HOW TO: Receive notifications of feed changes

In addition to the retrieval of records and objects, RETS servers provide an extensive section of metadata descriptions that can help describe the types of information you’re allowed to retrieve including data categories, field descriptions, field types, field lengths, lists of values allowed in particular fields, etc. This metadata is generated and delivered by the RETS server and provides you with a view of how various aspect of an MLS’s data structures are configured.

From time to time, an MLS may choose to make changes to their data formats in order to better serve the needs of their members. For example, an MLS may choose to add new fields that provide more details about a particular listing. When changes like this are made, the RETS metadata is automatically adjusted as necessary.

MLS’s using flexmls Web have access to extensive controls that can impact how data is represented and delivered. When an MLS is aware of how a change will impact third parties pulling data through RETS, they’ll often send announcements ahead of time introducing the change so all data recipients can prepare. However, it’s often the case that the overall impact of a particular change isn’t completely known.

Because some metadata changes can be disruptive to outside users pulling and processing this data, FBS now has a process in place to email all RETS users in advance when one of the following change conditions is anticipated:


All RETS users will be added to this distribution list upon signing up for RETS credentials with an MLS. There is no need to request special access to receive these notices. If you wish to opt out of all notifications moving forward please use the opt out feature built into the notification email.
