MoMo API Upgrade - One API The MoMo API Platform is being enhanced to strengthen security, standardisation, monitoring, and operational efficiency. As part of these improvements, three mandatory implementation changes are being introduced, which all partners must implement, validate, and complete within the prescribed timelines.Credential Migration (New User ID & Credential Token) Token Generation Changes (Mandatory X-Target-Environment Header) Base URL ChangesThese are the primary areas that should be validated during partner readiness.  Key Message for Partners The MoMo API platform enhancement requires partners to update their base URL from https://proxy.momoapi.mtn.com or https://ericssonbasicapi1.azure-api.net to the new MoMo API base URL: https://momoapi.momo.africa. API endpoints, business functionality, request payloads, and response structures remain unchanged. Partners are also required to update their credentials by:Replacing the API User with the UserID. Replacing the API Key with the Credential Token. Additionally, partners must review their Access Token generation requests and ensure that the now-mandatory X-Target-Environment header is included. Follow Guide below to generate your new set of credentials.Guide for Generating UserId and Credential Token Credential Update What changes Partners must replace the existing API User and API Key used for token generation with new credentials generated from the Partner Portal. Link for the country specific Partner Portal can be attained by reaching to your account manager or relationship manager:User ID (Identity) Credential Token (Password)After migration, the existing API User/API Key credentials will no longer be valid for authentication on the new platform. Before upgradePartner uses:API User = 12345678-abcdAPI Key = abcxyz987654Authentication:base64(API_USER:API_KEY)Example:Authorization: Basic base64(12345678-abcd:abcxyz987654) After upgradePartner generates new credentials from the Partner Portal:User ID = user_12345Credential Token = token_987654321Authentication:base64(USER_ID:CREDENTIAL_TOKEN)Example:Authorization: Basic base64(user_12345:token_987654321) Token Generation Changes What changes The Create Access Token endpoint remains the same, but the authentication details and required headers change as follows:  Component Before After Authorization Secret API Key Credential Token X-Target-Environment Optional Mandatory Subscription Key Required No Change  Before upgradePOST /collection/tokenAuthorization: Basic base64(API_USER:API_KEY)Ocp-Apim-Subscription-Key: SUBSCRIPTION_KEYExample:POST https://proxy.momoapi.mtn.com/collection/tokenAuthorization: Basic base64(12345678-abcd:abcxyz987654)Ocp-Apim-Subscription-Key: 123456789 After upgradePOST /collection/tokenAuthorization: Basic base64(USER_ID:CREDENTIAL_TOKEN)Ocp-Apim-Subscription-Key: SUBSCRIPTION_KEYX-Target-Environment: mtnugandaExample:POST https://momoapi.momo.africa/collection/tokenAuthorization: Basic base64(user_12345:token_987654321)Ocp-Apim-Subscription-Key: 123456789X-Target-Environment: mtnuganda NOTE: The X-Target-Environment, is currently being passed in other API calls and is country specific. Please maintain the same value you are using for the other API calls e.g mtnuganda, mtnghana, mtncameroon etc Base URL Changes What changes Partners must update the base URL used for all API requests as part of the migration to the new MoMo API environment.✅ API endpoints remain unchanged.✅ Request and response payloads remain unchanged.✅ Only the hostname/base URL changes.  