API Version 2.0
This page contains the information about how to use version 2.0 of the API.
Please see the RESO Enums To Lookups Transition doc for changes that went live March 8, 2022 at 8pm MT and completed by 10pm MT.
API Access
To get data, target the odata based Web API like so:
1
https://api.mlsgrid.com/v2/Property?$filter=OriginatingSystemName%20eq%20%27actris%27%20and%20ModificationTimestamp%20gt%202020-12-30T23:59:59.99Z&$expand=Media,Rooms,UnitTypes
Copied!
With the following header
Header
Value
Authorization
Bearer access_token
Explanation of the URI segments
The URL shown above has the following segments (with explanations)
Segment
Description
https://api.mlsgrid.com/v2/
The main location of the API Service for now and the future
Property
The resource name for the data that you want to download
$filter
Using an odata query. This is limited for replication purposes.
$expand
Contains the list of expanded resource types you want included in the returned data.
All data is compressed using gzip compression to shrink the overall payload size.
Limitations of Replication API
At this writing there are several limitations imposed on the Web API for the purpose of replication. These limitations are imposed to make the generally heavy odata faster for this specific use case.
Here are limitations imposed:
Limitation
Description
Each request must contain a single OriginatingSystemName specified in the filter criteria of the request.
There are only a few fields you can query the service with. This includes timestamp and status fields. See below for a list of all fields.
$expand calls
$expand is limited to specific resources and types due to the custom nature of our API service. Please see the Expanded Resources section of the docs for more information. We do not support $select or $orderby on the $expand resources.
NOTE: If you use expand in the request, the records per request limit reduces to 1000 at most per request. If you set $top=2000 or 5000 for example you will receive an error.
5000 records per request
You can receive at most 5000 records per request. If you set $top=6000, for example, you will receive an error. The application will default to 500 records per request if not specified.
or operator
The query must include no more than 5 'or' operators per query.
NOTE: It is preferred to use the in operator instead which is new in version 2.0.
Otherwise, users can select for specific fields as expected using the $select param in the URL.
Replication
Here are some examples of how you will use this API for replication. All examples assume the use of the headers being set properly for authentication purposes.
Initial Import
This is what the initial import request will look like:
1
https://api.mlsgrid.com/v2/Property?$filter=OriginatingSystemName%20eq%20%27actris%27%20and%20MlgCanView%20eq%20true
Copied!
The initial import would grab the first "page" of data. We don't want any deleted records so we set MlgCanView to being "equal" to true.
Next Link
To get the next page of data from the request, as part of the response body you will find a field called @odata.nextLink which contains a url. You can use this url as the next request to page through the data. You would continue to use the next link to get the next page of data until the response no longer contains a next link. Here is a snippet that shows what the next link looks like in the json.
1
"MlgCanView": true,
2
"ModificationTimestamp": "2019-02-01T00:55:41.516Z",
3
"OriginatingSystemName": "actris"

}

7
}
Copied!
Errors during import
If you encounter an error during your initial import you can avoid re-downloading any records that you already received and continue where you left off by adding the ModificationTimestamp that you last received to the initial import query:
1
https://api.mlsgrid.com/v2/Property?$filter=OriginatingSystemName%20eq%20%27actris%27%20and%20MlgCanView%20eq%20true%20and%20ModificationTimestamp%20gt%202020-12-12T00:00:00.000Z&$expand=Media,Rooms,UnitTypes
Copied!
We order our requests by ModificationTimestamp by default so that you do not miss changes that occur during your download and so that you can pick up where you left off in this manner.
After Initial Import
After you have the initial data fully downloaded, you would switch to using replication queries which do not contain an MlgCanView filter in them. This allows you to get all changes to the data including changes to MlgCanView=false so that you know when data is removed from the feed and needs to be deleted from your local data store. If you choose to store only a subset of the data in your local data store, your replication queries need to contain the greatest ModificationTimestamp you have received in the data from the api regardless of whether or not you choose to store the records you receive. This avoids repulling the same data over and over again.
Here is an example replication query:
1
https://api.mlsgrid.com/v2/Property?$filter=OriginatingSystemName%20eq%20%27actris%27%20and%20ModificationTimestamp%20gt%202019-02-04T23:59:59.99Z&$expand=Media,Rooms,UnitTypes
Copied!
This should be very familiar to anyone who has used RETS before and needed to replicate over that service.
Signal Fields
The following fields when they have changed indicate that action must be taken by the consumer with regard to their local data store.
Resource or Expanded Resource
Field
Action to Take
ALL
ModificationTimestamp
The record data has changed, replace the contents of your local copy of the record with the updated copy received during replication.
ALL
MlgCanView
When changed to false, the record is no longer valid for the feed type you consume and must be removed from your local data store.
Property, Member, Office
PhotosChangeTimestamp
This value will not change without also having the ModificationTimestamp change. If this timestamp changes, it means that the media records have changed. Replace the contents of your local copy of any media records with the updated copies received during replication. Pay attention to any MediaModificationTimestamp updates as noted below.
Media
MediaModificationTimestamp
This value exists on the Media subdocuments of a Property, Member, or Office record. None of these values will change without also having the ModificationTimestamp of the Property, Member, or Office record change. During regular replication, if the MediaModificationTimestamp of a media record is new or different from what you had before, the image file has changed and needs to be re-downloaded using the MediaURL of the media record.
Here is an example of a typical sequence of events for how to use these signal fields when receiving updates to records.
- 1.Query the API for updates using the greatest ModificationTimestamp from your local database for this resource.
- 2.While saving each record received, take the following steps:
- 3.Look to see if the MlgCanView field is false. If it is, delete or mark your local data copy to be deleted asynchronously from your data set.
- 4.Look to see if the PhotosChangeTimestamp has changed since the last time you received this record. If it has changed, then replace your local media records with the ones you've received in the update.
- 5.The key of the Media record is the MediaKey. Match up your records by the MediaKey. As you replace each media record by its MediaKey, look to see if the MediaModificationTimestamp has changed. If it has changed, re-download or mark to re-download asynchronously the image file using the MediaURL for this media record.
- 6.If the MediaKey no longer exists mark that record deleted or to delete asynchronously.
- 7.After taking all needed action, save off the ModificationTimestamp as the greatest ModificationTimestamp you have received back from the API for this resource and then repeat for the next record.

