Hello, I encountered the same issue. I wonder, if the sandbox mode does not support any african currency? I tried with “XOF” and i got the same error currency not supported.

Sandbox only supports EUR, the country specific currencies like UGX, XOF etc are for production.

Hello everyone,

I have a question regarding the integration of MTN MoMo for a client who operates in two different countries: Tanzania and Eswatini.

I would like to understand whether the client would need separate credentials for each country, since the payment environments may differ by market. In other words, should the integration use country-specific API users and credentials, or can the same credentials work across multiple MTN MoMo markets?

Additionally, the client intends to process payments in TZS (Tanzanian Shilling) and SZL (Swazi Lilangeni). Are there any specific configuration requirements or limitations when working with multiple currencies across different MTN MoMo markets?

Any clarification or guidance on the recommended approach for this scenario would be greatly appreciated.

Thank you.
