JavaScript API functions

Switch to

JavaScript API version 6

Changelog

In this release, we added ShowpadLib.trackEvent().

Usage

The methods listed below are all available on the window.ShowpadLib object after page load. Simply call the desired method with the correct parameters.

When window.ShowpadLib is created and ready to go, the method window.onShowpadLibLoaded() will be called (if it exists).

Have a look at the examples to get some more context.

Methods

All methods returning a boolean will return true when the call was executed successfully and return false when something went wrong. The method returns false when a required parameter was not set or when the method was called again before the previous method was completed. Some methods return full objects or single values like getUserInfo() or getVersion()

getVersion

Returns the version of the integration. If this function does not exist, we can assume that version 2 is available.


let version = null;
if (typeof window.ShowpadLib.getVersion === 'function') {
    version = window.ShowpadLib.getVersion(); // Would be 6 in this case.
}
else {
    version = 2;
}

getUserInfo

Returns the information of the active user.

const userInfo = window.ShowpadLib.getUserInfo();

// userInfo will look like this:
const userInfo = {
    email: 'user@company.com',
    id: '123',
    user_name: 'user@company.com',
    full_name: 'Firstname Lastname'
};

getDeviceInfo

Returns the information of the current device. The locale value is a 2-letter code following the ISO 639-1 standard. The app is one of the following values: web, ios, android, windows. It represents the app where this HTML Content is currently being viewed.

const deviceInfo = window.ShowpadLib.getDeviceInfo();

// userInfo will look like this:
const deviceInfo = {
    locale: 'en', // language of the device, following ISO 639-1
    app: 'web' // The app
};

hasFeature

Use this method to know if a specific feature is supported on the app your content is running in.

This method will (synchronously) return:

The list of features can be found in the table below.

Key Description
shareEmail Share content by sending an email. Useful in combination with the share() method
shareLink Share content by generating a link. Useful in combination with the share() method
collections Add content to a collection. Useful in combination with the addAssetsToCollection() method
if (window.ShowpadLib.hasFeature('shareLink')) {
    // The feature "shareLink" is supported on this platform.
}

trackEvent

Track an event in your Experience App. This is used to track how conversations are happening within the experience.
⚠️ At this point you cannot yet access the data you track in an Experience App.

The method accepts a single event or an array of events. The order of the array is the order they are tracked in.

const event = {
        type: 'node-node',
        touchpoint: {
            id:  'someTouchpointUUID',
            name: 'Case Studies',
            url: 'https://www.showpad.com', // Only in case of a url, not included otherwise
            sourceId: 'someSourceTouchpointUUID',
            sourceName: 'Costs',
            destinationId: 'someTouchpointUUID',
            destinationName: 'Cost containment'
        }
    };
ShowpadLib.trackEvent(event); // Track a single event
ShowpadLib.trackEvent([event, ...]); // Track multiple events

share

Shows a modal view to share contents. The provided assets will be added so they can be shared.

The type of the modal is either email or link.

If some of the assets are not shareable (expired, deleted, unshareable, …), the modal will still be shown, but the callback function will be called with result partial. In this case, the Showpad client will show a warning message to the user that some content cannot be shared.

If none of the provided assets can be shared, a warning will be shown, but no sharing modal will be displayed and the result will be error

const assetSlugs = ['asset1-slug','asset2-slug'];
const type = 'email'; // Can be 'email' or 'link'.
if (window.ShowpadLib.share(type, assetSlugs, callbackFn)) {
    // Call went through, callbackFn will be called.
}
else {
    // Something went wrong or the given type is not supported on this app.
}

function callbackFn (result) {
    if (result == 'success') {
        // all assets were added to the share dialog and the dialog is shown
    }
    else if (result == 'partial') {
        // some assets were not added to the share dialog, because they could be expired, unshareable, deleted, ...
        // the share-dialog is shown
    }
    else if (result == 'error') {
        // no assets were added and the dialog is NOT shown
    }
    else {
      // null was returned, something went wrong
    }
}

getAssetPreviewUrl

Returns the url with which the asset preview image can be loaded. The assetId is always required. The assetSlug is also required on mobile.

var assetId = 'asset1-id';
var assetSlug = 'asset1-slug';
var size = 400;
var imageEl = document.getElementById('image');
imageEl.src = ShowpadLib.getAssetPreviewUrl(assetId, assetSlug, size);

// The asset preview image should now be loaded in the image element.

getAssetsByTags

Invokes the callback function with a list of assets that have all the given tags. This function works offline.

