected Result:Once a pre-approval has expired, the system should allow the creation of a new pre-approval mandate for the same MSISDN.Issue 2: Get Approved Pre-Approvals Endpoint Not SupportedDescription:The Get Approved Pre-Approvals API is not supported in the Ghana target environment.Step
