## How did you test it?

When we hit this URL the email is sent to biz@hyperswitch.io so to restrict the unnecessary test mails added some checks.
```
curl --location 'http://localhost:8080/user/data' \
--header 'api-key: hyperswitch' \
--header 'Content-Type: text/plain' \
--header 'Authorization: Bearer JWT' \
--data-raw '{
    "ProdIntent": {
        "poc_email": "---",
        "is_completed": true,
        "legal_business_name": "---",
        "business_location": "AX",
        "business_website": "---",
        "poc_name": "---",
        "comments": "---"
    }
}'
```