Before upgrade : MoMo APIAll integrations point to:https://proxy.momoapi.mtn.com or https://ericssonbasicapi1.azure-api.netExamples:POST https://proxy.momoapi.mtn.com/collection/tokenPOST https://proxy.momoapi.mtn.com/collection/v1_0/requesttopayGET https://proxy.momoapi.mtn.com/collection/v1_0/requesttopay/{referenceId} After upgrade: New MoMo API environmentAll integrations must be updated to:https://momoapi.momo.africaExamples:POST https://momoapi.momo.africa/collection/tokenPOST https://momoapi.momo.africa/collection/v1_0/requesttopayGET https://momoapi.momo.africa/collection/v1_0/requesttopay/{referenceId} Before vs after comparison Component Before After Base URL https://proxy.momoapi.mtn.com https://momoapi.momo.africa /collection/token https://proxy.momoapi.mtn.com/collection/token https://momoapi.momo.africa/collection/token /collection/v1_0/requesttopay https://proxy.momoapi.mtn.com/collection/v1_0/requesttopay https://momoapi.momo.africa/collection/v1_0/requesttopay API Payloads No Change No Change API Headers Updated as per migration requirements Updated as per migration requirements Business Functionality No Change No Change  Example upgrade configurationCurrent Configuration{"baseUrl": "https://proxy.momoapi.mtn.com"}New Configuration{"baseUrl": "https://momoapi.momo.africa"} Country/OPCO Migration Status Country Live on new Platform Congo Brazzaville Live Liberia Live Uganda Live Eswatini Live Ivory Coast Live Benin Live Cameroon InProgres Ghana InProgres Zambia InProgres South Africa InProgres Rwanda InProgres Nigeria InProgres South Sudan InProgres  NOTE: For OPCOs/Countries inProgress, please reach out to your OPCO Account Manager for confirmation on GoLive Date. Support Channels Partners can use the following channels for  support, technical guidance, and community-based learning during the transition to the new MoMo API platform.Email support: Send queries, migration issues, and technical support requests to support.momodeveloper@mtn.com.

Part of our ongoing efforts to improve MoMo Open API experience, we have updated the reason field for some FAILED responses on the Get Status API with insightful descriptions as illustrated below. {"externalId": "c1f4687688585858a173f12",    "amount": "500",    "currency": "UGX",    "payer": {        "partyIdType": "MSISDN",        "partyId": "25677000000"    },    "payerMessage": "Debit RequesttoPay",    "payeeNote": "Debit  RequesttoPay",    "status": "FAILED",    "reason": "NOT_ENOUGH_FUNDS"} Use Case Product Actual Reason Insufficient Funds Collections NOT_ENOUGH_FUNDS Insufficient Funds Disbursements NOT_ENOUGH_FUNDS Transaction Time out due to not inputting the PIN Collections COULD_NOT_PERFORM_TRANSACTION Invalid Payer Number Collections PAYER_NOT_FOUND Invalid Payee Number Disbursements PAYEE_NOT_FOUND Transaction Limit Exceeded for Payer Collections PAYER_LIMIT_REACHED Transaction Limit Exceeded for Receiver Disbursements NOT_ENOUGH_FUNDS Blocked Payer Account Collections SENDER_ACCOUNT_NOT_ACTIVE Blocked Payee Account Disbursements PAYEE_NOT_ALLOWED_TO_RECEIVE Blocked Partner Account Collections NOT_ALLOWED Blocked Partner Account Disbursements NOT_ALLOWED  

 When querying for the status of a financial transaction, the result can either be SUCCESSFUL, FAILED, or PENDING. A successful outcome means the MoMo subscriber has authenticated the transaction with the correct PIN, whereas a pending status means the MoMo subscriber is yet to approve the transaction with their PIN.Although the labels 'successful' and 'pending' are self-explanatory, a failed response could be due to a variety of factors, such as the customer entering an incorrect PIN or their wallet lacking sufficient funds to finalize the transaction.Developers have experienced difficulty understanding some of these error messages, particularly the INTERNAL_PROCESSING_ERROR which is a generic encompassing numerous errors with the most prevalent being a lack of sufficient funds in the MoMo subscriber's wallet.To address this issue, our team has devised a revised error response procedure that will provide specific reasons for failure, such as insufficient funds.This revision process is ongoing and developers who are part of our community platform will receive regular updates on these errors as they are implemented.Please note that while HTTP Codes remain unchanged, reasons for failure will be included in the response body by the team.Generic {    "externalId": "04822b2a-0896-4612-9e9e-15ce749b7883",    "amount": "500000000",    "currency": "UGX",    "payer": {        "partyIdType": "MSISDN",        "partyId": "25677000000"    },    "payerMessage": "test",    "payeeNote": "test",    "status": "FAILED",    "reason": "INTERNAL_PROCESSING_ERROR"}From the Snipped, the Reason field will be updated only.
