Making Your First Request

A step by step guide to making your first request with the Layer API

If you're new to working with APIs or just want a step-by-step orientation on how to make an API request with Layer, you're in the right place.

In this step-by-step guide, we'll walk you through the process of making a request to fetch all Categories associated with a specific Layer Project.

Prerequisites

1. API Token: Ensure you have a valid bearer token for authentication. You can find your token in your Layer user dashboard here.
2. Project ID: You'll need the ID of the project for which you want to retrieve categories. You can find your project ID by opening your layer project in a web browser and copying the project ID from the url. Our Introduction page includes a guide for finding your Project ID.

Step-by-Step Guide

Step 1: Set Up Your Environment

Before making the request, ensure you have a tool or environment ready to send HTTP requests. Some popular options include:

• Postman: A user-friendly tool for API testing. Layer has published a Postman Collection to make getting started with the Layer API easy
• cURL: A command-line tool for sending HTTP requests.

For this guide, we'll use cURL, but the process is similar for other tools.

Step 2: Construct the URL

The base URL for the endpoint is:

https://api.layer.team/projects/{PROJECT_ID}/categories

Replace {PROJECT_ID} with the actual ID of your project. For example, if your project ID is 23rv09jbrgb0sdkan, the URL becomes:

https://api.layer.team/projects/23rv09jbrgb0sdkan/categories

Step 3: Make the Request

Using cURL, construct, and execute the following command:

Bash

curl -X GET "https://api.layer.team/projects/23rv09jbrgb0sdkan/categories" \
-H "Authorization: Bearer {YOUR_API_TOKEN}"

Replace {YOUR_API_TOKEN} with your bearer token.

Step 4: Review the Response

Upon executing the command, you should receive a JSON response containing a list of categories for the specified project. The response will look something like this:

JSON

{
  "categories": [
    {
      "createdAt": "2023-08-01T12:00:00Z",
      "count": 5,
      "initials": "IS",
      "instance": "Issue",
      "modelCategory": true,
      "order": 1,
      "name": "Punch List",
      "id": "2e03d9ev0erjkfg",
      "updatedAt": "2023-08-02T12:00:00Z"
    },
    ...
  ]
}

Each category in the list will have properties such as createdAt, count, initials, instance, modelCategory, order, name, id, and updatedAt.

Step 5: Handle Errors

If there's an issue with your request, you might receive an error response.

Common issues include:

• Invalid bearer token. You can try clicking Regenerate Token in the Layer dashboard to create a new one. Review the Authentication Guide for more details
• The project doesn't exist or is inaccessible

Conclusion

Congratulations! You've successfully made your first request to retrieve categories from a project using our API. As you become more familiar with the platform, you can explore other endpoints and functionalities to make the most out of your projects and data.
