Edmonton RETS Feed - Intermittent Download Issues

  • retag add tags

Hi Everyone! We are having intermittent issues with our RETS connection and I am hoping you can take a look. Every few RETS requests that we send, we get the following reply from the server:

RETS ReplyCode="20037" ReplyText="RETS-UA-Authorization failed." /

It happens sporadically, but enough to disrupt our data downloads. We checked with the MLS and they could find nothing wrong with the account. The issue persists, however, it's not a matter of whether the credentials work or not, it's a matter of the credentials failing half the time we use them.

If we were to run, for instance, 50 basic Metadata or GetObject RETS in a row using our credentials, 50% of our requests (based on recent observation) fail with the RETS ReplyCode="20037" ReplyText="RETS-UA-Authorization failed." / Another test is running a GetObject request 50 times where "Type=Photo&Resource=Property&id=66977937"

Can you please investigate as this is causing havoc with our downloads UN: cwolfnet

The only failure I see in our logs for your account is this search. It failed because of the space after L_Last_Photo_updt. If I remove the space it works fine.

QueryType=DMQL2 &Format=COMPACT-DECODED &Select=L_DisplayId,L_Last_Photo_updt,L_PictureCount &Count=1 &SearchType=Property &Query=(((L_Status=|1_0,2_0,3_0),(L_Last_Photo_updt =2018-05-04T12:28:39+))),((L_Status=|1_0,3_0),(L_IdxInclude=0,2)) &Class=RE_1 &Limit=1500

Since you are connecting through RETSIQ contact product, you will need to contact the MLS to see if there are issues within that application.

Is it possible to runt the query as requested? How about a simple request like this one: 'SearchType=Property&Class=RE_1&QueryType=DMQL2&Count=1&Format=COMPACT-DECODED&StandardNames=0&Query=(L_Status=|1_0,2_0,3_0)&Select=L_DisplayId&OFFSET=9001' Run this 50 times in a row, and let me know how many times you get this:


<rets-status replycode="0" replytext="Operation Successful"/> vs failure

I don't have access to RETSIQ. They are a middle layer between the Vendor's RETS client and Paragon RETS server. The actual MLS handles configuration and access.

Were you able to get your issues fixed through the MLS?

I emailed Marko Martinovic and Mathew Kallumadil at the MLS yesterday morning and have not received a reply as of yet.

Have you made any progress with this yet?

We never received a response from the MLS so we ended up having to do a number of workarounds in the code in order to make sure we were getting the data we need.
