How to connect lemcal with any tool via API

By the end of this tutorial, you'll know how to generate a new lemcal API key from Settings → Integrations and where to find other available integrations like Calendly, Zoom, Stripe, Zapier, and Webhooks.

Why this matters

Your API key is what lets external tools securely connect to your lemcal account. Knowing where to generate and manage it helps you move faster when setting up custom workflows, automations, or third-party integrations.

Prerequisites

You should already know how to log in to your lemcal account and access your workspace.

Core lesson — Generate your API key

The lemcal API offers a comprehensive set of endpoints that allow developers and users alike to interact with lemcal's services programmatically. From managing events and calendars to retrieving user information, the API facilitates a broad spectrum of operations, making it an invaluable resource for customizing and extending the functionality of lemcal. Detailed documentation, including available endpoints, request formats, and response data, can be found at lemcal's Developer Documentation. 📆

Phase 1: Open your settings

Open your account menu and go to Settings. From your lemcal workspace, click your profile in the bottom-left corner, then select Settings. This takes you to the area where account-level and team-level configuration options are managed.

‍

Phase 2: Go to Integrations and generate your key

Open the Integrations page and generate a new API key. In Settings, click Integrations, then scroll to the API section and click Generate new key. This is where lemcal now centralizes API key generation, alongside other available integrations such as Calendly, Zoom, Stripe, Zapier, and Webhooks.

Once generated, your new API key will be displayed. It's important to copy and securely store this key, as it may not be shown again. Treat your API key as sensitive information, similar to a password.

With your API key in hand, you're ready to connect lemcal with other tools and platforms. When setting up the integration on the external tool's side, you'll typically be asked to provide the API key. This creates a secure connection between lemcal and the tool so data can be exchanged automatically.

Practical application

A common use case is connecting lemcal to an internal tool, automation platform, or custom workflow that needs to read meeting data or trigger actions based on scheduling activity. In the same Integrations area, you can also review other connection options available in your workspace, including Calendly, Zoom, Stripe, Zapier, and Webhooks.

Troubleshooting & pitfalls

Issue: You can't find where to generate an API key.

• Root cause: The API key is no longer generated from the older location.
• Fix: Go to Settings → Integrations and use the Generate new key button in the API section.

Issue: Your integration is not authenticating.

• Root cause: The API key may have been copied incorrectly or an old key is being used.
• Fix: Generate a new key, copy it carefully, and paste it directly into the external tool without extra spaces.

Issue: You're not sure whether you need the API section or another integration.

• Root cause: The Integrations page includes both direct integrations and developer access options.
• Fix: Use the API section for custom or developer-based connections, and use integrations like Calendly, Zoom, Stripe, Zapier, or Webhooks when your workflow matches one of those tools.
