help help

This endpoint (/requesttowithdraw/x-reference-id) returns a forbidden (403) error on every request

Every request to the deposit endpoint returns a "Forbidden" error (status code : 403) even though i have created valid api user and key on my portal. The api user and key works fine for the request withdrawal though and can even generate a disbursement token successfully. The only prolem is with the forbidden response from the deposit endpoint
