Last updated: July 16, 2026

This guide covers the Lusha Enrichment Integration in Nooks. It will walk through the steps to connect Lusha to Nooks, discuss how the enrichment feature works, and cover some of the frequently asked questions about the integration.

Background

Nooks Enrichment helps users quickly find new mobile numbers and email addresses for their prospects. This tool helps reps save time, increases coverage, and improves connect and email deliverability rates.

The Lusha integration enables reps to leverage Lusha for enriching prospect phone numbers and emails within Nooks. Reps can use Lusha either as a standalone provider or as part of a waterfall enrichment process, which sequentially searches multiple providers for new phone numbers.

Setup Requirements

The Nooks <> Lusha integration requires your team to have a Lusha Pro, Premium, or Scale plan. If your team is on a different Lusha plan, you will be unable to complete the integration setup steps. 

To complete the integration setup steps, you will need to be an admin or manager in Lusha, and an admin or manager in Nooks.

Integration Setup Steps

  6. Press the Connect Lusha button to connect the integration. 

Note: If you update, rotate, or revoke your Lusha API Key after connecting the Nooks <> Lusha Enrichment Integration, you will need to reconnect the integration with your updated Lusha API Key, as the old one will no longer function.

Once the Lusha integration is connected, users will be able to use Lusha to find new phone numbers in Nooks. If your team is using a custom Waterfall Enrichment or syncing Nooks Numbers results to fields in your CRM, you can now configure those settings for Lusha. 

Phone Number Enrichment with Lusha

When using Lusha for prospect phone number enrichment, Nooks prioritizes finding a new mobile number. 

If your team has configured successful enrichments to map to a field in your CRM, Nooks will map the new mobile found in Lusha to that field on the corresponding prospect’s record in your CRM. 

Email Enrichment with Lusha

When using Lusha as part of your team’s email enrichment waterfall, Nooks will look for any email address match for the prospect. If one is found, it will be returned and written back to the standard email field on the corresponding prospect’s record in your CRM.

Lusha Credit Usage

When Nooks enriches a number or email using Lusha, credits will be deducted from your organization’s credit balance in Lusha. Credits are not deducted from your Nooks Enrichment credit balance. 

Setting Per User Credit Limits

After connecting the Lusha enrichment integration, you can limit the number of Lusha credits each user can use via the enrichment integration. To do so:

  1. In Nooks, o to Settings → All Settings.

  2. Under Integrations, select Enrichment.

  3. In the Lusha enrichment card, click Set per-user limit.

    1. Toggle on Enable per-user cap.

    2. Enter the number of bulk credits users can use from Lusha on Nooks enrichments.

    3. Optionally, toggle on Refill Monthly for users' credit limit to be reset to your Workspace's configured limit at the beginning of each month.

The limit is a blanket user that applies equally to all users. Nooks does not support setting different limits for different users.

What Happens when the Per-User Credit Limit Is Reached

When a user reaches the per-user credit limit, they can no longer use Lusha for new enrichments in Nooks until the per-user credit limit is raised by an admin/manager, or their credit limit resets at the beginning of the month (if the monthly refill option is enabled).

Users who hit their limit receive an error message along the lines of:

Provider Limit Reached

Lusha has 1 enrichment remaining for this rep, but this enrichment would use 2 enrichments.

Select fewer prospects or ask a manager to raise this provider limit in Phone Data settings.

Users can unblock themselves from this error by:

  • Selecting fewer prospects to enrich with Lusha (if there are sufficient credits to enrich some prospects in the batch).

  • Choosing a different data provider to enrich with.

  • Asking a Workspace admin or manager to increase the per-user credit limit.
