Snapchat Marketing API Documentation

:wrench: Installation

Before you begin, you need to apply for access to the Snapchat Marketing API. Once you are approved, you will be able to register a new application in the 'Business Details' section of your Snapchat Business Account. Notice that the app gets a client ID, secret, and redirect URI required for authenticating with the API.

If you reach an error page when trying to access your Business Account, try disabling any ad-blockers you might have.

After registering your application, you need to install this module in your Node.js project:

npm install node-snapchat-marketing

:arrow_forward: Initialization

In order to use this module, you have to import it in your application first:

const Snap = require('node-snapchat-marketing');

Next, initialize the Snap object with the keys you obtained from the Snapchat business dashboard:

const snap = new Snap({
  client_id: '<CLIENT_ID>',
  client_secret: '<CLIENT_SECRET>',
  redirect_uri: '<REDIRECT_URI>',
});

:key: Authenticating

To make HTTP calls, you need to create an authenticated session with the API.

Step One: Authorize

To obtain an OAuth token, you have to authorize your application with the required scope. The only scope currently available is 'snapchat-marketing-api'.

You are initially required to redirect your user to an authorization URL. You can generate the authorization URL using snap.getAuthorizeUrl. In case you are using Express, your route definition could look as follows:

app.get('/snap/authorize', function(req, res) {
  var url = snap.getAuthorizeUrl('snapchat-marketing-api');
  res.redirect(url);
});

The URL will lead to a page where your user will be required to login and approve access to his/her Snapchat account. In case that step was successful, Snap will issue a redirect to the redirect_uri defined in your Snapchat business account. On that redirect, you will receive a single-use authorization code via a code query parameter in the url.

Step Two: Receive redirect and get an access token

To complete the authorization you now need to receive the callback and convert the given authorization code into an OAuth access token. You can accomplish that using snap.authorization. This method will retrieve and store the access_token, refresh_token, and token expiration date inside the Snap object. Access tokens expire after 1800 seconds (30 minutes).

In Express - If your redirect_uri is https://example.com/snap/callback, your route could look like:

app.get('/snap/callback', (req,res)=>{
  snap.authorization({ authorization_code: req.query.code }, function(err, token){
    console.log("Access token is: " + token.access_token);
    console.log("Refresh token is: " + token.refresh_token);
    console.log("Access token expires in: " + token.expires_in + " seconds");
    res.redirect('/');
  });
});

At this point the access token, refresh token, and token expiration are saved in the snap instance.

You can also set a refresh token globally to avoid re-requesting credentials when you reset your server.

snap.setRefreshToken('<token>');

Step Three: Make HTTP requests to available resources

Now that you are authenticated, you can issue requests using the provided library methods.

For instance, to obtain a list of all available organizations associated with your account, you can use snap.organization.getAll.

snap.organization.getAll(function(err, orgs)
{
  if(err)
    console.log(err);
  else
    console.log(orgs);
});

:books: Library Methods

Authorization

Generate Authorize URL

After getting the authorize url, the user will be redirected to the redirect url with authorization code used in the next function.

snap.getAuthorizeUrl(scope);

Parameter

• Currently, the only available scope is 'snapchat-marketing-api'.

Example

app.get('/snap/authorize', function(req, res) {
  var url = snap.getAuthorizeUrl('snapchat-marketing-api');
  res.redirect(url);
});

Retrieve and store a new access token

snap.authorization(options, callback);

Parameter

• options (object) - Object with attribute authorization_code
• Available options - 'authorization_code': string

Example

app.get('/snap/callback', (req,res)=>{
  snap.authorization({ authorization_code : req.query.code }, function(err, token){
    console.log("Access token is: " + accessToken.access_token);
    console.log("Refresh token is: " + accessToken.access_token);
    console.log("Access token expires in: " + accessToken.expires_in + " seconds");
    res.redirect('/');
  });
});

Me

Get authenticated user

snap.me(callback);

Example

snap.me(function(err, user){
  if(err)
    console.log(err);
  else
    console.log(user);
})

Organization

Get all organizations

snap.organization.getAll(options, callback);

Parameter

• options (object)
• Available options - 'withAdAccounts': boolean

Example

snap.organization.getAll({ withAdAccounts: true }, function(err, orgs){
  if(err)
    console.log(err);
  else
    console.log(orgs);
});

Get organization by id

snap.organization.getById(id, callback);

Example

snap.organization.getById('<organization_id>', function(err, org){
  if(err)
    console.log(err);
   else
    console.log(org);
});

Media

Create a new Media

snap.media.createMedia(media, callback);

Parameter

• media (object) - JS object with options describing type of media to create

Example

const newMedia = {
    media: [
      { name:"Some new media", type:"VIDEO", ad_account_id: myAdAccountId },
    ]
  }

snap.media.createMedia(newMedia, function(err, res){
  if(err)
    console.log(err);
});

ad_account_id - your Snapchat business account id. Can be found on your Snapchat Business Account

Get all Media associated with the authenticated account

snap.media.getAll(adAccountId, callback);

Parameter

• adAccountId - your Snapchat business account id. Can be found on your Snapchat Business Account

Example

snap.media.getAll(adAccountId, function(err,media)
  {
    if(err)
      console.log(err);
    else
      console.log(media);

:bar_chart: Testing

Before you try to run any tests, you MUST go to test/credentials/keys.js and fill in your app credentials.

module.exports = {
  CLIENT_ID: '<your_client_id>',
  CLIENT_SECRET: '<your_client_secret>',
  REDIRECT_URI: '<your_redirect_uri>',
  REFRESH_TOKEN:'<your_refresh_token>'
}

Then, you can execute tests using:

npm run test