Resource Naming
The following is a list of the resource names (or entity sets) to use in the request URL.
Resource Endpoint
Expandable Resources
Description
Property
Media,
Rooms,
UnitTypes
Property Resource. This resource contains all listings for sale or lease.
Member
Media
Member Resource
Office
Media
Office Resource
OpenHouse

OpenHouse Resource
Lookup

Lookup Resource
Expanded Resources
The expanded resources are a sub document of the resource that they belong to. For example the Media records exist as an array of records called Media on the Property Record and are given through the api as part of the Property record. If the ModificationTimestamp of the Property record changes, the contents of the Media sub document should be replaced by whatever is returned in the updated record.
The following is a list of the expandable resources and their corresponding Resource Names that have the ability to expand them. This is basically the same list as above but inverted:
Expanded Resource Name
Resources that can expand this resource
Description
Media
Property,
Member,
Office
Media expandable resource. These are the media files associated with a Property, Member, or Office record.
Rooms
Property
Rooms expandable resource. These are the Room records associated with a Property record.
UnitTypes
Property
UnitTypes expandable resource. These are the UnitType records associated with a Property record.
Rooms and UnitTypes
RESO expects these expanded collections to be named differently on the records they are expanded onto. These collections are referenced in the nav links in the resource metadata. This is how the requests and data look:
Metadata
The field name of the data in the Property or other resource record will match the name in the nav link located in the resource it expands from. The Type of the nav link will indicate what EntityType that field name corresponds to so that you can find the definition for that expanded type in the metadata.
Example Metadata Nav Links:
1
<NavigationProperty Name="Rooms" Type="Collection(org.reso.metadata.PropertyRooms)"/>
2
<NavigationProperty Name="UnitTypes" Type="Collection(org.reso.metadata.PropertyUnitTypes)"/>

Deleted Records
MlgCanView - Deleted Listings, Off Market Listings, Etc
Each record in the system has a field called MlgCanView which is a boolean field and indicates whether the record should be kept in your database or not. This is how we have implemented our delete mechanism. When you receive an updated record during replication, you should first check this flag to see what action to take with your local copy of the record.
- IF true, then save or update the existing record in your db.
- IF false, then remove the record from your database (or never save it in the first place).
This value can be changed to false based on a number of different reasons.
The following are a few example reasons:
- The property was deleted.
- The property listing office decided that they don't want to feed out any of their listings.
- The property changed status and made it unavailable in IDX
- Etc.
The MlgCanView field is a specific field to the MLS Grid that tells you whether the record should be kept in your database. (note that any field with the prefix "Mlg" is specific to the Grid)
Deleted Expanded Resource Records
There is no delete flag for expanded resources as they exist as a part of the record they come with. As is the case with all other fields on the record, if you get records or values that are different than what you currently have, replace it with the new records and values you've received. If some of the data in your local data store no longer exists in the updated data that you received, remove it.
Media
The expanded media contains data describing photos associated with Properties, Members, and Offices.
The primary identifier of the media records is the MediaKey field. This is the field that uniquely identifies a record.
In order to retrieve the photo associated with the media record, you will need to use the url provided in the MediaURL field to download the image. The url is for the highest resolution photo that the MLS provides to us.The URLs contained in the Media resource are to be used ONLY for the purpose of downloading a local copy of the image file. DO NOT use these URLs on your website or in your application.
Lookups
This resource contains all of the lookup values for an mls. We recommend using the following queries to replicate and keep your Lookup data up to date:
Initial Data Import Request

