Let's Calendar API Documentation

This is the complete API documentation for connecting to the Let's Calendar API using MindCloud's Universal API. If you are new to MindCloud, start with the Introduction to see how one API can sit in front of many different apps.

MindCloud is an integration company that offers one normalized API to access 3,100+ apps from a single place. It cleans up provider-specific quirks, keeps requests and responses consistent, and centralizes authentication so you do not need to manage separate flows for every app. Browse other apps.

Meet Let's Calendar: Create, send, and track calendar invite campaigns. Keep reading to get started.

Quickstart

Before you run your first Let's Calendar request, you need three things:

  1. A MindCloud account — sign in or create an account at MindCloud.
  2. A MindCloud API Key — create one in API Keys. Keep it on your server.
  3. At least one Let's Calendar connection — create or choose one in Connections. Note its connectionId.

Every Let's Calendar action uses the same URL pattern:

https://connect.mindcloud.co/v1/universal/letsCalendar/latest/actions/{actionSlug}

You need a MindCloud API Key and a Let's Calendar connection. Then call an action such as Export Campaign Contacts:

curl --request GET \
  --url "https://connect.mindcloud.co/v1/universal/letsCalendar/latest/actions/export-campaign-contacts" \
  --header "Authorization: Bearer $MINDCLOUD_API_KEY" \
  --get \
  --data-urlencode "connectionId=$CONNECTION_ID"

Every response comes back in the same envelope, with your rows in a data array:

{
  "success": true,
  "data": [
    { "id": "1042", "name": "Ava" }
  ],
  "meta": {}
}

After your first request works, use Shape your requests to control arguments, pagination, filtering, fields, and errors.

Authentication

Authentication has two layers. Your MindCloud API Key authenticates the request to MindCloud, sent as a Bearer token in the Authorization header. The connectionId selects the connected Let's Calendar account that should run the action. MindCloud stores and refreshes the Let's Calendar credentials behind that connection, so you never send provider tokens with your requests.

Pass connectionId in the query string for GET and DELETE actions, and in the JSON body for POST, PUT, and PATCH actions. Keep your MindCloud API Key on your server; do not ship it in browser code, mobile apps, public repositories, or logs.

Connect Let's Calendar

You need a Let's Calendar account plus an API client key and secret key from your dashboard.

  1. Sign in to the Let's Calendar dashboard

    Open the Let's Calendar panel and sign in to the account that owns the API key you want to use.

  2. Open your API key settings

    In the dashboard, find the API key settings for your account and create a new API key or regenerate the existing one if you do not have both values yet.

  3. Copy the client key and secret key

    Copy the API client key and the API secret key exactly as shown.

  4. Paste the credentials into this connection

    Paste the client key into Client Key and the secret key into Secret Key, then save the connection.

  5. Finish the connection

    Save the connection so MindCloud can exchange these credentials for a bearer access token when the app runs.
