No callback received after successful payment request

Hello support, 
There are difficulties with going through the payment async flow before we are ready to go live.

What I did:
1. Subscribed  “Collection” API group.
2. Generated userId = uuid_v4
3. And created user via “/v1_0/apiuser” with “Ocp-Apim-Subscription-Key” header value = subscribed collections primary key with body:
{"providerCallbackHost": "our-company-domain-host"} // without scheme
4. Created userKey via “/v1_0/apiuser/{userId}” with the same “Ocp-Apim-Subscription-Key” header
5. Created accessToken via “/collection/token/”
6. Requested “/collection/v1_0/requesttopay” with headers:
Ocp-Apim-Subscription-Key: profile->subscribed collections primary key
X-Reference-Id: f0b06fb7-4e7c-462b-9e29-d62b6b2f17cd
X-Target-Environment: sandbox
X-Callback-Url: http://our-company-domain-host/momo/payment/purchase-callback
Content-Type: application/json
Authorization: Bearer token from step-5
and body:
  "amount": "100.00",
  "currency": "EUR",
  "externalId": "f0b06fb7-4e7c-462b-9e29-d62b6b2f17cd",
  "payer": {
    "partyIdType": "MSISDN",
    "partyId": "233123456789"
and payment created with http status: 202 Accepted
7. Our REST service also listened for both PUT and POST in /momo/payment/purchase-callback, but unfortunately nothing happend.
What could have happened here and what should we do? Unlucky we can't see any information belonging to this part of flow.​​​​​​​

On Sandbox the callbacks are intermittent, please proceed with the testing.

The Callbacks are working fine in Production.

The structure for the callback response is the same as the one from Get Status API response. 

Ok, got it