https://api.mlsgrid.com/v2/Lookup?$filter=OriginatingSystemName eq ‘actris’ and MlgCanView eq true
Copied!
Regular Replication Requests
1
https://api.mlsgrid.com/v2/Lookup?$filter=OriginatingSystemName eq ‘actris’ and ModificationTimestamp gt [GREATEST ModificationTimestamp FROM YOUR DATABASE FOR THIS RESOURCE]
Copied!
Replicate from this resource the same way you would replicate from any of the resources using the Greatest ModificationTimestamp from the records you've received so far when querying for the latest changes.
Please do not pull from this resource more frequently than once a day as this resource will not likely change more than once a day. Pulling this resource with the same frequency as the rest of the resources may result in interruption of service for inefficient usage practices.
If you receive an update to MlgCanView: false on any of your lookup records, you should remove it from the list of possible values for that LookupName for the OriginatingSystemName on the record.
Example Lookup Record
The LookupKey is the primary identifier for this resource. Each record indicates that a lookup exists and is being used or not used by a particular mls depending on the value of the MlgCanView flag. The ModificationTimestamp will update whenever the Lookup record has changed.

Example Field Metadata with a Lookup:
Fields that have a lookup collection associated to it will appear like this in the metadata. In these 2 cases, the BodyType field uses a Lookup with the LookupName of BodyType in the Lookups collection. Possible values for this field can be found by looking in your local copy of the Lookups data for values assocated to the BodyType lookup. Same For StandardStatus. Lookup values for StandardStatus have a LookupName of StandardStatus in the lookups collection and you can search your local copy of the lookups collection for values associated with the StandardStatus Lookup.

Searchable Fields with Lookups
The PropertyType and StandardStatus fields are defined in the Lookups collection. You can search by the lookup value for these fields when performing a request.
Example Query by StandardStatus Request:
1
https://api-demo.mlsgrid.com/v2/Property?$filter=StandardStatus eq 'Active Under Contract' and OriginatingSystemName eq 'actris'
Copied!
StandardStatus
Querying by the StandardStatus field is a special case because it is enumerated. The following example shows the syntax needed.
To get all of the records that have an Active Under Contract StandardStatus, you must use the name of the status in order to query for it. (Note that in the table below the name is 'ActiveUnderContract' without spaces. These names are also contained in the StandardStatus enumeration metadata in the API but are provided here for convenience).
This is the syntax for a request for all records with an Active Under Contract StandardStatus value:
1
// Query by the name
2
https://api.mlsgrid.com/v2/Property?$filter=OriginatingSystemName%20eq%20%27actris%27%20and%20StandardStatus+eq+%27Active%20Under%20Contract%27

PropertyType
Querying by the PropertyType field is a special case because it is enumerated. The following example shows the syntax needed.
To get all of the records that have a PropertyType value of 'Commercial Sale', you must use the name of the PropertyType in order to query for it. (Note that in the table below the name is 'CommercialSale' without spaces. These names are also contained in the PropertyType enumeration metadata in the API but are provided here for convenience).
This is the syntax for a request for all records with a Commercial Sale PropertyType value:
1
// Query by the name
2
https://api.mlsgrid.com/v2/Property?$filter=OriginatingSystemName%20eq%20%27actris%27%20and%20PropertyType+eq+%27Commercial%20Sale%27

Prefixed KeyField Values
In order to maintain uniqueness across IDs, it is necessary to prefix our Key and MlsId fields throughout the data. Any field that is a Key or an MlsId field or is a reference to a Key or MlsId field in one of our other resources will be prefixed with an MLS specific prefix. This prefix should be removed from the data prior to displaying externally but must be added back whenever requesting records within the MLS Grid.
Here are a few examples:
If my ListingKey for a record in the MLS system was '123456' and my MLS's prefix was 'ACT', I would search in the MLS Grid for a record with a ListingKey equal to 'ACT123456'. If I wanted to display this record on my website, I would display '123456' as the key on my website.
If I have a problem with the OpenHouse records for one of my properties and I need to troubleshoot this specific record I might search for OpenHouse records by the MlsId of the property record. To find open house records for a property record, if the MlsId for the MLS's property record was '456789' and the MLS's prefix was 'ACT', I would search the OpenHouse resource for records where the ListingId is equal to 'ACT456789'.
Finally, if I wanted to find the Member record in the MLS Grid for an MLS's property record with a ListAgentMlsId of 'A10001', I would search the Member resource for the MemberMlsId equal to 'ACTA10001'. If I also search for the Property record from the MLS Grid, I can expect that the ListAgentMlsId in the data would be equal to 'ACTA10001' which would match the MemberMlsId of the Member resource record I received.
The following are the Key and MlsId prefixes for each MLS source:
