What are integrations?

Integrations connect your Base44 app to external tools and services without writing backend code. They are ideal whenever you want your app to go beyond the basics, such as automating tasks, launching your first MVP, keeping your team in sync, or connecting with the tools you already use.
You need a Builder Plan or higher to use integrations.

Example use cases of integrations

  • Sending welcome emails to new users of your app
  • Syncing your existing CRM with your app database
  • Alerting your team when someone submits a form
  • Generating content with AI tools
  • Pulling or updating data from external sources

Choosing an integration

You can add integrations in 2 ways: from the Integrations Catalog before you start building, or directly in the chat while you are building your app.

New apps

If you are building a new app, select an integration from our catalog before you write your first prompt. The integration will be built into your app from the start. You can browse the Integration Catalog for public (everyone), private (just you), or workspace (your team) integrations.
You must be logged in to access the integrations catalog.

To add a catalog integration for a new app:
  1. Log into Base44.
  2. Go to the Integrations Catalog in your dashboard.
  3. Select the integration and review what it provides.
  4. Generate an API key from the service’s Developer / API page and paste it into Base44 when prompted.
  5. Enter your first prompt to start building with that integration enabled.

  • If a service you need isn’t in the catalog, you can still connect it using our External API feature using backend functions. This lets you connect your app to any third-party service that provides an API, even if it’s not officially supported in our catalog.

Apps you have already built

You can add any integration at any time while building your app. Just describe what you want in the AI chat. It doesn’t have to be in the catalog.
Before you add your integrations, you need to enable backend functions in your app’s dashboard.

Examples of prompts for the AI chat to set up an integration

Add an OpenAI integration that summarizes new inputs
Connect to Resend to send a welcome email when a user signs up
Pull in company data from Airtable
When you request an integration in the AI chat, Base44 guides you step by step, asks you for the required API key, and automatically connects both the backend and frontend logic, so you can get up and running fast.

Getting your API keys

Most integrations require an API key, which acts like a private password between your app and the external service. Your API key proves ownership and keeps your connection secure. Base44 stores your key safely as a Secret, so your app can use it without ever exposing it to anyone else.
Never share your API key publicly. Treat it like a password.
To get your API key:
  1. Log into the external service (e.g. OpenAI, Resend, Notion).
  2. Find the Developer, API, or Integrations section.
  3. Click Create API Key or Generate Token and copy it.
  4. Paste your API key in Base 44. The way you do this depends on how you are setting up your integration:
    • If using the AI chat: Enter your API key in the AI chat when prompted.

    • If setting up manually: Save it as a secret:
      a. Click Dashboard in your app’s editor.
      b. Click Secrets.
      c. Click Add Secret.

Testing your integration

Before publishing your app, run a quick test to make sure everything works as expected. To test your integration:
  1. Use sandbox or test mode (for example, Stripe test keys).
  2. Try real user flows and edge cases.
  3. Check that inputs and outputs match your expectations.
  4. Monitor integration credit usage.
  5. Preview your app to catch slow loading, failed API calls, or missing data.

FAQs

Click on a question below to learn more about using integrations.
If you run into issues, check the following:
  • Your API key is correct and saved in Secrets.
  • Backend Functions are enabled (for Instant integrations).
  • You have enough active credits in the external service.
  • You’re using live credentials, not test ones.
  • Your API request includes the correct endpoint, payload, and parameters.
  • You haven’t hit the service’s rate limits.
To check your balance:
  1. Click your profile icon at the top right of your workspace.
  2. Select Settings.
  3. Click Workspace to view used and remaining credits for the current billing cycle.
You can also view your remaining credits while working on an app by clicking the Base44 logo at the top-left. Learn more about credits in Base44.
There are 2 types of API keys you may need to regenerate or update:
  • Third-party service keys: Regenerate your key in that service’s developer portal (e.g. OpenAI, Resend, Notion), then update it in Dashboard → Secrets.
  • Your Base44 account API key:
    1. Click your profile icon at the top right of your workspace.
    2. Select Settings.
    3. Click Account.
    4. Click Regenerate next to API Key.
Once regenerated, your Base44 API key updates across all of your Base44 apps automatically. If you’ve added your Base44 key in another service, make sure to update it there as well.

The integrations remain in your app, but they won’t work until you upgrade again to a Builder Plan or higher.
Yes. You can create custom integrations, reuse them across multiple apps, and share them with teammates in your workspace.If you set your integration to Public and it’s approved, it will appear in the catalog for all users, and you’ll earn 250 credits. Learn more about creating integrations.
Yes, you can add as many integrations as your workflow requires, connecting to different external services for different parts of your app.
For security reasons, external services like Stripe, OpenAI, or Notion don’t let third parties (even Base44) access your credentials automatically. Instead, you need to:
  1. Log in to the service.
  2. Go to the API or developer section.
  3. Generate your key.
  4. Paste it into Base44 as a Secret.
Once added, your app can use that key behind the scenes safely and without code.
Why this matters: API keys are like passwords for services. Keeping them private and user-controlled keeps your data safe and ensures only you authorize access.
It’s not currently possible to grant full permissions to a repository. However, you can export your application as a ZIP file and then import it into your own repository if needed.
Yes, you can add PayPal checkout to your Base44 app in just a few steps. First, activate backend functions in your app settings. Then, ask the AI chat to add a PayPal integration and enter your PayPal Client ID and Client Secret from your PayPal Developer account. Once set up, your customers will be able to pay securely with PayPal right inside your app.
