Subject: Error SC: 207, EC: 30185000 on 3DS Init API (Sandbox) - Previously Working

Hi all,

I am currently testing the 3DS integration in the Sandbox environment and have run into a roadblock with the v2/.../3ds/init endpoint. This exact flow was working successfully last week, but now I consistently receive an SC: 207 error.

For this test, I am using the first Visa card from the 3DS test cards list provided in your documentation.

Here are the exact steps and payloads I am using:

Step 1: Create Account (Success)
I am able to successfully create the account and receive an accountID. The card token was generated from the iframe.

curl --request POST \
  --url https://api.sandbox.tabapay.net:10443/v1/clients/[REDACTED_CLIENT_ID]/accounts \
  --header 'accept: application/json' \
  --header 'authorization: Bearer [REDACTED_BEARER_TOKEN]' \
  --header 'content-type: application/json' \
  --data '{
  "referenceID": "Unique_refID123",
  "card": {
    "token": "[REDACTED_CARD_TOKEN]"
  },
  "owner": {
    "name": {
      "first": "Test",
      "middle": "D",
      "last": "Name"
    },
    "address": {
      "line1": "123 Street",
      "city": "San Francisco",
      "state": "CA",
      "zipcode": "94103",
      "country": "840"
    }
  }
}'

Step 2: 3DS Init (Failure)
When passing the newly generated accountID into the V2 3DS Init endpoint, the request fails.

curl --request POST \
  --url https://api.sandbox.tabapay.net:10443/v2/clients/[REDACTED_CLIENT_ID]/3ds/init \
  --header 'accept: application/json' \
  --header 'authorization: Bearer [REDACTED_BEARER_TOKEN]' \
  --header 'content-type: application/json' \
  --data '{
  "account": {
    "accountID": "[REDACTED_ACCOUNT_ID]"
  },
  "order": {
    "orderID": "1233order",
    "amount": "0.00"
  }
}'

This code was working perfectly up until last week. I have already tried testing with multiple different parameters (such as varying the transaction amounts, and trying different test cards), but I consistently get the same error. Could you let me know what EC: 30185000 means and what I need to do to fix it? Any guidance would be greatly appreciated!
