Making API Calls in Workflows
Discover how to configure HTTP requests within your automation platform to interact with REST APIs, sending and receiving data.
Making API Calls in Workflows is a free No-Code Automation lesson on CoddyKit — lesson 2 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the No-Code Automation learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Intro to API Calls
Sometimes, your no-code platform's built-in integrations aren't enough. That's where direct API calls come in!
- An API Call is like sending a specific request to another application's server.
- It allows you to fetch data, create records, update information, or trigger actions in apps that don't have a pre-built connector.
- This opens up a world of possibilities for advanced automation.
Why Make Direct API Calls?
Why would you need to make a direct API call?
- Access Unique Features: Some app features might not be exposed through standard integrations.
- Connect Niche Apps: Integrate with less common or custom applications.
- Fine-grained Control: Have precise control over the data you send and receive.
- Workarounds: Bypass limitations of existing connectors.
HTTP Methods: GET & POST
When you make an API call, you're usually performing an HTTP Request. Two common types are:
- GET: Used to retrieve data from a server. Think of it like reading information. It doesn't change anything on the server.
- POST: Used to send data to a server to create a new resource or perform an action. Think of it like submitting a form.
Other methods exist (PUT, DELETE), but GET and POST are excellent starting points for no-code.
Anatomy of an API Call
Every API call has key components:
- URL (Endpoint): The web address that specifies where to send your request.
- Method: (e.g., GET, POST) What kind of action you want to perform.
- Headers: Extra information about the request, like authentication tokens or content type.
- Body (Payload): The actual data you're sending (mostly with POST, PUT).
No-Code HTTP Module
Most no-code automation platforms (like Zapier or Make) have a special module for making custom API calls.
- It's often called "Webhooks & HTTP," "HTTP Request," or similar.
- This module provides fields to configure the URL, method, headers, and body.
- You'll map data from previous steps into these fields to make dynamic requests.
Example: Simple GET Request
Let's see a simple GET request. This example fetches a specific "todo" item from a public test API. Notice how the data is requested without a body.
Try running this example in a terminal:
curl "https://jsonplaceholder.typicode.com/todos/1"Configuring GET in No-Code
In your no-code platform, setting up a GET request involves:
- Selecting the "HTTP Request" action.
- Choosing the GET method.
- Entering the URL (e.g.,
https://jsonplaceholder.typicode.com/todos/1). - Optionally adding Query Parameters (e.g.,
?userId=1) or Headers (e.g., for authentication).
The platform will then make the call and provide the response data for subsequent steps.
Example: Simple POST Request
Now, a POST request to create a new "todo" item. Notice we include a Body with the data we want to send, and a Content-Type header.
Try running this example in a terminal:
curl -X POST
-H "Content-Type: application/json"
-d '{"title": "Learn APIs", "completed": false, "userId": 1}'
"https://jsonplaceholder.typicode.com/todos"Configuring POST in No-Code
For a POST request in your automation platform:
- Select the "HTTP Request" action.
- Choose the POST method.
- Enter the URL (e.g.,
https://jsonplaceholder.typicode.com/todos). - Add Headers, especially
Content-Type: application/jsonif sending JSON. - Provide the Body data, often in JSON format, mapping dynamic values from previous steps.
Understanding API Responses
After an API call, the server sends back a response. This response typically includes:
- Status Code: A number indicating the request's success or failure (e.g.,
200 OK,201 Created,404 Not Found,500 Server Error). - Response Body: The data returned by the API, usually in JSON format.
- Response Headers: Additional information about the server's reply.
Your no-code platform will then let you use this response data in subsequent steps.
Check Your Understanding
You want to retrieve a list of active users from an API endpoint /users without changing any data on the server. Which HTTP method should you use?
Recap & Next Steps
Today, we explored how to make direct API calls within your no-code workflows!
- We learned about GET (fetching data) and POST (sending data) methods.
- You now understand the key components: URL, Method, Headers, and Body.
- Making direct API calls unlocks endless possibilities for integrating almost any service with your automations.
Next, we'll dive into parsing the data you get back from these API calls!
