How to Use Pulse Public APIs

This page describes how to use the Pulse Public APIs to authenticate, obtain a JWT token, and access the GraphQL Playground for running API queries.

Obtain a JWT Token

To access the Pulse APIs, first obtain a JSON Web Token (JWT).

1. Open your terminal or command prompt.
2. Run the following command to log in and retrieve the JWT token and user role:

curl -i 'http://<pulse url>/login' \

-H 'accept: application/json, text/plain, */*' \

-H 'content-type: application/json' \

--data-raw '{"email":"<username>","password":"<base64 encoded password>"}'

Replace the following placeholders:

• <pulse_url> — the URL of your Pulse environment
• <username> — your registered Pulse user email
• <base64_encoded_password> — your base64-encoded password

Example:

curl -i 'http://example.com/login' \

-H 'accept: application/json, text/plain, */*' \

-H 'content-type: application/json' \

--data-raw '{"email":"john.doe@example.com","password":"<password_placeholder>"}'

3. After executing the command, you’ll receive a response similar to the following:

HTTP/2 200

date: Thu, 13 Jun 2024 05:17:07 GMT

content-type: application/json; charset=utf-8

content-length: 63

server: nginx

access-control-allow-origin: *

x-frame-options: DENY

x-content-type-options: nosniff

set-cookie: jwt=<jwt_token>; Max-Age=900; Path=/; Expires=Thu, 13 Jun 2024 05:32:07 GMT

etag: W/"3f-Y6s9mpm2ANCRhWr9ueS4XY2nCP8"

​

{"message":"Authentication successful!","data":{"role":"e30="}}

4. Copy the value of the JWT token and note down the role.

Set Up the Cookie Modifier Plugin

To use the GraphQL interface, configure your browser with the JWT token.

1. Install a cookie modifier plugin (for example, EditThisCookie for Chrome or Cookie Manager+ for Firefox).

2. Add the following cookies:

   • jwt: Paste the JWT token obtained from the login response.
   • Any additional cookies required for your Pulse setup.

Access the GraphQL Playground

1. Open your web browser.
2. Navigate to:

http://<pulse_url>/graphql

Replace <pulse_url> with your actual Pulse API URL.

If the cookies are valid, the GraphQL Playground opens successfully.

You can:

• Browse available queries using the Documentation Explorer panel on the right.
• Use the Search Schema bar to find specific queries.
• Click Query to view all available API endpoints.

Verify Access

If authentication is successful, you can interact with the Pulse APIs using GraphQL queries.

• Keep your JWT token secure and avoid sharing it.
• Tokens expire periodically; refresh them as required.
• You can also use browser-based tools such as ModHeader or JWT Inspector to inject the token as a request header.

After adding or refreshing the JWT header, reload the page. The Documentation Explorer panel will appear.
