BK1_L_AttributionContact Returns NULL, but should be populated.

I was asked by our MLS to reach out in regards to this issue.

When making the following request the value of BK1_L_AttributionContact is always null:$filter=ListingId eq '391819' or ListingId eq '388010' or ListingId eq '391548' or ListingId eq '391819' or ListingId eq '392257' or ListingId eq '392427' or ListingId eq '392686' or ListingId eq '393096' or ListingId eq '396663' or ListingId eq '396657' or ListingId eq '396643'&$select=BK1_L_AttributionContact

Our MLS has told us that these fields (specifically for these listings) should contain data however.

Is there something I am doing that is causing these to always return null?

We're using the RESO API for the RAMaui MLS

Still working on this issue.

Are you getting any data returned in the AttributionContact field yet?

I re-ran the same query and BK1_L_AttributionContact still returns null in every case.

When you run the API call do you see results other than null?

Do you have another 'ListingID' that returns something other than null?

I'm aware that null is a valid response for this field, however those 'ListingIDs' listed in the API call above, as I'm told by our MLS, should have non-null data.

Scratch that, one of the ID's (396657) is in fact returning a value! Let me check with our MLS admin to confirm those other listings should have data as well. Maybe they sent the wrong list. Will follow up when I hear back.

It looks like 33 listings are now non-null. This is far fewer than I anticipated, however I suppose it is possibly correct.

Here is the API call I used to confirm: ne null&$select=ListingId, BK1_L_AttributionContact

Thank you for your help!
