DXS Documentation

What is DXS RCD API?

DXS RCD API is a REST API that makes accessible the event-level data records for HME CLOUD connected timers (ZOOM and Nitro). The intended use is to provide short term access to detailed timing records for retrieval and insertion into a local database for business analytics use. It is not intended to be used as the back-end data storage or database source for those business analytics.

API Base URL

The HME CLOUD APIs can all be accessed by using the following base url:

https://api.hmecloud.com

Request limitations

Date range limitations

Data up to 90 days old is available to to be requested. Requests for older data will return the response error 422: "Invalid start date. Please ensure the date is within last 90 days only."

The most recent data available is 15 minutes or more behind the time the request is received. Requests for more current data will be empty.

Time difference between the requests StartDateTime and EndDateTime can be at most 72 hours. If a larger time window is requested the return response will be be error 400: "dates_is_out_of_range".

Number of request limitations

The API allows the same request, with all the same input parameters, to be sent 3 times within a 60 minute period. Any additional request with those parameters will return response error 429: "Attempts_limitation_exceeded".

Additionally, any requests coming in faster than 10 a second will also generate a 429 error response.

FAQ

  1. Can I include a timezone in the Start and End datetime parameters?

    • Yes, timezone can be included at the end.
    • Examples: 'Z' for UTC time; '-05:00' for EST; '-08:00' for PST. Daylight savings is not adjusted for in these times, and timezone value must be updated appropriately.

  2. Are the parameter names in the request case sensitive?

    • Yes. A request with parameter name of 'offset' will not be recognized while the parameter name 'Offset' will be recognized.

  3. What format should I use for the StoreNumberList?

    • An array of integers or an array of strings (with single or double quotes) is accepted. If a store number as it appears on the Cloud includes leading zeros (possible for Nitro timers only), then it must be a string and the leading zeros must be included.
    • Examples: [1001,245,9876]; ["1001","245","9876"]; ["1001","0245","9876"]

  4. Does it matter what order the parameters are included in the request?

    • No, the order does not matter.

  5. Data was requested and the returned response was 200:{"data": {"total": 0,...}. What does this mean?

    • It means that the Cloud data pool does not contain data that meet the requested parameters.
    • Reasons there may not be any data available:
      • Requested parameters are not correct
      • The timer is offline and has not uploaded data for the requested period
      • The timer did not record any valid Departure events during the requested period. This could be because there was no traffic through the drive-thru during that period, or all of the events could be exceptions (Pullins, Pullouts, Discards, etc). In this case, the Cloud Portal should be used to Remote Connect to the timer for verification.

  6. Once I have retrieved data for a time range, will it ever be updated/added?

    • No, data is sent from the timer in a first-in-first-out fashion. If a store record with departure time A has been retrieved, no records for that store prior to time A will be added or modified.
    • However, if you request time range [A-C] and the DepartureTime of the last returned record was B, where A < B < C, then there could still be records added later in the range [B-C].

  7. I received a response 429:"attempts_limitation_exceeded". What does that mean?

    • The Attempts_limitation_exceeded response comes back when you make the same request more than 3 times in 60 minutes. To avoid this, we recommend making changes to the requested Start or End times, or the Limit or Offset parameter. For initial development work and testing, it is recommended to set the Limit parameter to a lower number between 10 to 50. This limits the number of records returned in a single response to avoid dealing with large datasets when simply testing the processing. This can also be changed by 1 with each request to avoid the Attempts_limitation_exceeded error.
    • This response can also indicate that more than 10 requests per second have been made with the same auth-key no matter the parameters.

  8. When I make a request, how long may it take to return?

    • The DXS API will time out after 230 seconds.
