Subject: B2B Push PO API — endpoints returning empty 200 responses (sandbox key)

Hi,

We've finished building our side of the B2B Push PO integration against the
Partner Integration Guide (v1.0, 2026-06-08) and started testing with our
sandbox key, but every endpoint on https://b2b.pamsauto.com is returning
HTTP 200 with an EMPTY body (content-length: 0) instead of JSON.

This includes cases that per the guide should return errors:

  - POST /B2BPushPO.ashx with a valid sandbox key and a valid PO body
    -> 200, empty (expected: workOrderNumber JSON)
  - POST /B2BPushPO.ashx with an invalid key
    -> 200, empty (expected: 401 UNAUTHORIZED)
  - POST /B2BPushPO.ashx with a malformed body
    -> 200, empty (expected: 400 BAD_REQUEST)
  - GET /B2BPushPOStatus.ashx?workOrder=1
    -> 200, empty
  - POST /DoesNotExist.ashx (bogus path)
    -> 200, empty

Since even a non-existent path responds the same way, it looks like the
B2BPushPO handlers aren't deployed/routed on the server yet and a catch-all
is swallowing the requests.

Example request for your server-side logs (you mentioned you log every
request): 2026-06-10 04:36:15 GMT, response header
x-stackifyid: V2|6f09cdbf-a03a-423d-90d2-7f7a7b0a2925|C75694|CD4
Sample PO body we pushed:
{"poNumber":"GP-TEST-PROBE-1","shipTo":{"name":"Ruthie Mich","street1":"1120 Us Highway 70 Se","street2":null,"city":"Hickory","state":null,"zip":"28602","phone":"+18283450777"},"lineItems":[{"inventoryId":5207656,"stockTicketNumber":"GG0757","unitPrice":85}]}

Could you check the deployment? We're ready to test as soon as the endpoints
respond — our system already retries automatically every 15 minutes.

Thanks,
Go-Parts
