Lemlist

Prerequisites​

Before creating a Lemlist credential, you need to obtain a personal API key from your Lemlist account. The API key is required to authenticate with the Lemlist API using Basic Authentication.

To obtain your API key, follow these steps:

  1. Sign in to your Lemlist account using your credentials.

  2. Navigate to Settings > Integrations in your Lemlist account, or access your account settings from the account menu.

  3. In the Integrations or API settings section, locate the API Keys or API Settings section where you can view and manage your API keys.

  4. If you don't have an existing API key, click Generate API Key or Create API Key to create a new API key. You may be asked to provide a name or description for the key to help identify it later (e.g., "Nexla Integration").

  5. After generating the API key, copy it immediately. The API key is typically displayed only once for security reasons and may not be accessible again after you navigate away from the page.

  6. Store the API key securely, as you will need it to configure your Nexla credential. The API key provides full access to your Lemlist account data, so treat it as sensitive information.

The API key is used as the password in Basic Authentication, with an empty username. The credentials are sent in the Authorization header using Basic Authentication for all API requests to the Lemlist API. The Lemlist API provides access to various resources including campaigns, activities, unsubscribes, hooks, and leads. For detailed information about API key setup, authentication, and available API endpoints, refer to the Lemlist API documentation and Lemlist API authentication documentation.

Credential Name & Description​

  1. Enter a name for the credential in the Credential Name field and a short, meaningful description in the Credential Description field.

    Resource descriptions are recommended but are not required. They should be used provide information about the resource purpose, data freshness, etc. that can help the owner and other users efficiently understand and utilize the resource.

Basic Authentication​

Lemlist uses Basic Authentication for all API requests. The API key is used as the password in Basic Authentication, with an empty username. This authentication method is specific to Lemlist's API and is used to authenticate all API requests.

  1. Enter your Lemlist API key in the API Key field. This is the personal API key you obtained from your Lemlist account settings. The API key is used as the password in Basic Authentication, with an empty username. The API key is sent in the Authorization header using Basic Authentication for all API requests to the Lemlist API. The API key is sensitive information and must be kept confidential.

    Keep your API key secure and do not share it publicly. The API key provides access to your Lemlist account data and should be treated as sensitive information. Your Lemlist API key can be found in your Lemlist account settings (API Keys or API Settings section) where you manage API keys. The API key is used as the password in Basic Authentication, with an empty username. This authentication format is specific to Lemlist's API and must be used exactly as specified. If your API key is compromised, you should immediately regenerate it in your Lemlist account settings. For detailed information about obtaining and managing API keys, API authentication, and available endpoints, see the Lemlist API documentation and Lemlist API authentication documentation.

Save the Credential​

  1. Once all of the relevant steps in the above sections have been completed, click the Save button at the bottom of the overlay to save the configured credential.

  2. The newly added credential will now appear in a tile on the Authenticate screen during data source/destination creation and can be selected for use with a new data source or destination.
