pinterest-apilib v1.0.4

Getting Started with Pinterest API

Building

Install

Install the library using npm from: https://www.npmjs.com/package/pinterest-apilib

npm i pinterest-apilib

Requirements

The SDK relies on Node.js and npm (to resolve dependencies). You can download and install Node.js and npm from the official Node.js website.

NOTE: npm is installed by default when Node.js is installed.

Verify Successful Installation

Run the following commands in the command prompt or shell of your choice to check if Node.js and npm are successfully installed:

• Node.js: node --version

• npm: npm --version

Install Dependencies

• To resolve all dependencies, go to the SDK root directory and run the following command with npm:

npm install

• This will install all dependencies in the node_modules folder.

Installation

The following section explains how to use the generated library in a new project.

1. Initialize the Node Project

• Open an IDE/text editor for JavaScript like Visual Studio Code. The basic workflow presented here is also applicable if you prefer using a different editor or IDE.

• Click on File and select Open Folder. Select an empty folder of your project, the folder will become visible in the sidebar on the left.

• To initialize the Node project, click on Terminal and select New Terminal. Execute the following command in the terminal:

npm init --y

2. Add Dependencies to the Client Library

• The created project manages its dependencies using its package.json file. In order to add a dependency on the Pinterest APILib client library, double click on the package.json file in the bar on the left and add the dependency to the package in it.

• To install the package in the project, run the following command in the terminal:

npm install

Initialize the API Client

Note: Documentation for the client can be found here.

The following parameters are configurable for the API Client:

HttpClientOptions

RetryConfiguration

The API client can be initialized as follows:

const client = new Client({
  timeout: 0,
  environment: Environment.Production,
  oAuthClientId: 'OAuthClientId',
  oAuthClientSecret: 'OAuthClientSecret',
  oAuthRedirectUri: 'OAuthRedirectUri',
  oAuthToken: null,
  oAuthScopes: null,
})

Authorization

This API uses OAuth 2 Authorization Code Grant.

Authorization Code Grant

Your application must obtain user authorization before it can execute an endpoint call incase this SDK chooses to use OAuth 2.0 Authorization Code Grant. This authorization includes the following steps

1. Obtain user consent

To obtain user's consent, you must redirect the user to the authorization page.The buildAuthorizationUrl() method creates the URL to the authorization page. You must pass the scopes for which you need permission to access.

const authUrl = client.authorizationCodeAuthManager.buildAuthorizationUrl();

2. Handle the OAuth server response

Once the user responds to the consent request, the OAuth 2.0 server responds to your application's access request by redirecting the user to the redirect URI specified set in Configuration.

If the user approves the request, the authorization code will be sent as the code query string:

https://example.com/oauth/callback?code=XXXXXXXXXXXXXXXXXXXXXXXXX

If the user does not approve the request, the response contains an error query string:

https://example.com/oauth/callback?error=access_denied

3. Authorize the client using the code

After the server receives the code, it can exchange this for an access token. The access token is an object containing information for authorizing client requests and refreshing the token itself.

try {
  const token = await client.authorizationCodeAuthManager.fetchToken(authorizationCode);
} catch(error) {
  // handle error
}

Scopes

Scopes enable your application to only request access to the resources it needs while enabling users to control the amount of access they grant to your application. Available scopes are defined in the OAuthScopeEnum enumeration.

Refreshing the token

An access token may expire after sometime. To extend its lifetime, you must refresh the token.

try {
  const token = await client.authorizationCodeAuthManager.refreshToken();
} catch(error) {
  // handle error
}

If a token expires, an exception will be thrown before the next endpoint call requiring authentication.

Storing an access token for reuse

It is recommended that you store the access token for reuse.

Store the token in session storage or local storage.

Creating a client from a stored token

To authorize a client from a stored access token, just set the access token in Configuration along with the other configuration parameters before creating the client:

const newClient = client.withConfiguration({oAuthToken: token});
