password Yes Your Lemlist API key.

Getting your credentials

  1. Sign in to your Lemlist account.
  2. Open the settings area covering integrations or API access and generate an API key.
  3. Copy the key and paste it into the credential’s API Key field in BusyBot.

Permissions and scopes

The key acts on the Lemlist team account that issued it. Campaigns belonging to another team are not reachable with it.

Troubleshooting

  • 401 Unauthorized — the key is wrong or was regenerated in Lemlist.
  • Campaign not found — the campaign ID belongs to a different team than the key does.
  • Lead already exists — Lemlist deduplicates by email within a campaign; treat that as an expected outcome rather than a failure.

Frequently asked questions

Where is the key generated?

In the settings area of your Lemlist account covering integrations or API access.

Does it work across teams?

No — the key is scoped to the team that issued it, so campaigns in another team need that team's own key.

Does one key cover the node and the trigger?

Yes, both declare the same credential type.
