Hi everyone, We're using Instant Inventory JSON feed for custom app that daily check catalog / reservations. App makes requests as described here: http://technet.rapaport.com/Info/RapLink/Format_Json.aspx http://technet.rapaport.com/Info/RapLink/SampleCode/JSON_CodeSample.aspx Though format is `applciation/json` we're using `application/x-www-form-urlencoded` as described in the last link. Recently, we started to get "1001 Invalid format" errors. On March, 31, we were unable to sync diamonds.
The request is as follows: ```json { "request": { "header": { "username": "***", "password": "***" }, "body": { "search_type": "White", "shapes": ["round","princess","emerald","radiant","cushion","pear","marquise","oval","asscher","heart"], "fluorescence_intensities": ["none","faint","medium","strong","very strong"], "size_to": 9.98, "size_from": 0.18, "color_from": "D", "color_to": "M", "clarity_from": "IF", "clarity_to": "I1", "cut_from": "Excellent", "cut_to": "Fair", "polish_from": "Excellent", "polish_to": "Fair", "symmetry_from": "Excellent", "symmetry_to": "Fair", "table_percent_from": "0", "table_percent_to": "100", "depth_percent_from": "0", "depth_percent_to": "100", "labs": ["GIA"], "price_total_from": 400, "price_total_to": 5000000, "page_number": 0, "page_size": 50, "sort_by": "Price", "sort_direction": "ASC" } } } ```
This was working for several years, but now there's an error with no details.
Could you please specify what changed in API and how should we make the request?
Thank you.

I also see that all individual diamonds I've checked with Single Diamond Endpoint have 3001 error https://technet.rapaport.com/HTTP/JSON/RetailFeed/GetSingleDiamond.aspx
[NullReferenceException: Object reference not set to an instance of an object.]

Even without all optional params request returns 1001 Invalid format ```json { "request": { "header": { "username": "***", "password": "***" }, "body": { "page_number": 1, "page_size": 50 } } } ``` Response: ```json { "response": { "header": { "error_code": 1001, "error_message": "Invalid format" }, "body": {} } } ```

Hi Dmitri

Hi, Our RapNet ID is 19849. Tried to run request again -- still the same error. Also tried to run request with parameters similar to the message below -- same error too. Hmm. Let me know if there's something with our account, I can talk with management if some additional actions/subscriptions needed for our account. Thank you for quick response!

Please check your end points
The endpoints should be
https://technet.rapaport.com/HTTP/JSON/RetailFeed/GetDiamonds.aspx
and not
http://technet.rapaport.com/HTTP/JSON/RetailFeed/GetDiamonds.aspx
Thanks
No

Hi, just checked, we use secure (https) endpoints. Fetches made with GuzzleHttp library, which works around cURL. In short, code looks like this: $client = new GuzzleHttp\Client();
$diamondsResponse = $client->post(
'https://technet.rapaport.com/HTTP/JSON/RetailFeed/GetDiamonds.aspx',
array(
'headers' => array(
'Content-Type' => 'application/x-www-form-urlencoded'
),
'body' => $rawRequest
)
);
Where $rawRequest is raw JSON body. I also making requests from Postman 2 app, but having the same responses.

Hi! Thank you for sending Postman request info. I believe I adjusted couple of fixes and used wrong code for testing (tried to reach page 0, where page starts at 1). Right now by checking logs on our production server I see that request were stopped with message "User is sending too many requests". I believe it's some kind of request limiter here. Could you specify or email me with information about request limiting, so we can adjust our software to have a timeout before next request? Best Regards

Also, could you please specify which error code is returned with "User is sending too many requests". Unfortunately I can't really always reproduce the error as the request limiting seems to be quite soft, so in order to handle such errors and make a delay before retry I would like to match error code to retry diamonds fetching. Best Regards
