Connect your Lusha API key to lemlist

Paste your Lusha API key in lemlist from the Integrations Marketplace if you’re using the manual Lusha connection flow.

If you need to connect Lusha to lemlist with your own API key, this article walks you through the exact setup flow shown in the product. You’ll open your settings, start the Lusha connection from Integrations, and paste your key into lemlist. This article covers the manual API-key setup only.

Limitations

  • This article applies only to the Lusha flow that asks for a Lusha API key.

  • For paying users, Lusha phone and email enrichment is built into the lemlist enrichment waterfall, with no Lusha API key, no Lusha account, and no extra credit charge. You accept Lusha's terms and conditions once, at your next enrichment. See Enrich leads with finder, verifier, and phone.

Prerequisites

  • You need access to Settings in your lemlist workspace.

  • You need a valid Lusha API key from your Lusha account.

Troubleshooting & pitfalls

Issue: You expected automatic activation, but you see Connect your Lusha API key

Root cause: You opened the manual Lusha API-key flow in Integrations.

  • For paying users, Lusha is already built into the enrichment waterfall, so you don't need to connect an API key. Accept Lusha's terms and conditions at your next enrichment.

  • Continue with the steps in this article only if you want to connect your own Lusha account.

Issue: You clicked Connect, but you do not have a key to paste

Root cause: You have not copied your API key from your Lusha account yet.

  • In the setup window, click Open Lusha settings.

  • Copy your API key from Lusha.

  • Return to lemlist and paste it into Lusha API key.

Issue: The Add API key to lemlist button is unavailable

Root cause: The Lusha API key field is still empty or incomplete.

  • Paste the full key into the Lusha API key field.

  • Check that nothing is missing from the beginning or end of the key.

  • Try again once the field is fully populated.

Issue: You can open Integrations but do not see Lusha

Root cause: Your workspace may not have access to the manual API-key flow.

  • For paying users, Lusha is built into the enrichment waterfall and needs no connection in Integrations.
