TradePending SDK

This javascript interface to TradePending's partner API. You must have a partner agreement with TradePending to use this library.

Breaking Changes from API/SDK v3

• partner_id is now required as a parameter on SNAP.configure, SNAP.configure_with_options, SNAP.next_attribute, SNAP.get_report_url, SNAP.get_report, SNAPes.search, and SNAPes.search_with_options.
• dealer_url and zip_code are now required parameters on SNAP.get_report and SNAP.get_report_url.
• dealer_id is not longer a parameter for SNAP.next_attribute.
• The callback provided to SNAP.configure and SNAP.configure_with_options now is called with callback(err, vehicle) instead of callback(error_or_vehicle_guess_which) for consistency and usability. Other functions like SNAP.next_attribute already functioned this way since v3.

ChangeLog

Typeahead SDK

The Typeahead SDK uses an autocomplete box to allow a user to select a year, make, model, trim quickly.

Additional functions help you ask the user to select additional vehicle attributes, and ultimately generate a TradePending used vehicle value report.

Including

Include as <script> on your site

<script src="https://code.jquery.com/jquery-3.4.1.min.js" integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo=" crossorigin="anonymous"></script>

<link rel="stylesheet" type="text/css" href="https://cdnjs.tradepending.com/stylesheets/snap-typeahead.css">

JQuery (with AJAX support) is required.

The SDK will be made available as the SNAP global variable.

The stylesheet above is some basic CSS that you can use as is or copy and change.

NPM dependency for use with webpack, etc.

npm i --save @tradepending/snap-sdk

require('snap-sdk') exports two variables, SNAP (Typeahead SDK), and SNAPes (Search SDK).

Webpack

The Typeahead SDK can be directly accessed via

const SNAP = require(snap-sdk/dist/snap-typeahead);

The typeahead.js jQuery plugin must be loaded before calling SNAP.configure. How this might be accomplished depends on your setup. The gulpfile.js in this repository includes a minimal webpack example using code from the example/ directory.

Typeahead SDK Usage

Overview:

1. Configure snap by telling it what <input> element to attach autocomplete to, and provide a callback that will be called once the user has selected their year, make, model, trim.
2. Repeatedly next_attribute and present additional choices to the user until the vehicle is fully identified.
3. Open a value report in a new window or iframe, or obtain the report data in JSON format.

Configuration

A css_selector is required to configure the SDK.

SNAP.configure(partner_id, css_selector, callback);

css_selector should uniquely identify the <input> element on the page that you want the vehicle autocomplete box to attach to. Default is #tradepending-vehicle-typeahead.

Additional options can be configured as well.

SNAP.configure_with_options(options, callback);

The options object must include css_selector and partner_id. Optional options are:

• include_new_cars: Allow selection of new cars, not just used. Default is false.
• country: US or CA. Default is US.
• ymm_only: Only select year, make, model (ignore trim). Default is false.
• fuzzy: Use approximate matching for make/model/trim. Default is false.

Additional Attributes

After the user selects their Year/Make/Model/Trim in the autocomplete box, there may be more vehicle attributes that are needed to sufficiently identify the vehicle.

SNAP.next_attribute(partner_id, vehicle, callback)

• partner_id: partner id provided by tradepending.
• vehicle: vehicle object from SNAP.configure or previous SNAP.next_attribute callbacks.
• callback: Handles asking the user for the remaining vehicle attributes.

The callback for SNAP.next_attribute is passed an error and result object. The result object contains the following fields:

• vehicle: the updated version of the vehicle object.
• attribute: the next attribute that needs to be selected.
• choices: all possible choices for the attribute.

Once the vehicle has been fully identified, the attribute and choices fields will not be set on the result object. Additionally, the vehicle object will have been updated to include a vehicle.id that is used when running the used value report.

Trade Value Report

Two report methods are available.

• SNAP.get_report_url(partner_id, dealer_url, vehicle, zip_code, options): Creates the URL used to load the standard SNAP report in a new window or iFrame.

• SNAP.get_report(partner_id, dealer_url, vehicle, zip_code, options, callback): Obtains a JSON version of the report.

• partner_id: partner id provided by tradepending.

• dealer_url: URL of the dealership.

• vehicle: vehicle selected using SNAP.configure and SNAP.next_attribute. The vehicle must be fully selected (vehicle.id exists).

• zip_code: zip code of the dealership or market where the user is looking to trade their vehicle.

• options: Possible options:

  • mileage: User entered mileage to use.

Search SDK

The Search SDK is intended for situations were you want to provide your own UI for selecting vehicles. It provides search methods for determining year, make, model, and trim.

The To perform additional actions like narrowing down vehicle attributes or running a report, the TradePending API must be used.

Including

Include as <script> on your site

<script type="text/javascript" src="https://cdnjs.tradepending.com/javascript/snap-search-v4.js"></script>

The SDK will be made available as the SNAPes global variable.

NPM dependency for use with webpack, etc.

npm i --save @tradpending/snap-sdk

require('snap-sdk') exports two variables, SNAP (Typeahead SDK), and SNAPes (Search SDK).

Webpack

The Search SDK can be directly accessed via

const SNAP = require(snap-sdk/dist/snap-search);

Search SDK Usage

SNAPes.search(partner_id, search_term, callback)

or

SNAPes.search_with_options(options, callback)

the options must include search_term and partner_id. Other options are:

• include_new_cars: Allow selection of new cars, not just used. Default is false.
• country: US or CA. Default is US.
• ymm_only: Only select year, make, model (ignore trim). Default is false.
• fuzzy: Use approximate matching for make/model/trim. Default is false.

callback is called with callback(err, results) where results is an array of vehicles containing year, make, model, trim fields.

Examples

A simple example node server and example client is included in the /example directory.

To run the example server:

DEALER_URL=<dealer-url> PARTNER_ID=<your-partner-id> node example/example_server.js
