# Industry Taxonomy Update for Prospecting API

In November 2025, Lusha updated the Industry filter taxonomy to provide clearer, more standardized industry classifications. This update affects industry codes used in [Prospecting API](https://docs.lusha.com/apis/openapi/prospecting) calls and saved filters.

As part of this update:

- Some industries were renamed for better clarity
- New industries were added to cover emerging sectors
- Outdated industries were removed


## Who is affected

This taxonomy update is relevant if you:

- Use industry filters in your [Prospecting API](https://docs.lusha.com/apis/openapi/prospecting) search requests
- Have saved filters that include industry parameters
- Integrate industry data into your CRM or internal systems
- Build prospecting tables based on specific industry segments


## How to update

To ensure your API integration continues working correctly with the new taxonomy:

1. **Review your current API calls**
  - Check if you're using industry filters in your Prospecting API search requests
  - Identify which industry codes you're currently using
2. **Compare with the new taxonomy**
  - Download the [complete table of new industry codes](https://www.lusha.com/wp-content/uploads/2025/10/New-Industries-Taxonomy-Prospecting-API.pdf)
  - Verify whether your industry codes have been changed, removed, or added
3. **Update your API requests**
  - Replace old industry codes with the new codes in your API calls
  - Update any saved filters that use industry parameters
  - Test your updated requests to ensure they return expected results
4. **Update your documentation**
  - Document the new industry codes your team is using
  - Update any internal mapping or reference tables


## FAQs

**What happens if I don't update my industry codes?**

Your API queries may return inconsistent or incomplete results. Old industry codes may not match contacts correctly, leading to gaps in your prospecting tables.

**Will my existing saved filters still work?**

Saved filters using old industry codes may return different results after the update. We recommend reviewing and updating all saved filters that use industry parameters.

**How do I find out which industry codes changed?**

Download the complete table of new industry codes and compare it with your current codes. Industries that were renamed, added, or removed are indicated in the documentation.

**Can I still use the old industry codes?**

No, old industry codes that were removed or renamed will no longer return accurate results. You must update to the new codes.

**Will this affect my historical data?**

Historical data in your system will remain unchanged. However, new API calls will use the updated taxonomy, so you may need to update your internal mapping to maintain consistency.

**How long will it take to update my integration?**

The time required depends on how extensively you use industry filters. For most users, updating API calls takes 15–30 minutes.

**Is there a deprecation period for old codes?**

No, the change took effect on November 26th. We recommend updating your codes as soon as possible to avoid disruptions.
