    FAQ

    Frequently Asked Questions

    • How long does a custom integration take?

      Standard Provider integrations (known API with documentation) take 1-2 weeks. Custom XML/CSV parsers take 2-3 weeks. Multi-source aggregation takes 3+ weeks depending on the number of providers. We confirm the timeline after reviewing your data source documentation.

    • What information do I need to provide?

      At minimum: the name of your MLS provider, any API documentation or sample data files, and your API credentials or feed URL. The more documentation you can share upfront, the faster we can start. If you only have a feed URL with no docs, we can still reverse-engineer the format.

    • Do I own the custom addon after delivery?

      You receive a fully working addon installed on your website. If the provider is new to us, the integration may also become a standard addon available to other customers in the future. Your specific configuration, field mappings, and import settings remain private to your site.

    • Will the integration work with future FW Real Estate updates?

      Yes. Custom addons follow the same architecture as our standard MLS addons. They are built to survive product updates. If a major product update requires addon adjustments, we handle it within the monitoring period at no extra charge.

    • What happens after the integration is deployed?

      We monitor the integration for 2 months after deployment. If the feed breaks, data quality drops, or the provider changes their API during that period, we fix it at no charge. After the monitoring period, consider our MLS Maintenance Add-on for ongoing monitoring.

    What our clients say

    Client reviews

    Our clients trust us to deliver quality results. Here's what they have to say about working with us.
    • Custom XML feed parser for regional MLS
      Our regional MLS wasn't in the standard addon lineup. They built a custom parser for our provider's XML feed that imports 800+ listings daily. Runs reliably every morning. we haven't had a single failed import in 6 months of operation.

    • Dual MLS aggregation with dedup
      Needed to aggregate listings from two different MLS providers into one website. The multi-source integration handles deduplication automatically and keeps everything synchronized. Delivered on time despite the complexity. Our agents see all listings in one place now.

    • Proprietary CSV to FWRE import parser
      Custom CSV import from our proprietary listing management system. They built a parser that handles our specific data format and maps it to FWRE fields. Needed one field mapping revision, but the final integration runs automatically via cron without issues.

      Real Estate Developer
    • Custom API connector for 1,200 listings
      Our MLS provider uses a non-standard API that two other developers couldn't integrate with. The custom addon they built imports 1,200 listings daily and has become a core part of our business operations. Worth every penny of the investment.

    • International JSON property feed addon
      Needed integration with an international property feed using a non-standard JSON format. The team analyzed the API docs, built the connector, and had listings importing within two weeks. Professional communication at every milestone.

      Agency Owner
    • Custom MLS addon with zero failures
      The custom MLS addon they delivered is just as reliable as the standard ones. Import scheduling, photo downloads, and field mapping all work perfectly. Six months in and we've had zero import failures. Great ROI on the development cost.
