Overview
IDX Broker is an IDX platform built for real estate websites — it handles MLS listing display, property search widgets, and lead capture forms but stops short of CRM functionality. HighLevel is an all-in-one CRM that adds pipeline management, SMS/email automation, appointment scheduling, and custom objects for real estate-specific data like listings and property details. The migration from IDX Broker to HighLevel is fundamentally a data consolidation move: IDX Broker stores contacts (leads from property searches), saved searches, and custom lead form data; HighLevel receives these as Contacts with tags, custom fields, and a Property custom object. FlitStack AI accesses IDX Broker via its REST API using read-only credentials, extracts contacts with their property interest history and saved search criteria, and loads them into HighLevel's Contacts object. Saved search parameters map to HighLevel tags and custom text fields. Any IDX Broker lead forms become custom fields on the HighLevel Contact record. The migration does not include IDX Broker's website widget configuration, MLS data feed setup, or wrapper-page HTML — those are destination-side rebuilds that HighLevel's native features or third-party IDX integrations cover. Workflows, sequences, and automation logic built inside IDX Broker do not migrate; they require manual reconstruction in HighLevel's Workflow Builder. A delta-pickup window captures any new leads generated during the cutover.

Object mapping
Each row shows how a IDX Broker object lands in HighLevel, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
IDX Broker
Contact / Lead
HighLevel
Contact
1:1IDX Broker contact records map directly to HighLevel Contacts using a one-to-one field mapping. Name, email, phone, address, city, state, zip code, and lead source fields transfer as standard Contact fields in HighLevel. Any additional standard fields present in IDX Broker are reviewed and mapped accordingly. Original create and update timestamps are preserved as custom date fields (dateCreated__c, dateUpdated__c) for reporting continuity and historical accuracy.
IDX Broker
Lead Source / Origin
HighLevel
Contact Tag
1:1IDX Broker records how each lead was sourced (e.g., 'Listing Detail View', 'Saved Search Alert', 'Contact Form'). This origin data maps to HighLevel tags on the Contact record — one tag per source event, allowing workflow triggers in HighLevel based on how the lead originally entered the system.
IDX Broker
Saved Search
HighLevel
Custom Field + Tag
1:1Each IDX Broker saved search contains property criteria (location, price range, bedrooms, property type). These criteria are serialized into a HighLevel custom text field (Saved_Search_Criteria__c) and tagged with 'Saved Search' for segmentation. The raw criteria string is preserved so your team can recreate the search in HighLevel or an integrated IDX tool.
IDX Broker
Featured Listing / Property Interest
HighLevel
Property Custom Object
1:1IDX Broker tracks which listings a contact saved or favorited. This translates to a HighLevel Property custom object linked to the Contact via a many-to-one relationship. Property fields (address, price, MLS number, status) map to custom fields on the Property object. This object must be created in HighLevel before migration runs.
IDX Broker
Lead Form Submission
HighLevel
Custom Fields on Contact
1:1Custom fields collected via IDX Broker lead forms (e.g., 'Moving Timeline', 'Pre-Approved Status', 'Budget Range') map to identically named custom fields on the HighLevel Contact. Pick-list values in IDX Broker map to HighLevel drop-down custom fields with value-by-value mapping to preserve the same selectable options. Any required field settings or conditional visibility rules are documented during the audit phase for manual reconfiguration in HighLevel's form builder.
IDX Broker
Contact Owner / Agent Assignment
HighLevel
Contact Assigned User
1:1IDX Broker assigns leads to agent users by email address. FlitStack resolves each owner email against HighLevel user accounts by email match. Unmatched owners are flagged before migration — your team either creates the HighLevel user first or reassigns those contacts to a fallback user before the final run.
IDX Broker
Contact Notes / Internal Comments
HighLevel
Contact Notes
1:1IDX Broker stores notes per contact as text entries with timestamps and owner attribution. These transfer to HighLevel's built-in Notes feature on the Contact record, preserving the original note text, create date, and assigned user so nothing is lost in the transition.
IDX Broker
Website Account (My Listings Manager)
HighLevel
Contact Tag + Custom Field
1:1IDX Broker's My Listings Manager creates website accounts for buyers with saved properties and search alerts. The account status and saved listing count migrate as a 'My Listings Manager User' tag plus a Saved_Listings_Count__c custom number field, signaling engagement level in HighLevel without the portal functionality.
IDX Broker
Listing Data / MLS Feed
HighLevel
No Equivalent
1:1IDX Broker's live MLS listing data is sourced from a data feed and displayed via widgets. HighLevel has no native IDX or MLS integration — this data lives on your website, not in the CRM. The listing feed and widget configuration must be rebuilt using a separate IDX integration. Property interest data (which contacts viewed which listings) does migrate as described above.
IDX Broker
Workflows / Automations
HighLevel
Workflows
1:1IDX Broker's automation capabilities are limited to lead notifications and email alerts. HighLevel's Workflow Builder is a fundamentally different automation engine. All automation logic must be manually rebuilt in HighLevel. FlitStack can export a list of IDX Broker notification rules as a rebuild reference for your HighLevel admin.

Migration approach
Audit IDX Broker contacts and define the Property custom object schema
Before migration, FlitStack pulls a full export of IDX Broker contacts including all standard fields, custom form fields, saved search data, and listing interest history. We review the field inventory and identify any IDX Broker custom form fields that need HighLevel custom fields created in advance. Simultaneously, we define the Property custom object schema in HighLevel (address, price, MLS number, status, property type) based on the listing interest data in IDX Broker. A schema setup plan is delivered to your HighLevel admin before the migration run.
Resolve agent owners and create HighLevel custom fields
FlitStack matches each IDX Broker agent email against HighLevel user accounts. Any unmatched agents are flagged with a detailed list so your team can create the HighLevel users first. We simultaneously create all required custom fields on the HighLevel Contact object (Saved_Search_Criteria__c, Budget_Range__c, Moving_Timeline__c, Pre_Approval_Status__c, Source_System_ID__c) and set up the Property custom object with its fields and relationship to Contact.
Map lead sources and saved search data to tags and custom fields
IDX Broker lead origin data (Listing Detail View, Saved Search Alert, Contact Form) is mapped to HighLevel tags using a defined tag-naming convention. Saved search criteria are serialized and written to the Saved_Search_Criteria__c custom field. Saved listings per contact are counted and written to Saved_Listings_Count__c. Property interests are linked to the new Property custom object records. All mappings are documented in a field-level mapping sheet for your review.
Run sample migration with field-level diff
A representative sample of 100–500 contacts migrates first, including contacts with saved searches, property interests, and custom form data spanning various scenarios. FlitStack generates a field-level diff comparing each source IDX Broker record against the corresponding destination HighLevel record, so your team can verify tag assignment, custom field population, and Property object linkage before the full run commits. Any mapping discrepancies surface in the diff report for immediate correction. Once the sample pass receives approval, FlitStack proceeds with the complete migration run.
Execute full migration with delta-pickup window
The full contact migration runs against HighLevel. A delta-pickup window of 24–48 hours captures any new contacts or updated records created in IDX Broker during the cutover period. All operations are logged in an audit trail. One-click rollback is available if reconciliation against the IDX Broker source count reveals discrepancies. Post-migration, your team receives the export of IDX Broker notification rules as a reference for rebuilding automations in HighLevel's Workflow Builder.
