Ensure you have access to your Lob dashboard. 2. Ensure that you have your Lob API key. Your Lob API key can be found under the settings section under your name in the Lob dashboard. ## Step 1: Select Lob endpoint The HTTP URL to request in the connector is different for each action you can make to Lob. In the following example, we use the postcards API endpoint `https://api.lob.com/v1/postcards`. Visit the [complete endpoint list](https://lob.com/docs#intro) to select the endpoint appropriate for your use case.
