Which MOMO API website should we be using

I’ve been using https://momodeveloper.mtn.com/ and recently I came accross https://momoapi.mtn.com/And generally they do the exact things, except you’ll have to create a new account, which I did but they are taking too long to approve my product(Collections and Disbursement) subscriptions which makes me wonder if the site is still operational.Any answers will be much appriciated. Thanks.

Where Can I find the Subscription Key in Sandbox.

Hi, I am Certified Salesforce Developer and looking to integrate salesforce with MTN momo through rest API. For initial Stages I am testing it in Sandbox and testing it in Postman about how the things are working.I have got 2 keys in my Profile Primery Key and Secondary Key. Whenever I try to generate an access token in POST man it says :{    "statusCode": 401,    "message": "Access denied due to invalid subscription key. Make sure to provide a valid key for an active subscription."}I have tried adding both keys in header with parameter : Ocp-Apim-Subscription-Key = Key.I have subscriped the collection widget. IS the integration possible with salesforce?

How can the API allow person to person transfers?

Hello 🤗I want to implement the scenarios bellow, can you suggest for me the right endpoints:Transfer money from user account to his friend. Transfer money from user account to business accounts of some service providers (to pay a bill or any another service).I want to use CreateInvoice for both of cases, will it work? because the friend account is not for business, will this provide and error? does mtn make a difference between a merchant or a personal account?and what endpoints do you suggest for me.@byaruhaf @anicet @crankluga @allan.ddamulira @leontymo I would appreciate if you help me 🙏

GetAccountBalance Endoint

Good day team,I am completing the UAT test cases excel document for Collection. I have all other cases completed except the one for insufficient funds, i.e. sending a debit amount greater than Payer available balance. Because I do not know the balance I have, I decided to call the GetAccountBanlance end point. Unfortunately I am getting status 500 (internal server error), with the message “Authorization failed. Insufficient permissions.”Any assistance to point me to what I am not doing right.Thanks

Remittance: C2C

Good morning MTN community 😊I want to use Remittance product to allow my app users to transfer money to their friends.I got confused about which endpoint to use, cashTransfer or Transfer.in the transfer request body the sender is not mentioned, therefor the sender is my application account not my user’s account right? in cashTransfer, are the funds transfered from the mtn mobile money account or in cash? and can you give me an example of values of the following attributes please? { "orginatingCountry": "string", "originalAmount": "string", "originalCurrency": "string", "payerIdentificationType": "PersonIdentificationType1Code", "payerIdentificationNumber": "string", "payerIdentity": "string", "payerLanguageCode": "string", "payerMsisdn": "string (Msisdn)", "payerGender": "string"} Thank you for your help. @crankluga @allan.ddamulira @anicet @Maxie @Lubunde Job

Authorisation

Good morning team, I hope you are doing great. I am having some concerns if you can help me:What is the role of bc-authorize and CreateOauth2Token ? (I didn’t understand how it happens in real time, or what is its use).what is the difference between CreateOauth2Token and CreateAccessToken?Why do I need bc-authorize and CreateOauth2Token if I can make my requests only with CreateAccessToken?