var tags = ['Tag 1','screen-15','nl'];
if (ShowpadLib.getAssetsByTags(tags, callbackFn)) {
    // Call went through, callbackFn will be called
}
else {
    // Something went wrong
}

function callbackFn (assets) {
    if (assets) {
        // Assets might look like this:
        const assets = [
                {
                    "id": "abc123", // Local id to the device
                    "slug": "bdfklje739v930g0d",
                    "name": "my_brochure.pdf",
                    "displayName": "My Brochure fo 2017.pdf",
                    "type": "document",
                    "description": "A description", // Can be null
                    "permissions": {
                        "share": true, // File can be shared
                        "annotate": true, // File can be annotated
                        "download": true // File can be downloaded
                    },
                    "tags": ["Tag 1","screen-15","nl"],
                    "previewUrl" : "https://endpoint/asset/abc123/preview", // Same as response from getAssetPreviewUrl
                },
                ...
            ];
    }
    else {
      // null was returned, something went wrong
    }
}

getAssetsInFolder

Invokes the callback function with a list of assets that can be found in the given folder. This function works offline.

Note: this will not work recursively and will only return actual assets. So it doesn’t return values from deeper levels nor will it return folders.

var folder = 'xyz2250'; // last part from showpad://folder/xyz2250, this can be the id or slug.
if (ShowpadLib.getAssetsInFolder(folder, callbackFn)) {
    // Call went through, callbackFn will be called
}
else {
    // Something went wrong
}

function callbackFn (assets) {
    if (assets) {
        // Assets might look like this:
        const assets = [
                {
                    "id": "abc123", // Local id to the device
                    "slug": "bdfklje739v930g0d",
                    "name": "my_brochure.pdf",
                    "displayName": "My Brochure fo 2017.pdf",
                    "type": "document",
                    "description": "A description", // Can be null
                    "permissions": {
                        "share": true, // File can be shared
                        "annotate": true, // File can be annotated
                        "download": true // File can be downloaded
                    },
                    "tags": ["Tag 1","screen-13"],
                    "previewUrl" : "https://endpoint/asset/abc123/preview", // Same as response from getAssetPreviewUrl
                },
                ...
            ];
    }
    else {
      // null was returned, something went wrong
    }
}

getAssetsByQuery

Invokes the callback function with a list of assets that match with the given query. This function works offline and thus cannot search within documents.

var query = 'onepager';
if (ShowpadLib.getAssetsByQuery(query, callbackFn)) {
    // Call went through, callbackFn will be called
}
else {
    // Something went wrong
}

function callbackFn (assets) {
    if (assets) {
        // Assets might look like this:
        const assets = [
                {
                    "id": "abc123", // Local id to the device
                    "slug": "bdfklje739v930g0d",
                    "name": "featured_product_onepager.pdf",
                    "displayName": "My Brochure fo 2017.pdf",
                    "type": "document",
                    "description": "A description", // Can be null
                    "permissions": {
                        "share": true, // File can be shared
                        "annotate": true, // File can be annotated
                        "download": true // File can be downloaded
                    },
                    "tags": ["Tag 1","screen-15","nl"],
                    "previewUrl" : "https://endpoint/asset/abc123/preview", // Same as response from getAssetPreviewUrl
                },
                ...
            ];
    }
    else {
      // null was returned, something went wrong
    }
}

getAssetFileUrl

Returns the url with which the asset file (the video, image, pdf,…) can be fetched. The assetId is always required. The assetSlug is also required on mobile.

var assetId = 'asset1-id';
var assetSlug = 'asset1-slug';
var videoEl = document.getElementById('video');
videoEl.src = ShowpadLib.getAssetFileUrl(assetId, assetSlug);

// The asset data should now be loaded in the video element.

getCollections

Invokes the callback function with a list of collection data ([{ id, name }]) or null when something went wrong.

if (window.ShowpadLib.getCollections(callbackFn)) {
    // Call went through, callbackFn will be called.
}
else {
    // Something went wrong
}

function callbackFn (collections) {
    if (collections) {
        // Collections might look like this:
        const collections = [
                {
                    id: '1',
                    name: 'Collection Name 1',
                },
                {
                    id: '2',
                    name: 'Collection Name 2'
                }
            ];
    }
    else {
      // null was returned, something went wrong
    }
}

openCollection

Shows a modal view with the contents of the collection. This view allows for the collection to be shared

const collectionId = '...' ;
if (window.ShowpadLib.openCollection(collectionId)) {
    // Modal will be opened
}
else {
    // Something went wrong
}

createCollection

Creates a new collection with the specified name, will invoke the callback function with the id of the new collection or null when an error occured

const name = 'My Collection Name';
if (window.ShowpadLib.createCollection(name, callbackFn)) {
    // Call went through, callbackFn will be called.
}
else {
    // Something went wrong
}

function callbackFn (collectionId) {
    if (collectionId) {
        // Do something with collection id
    }
    else {
       // Something went wrong
    }
}

addAssetsToCollection

Shows the modal which prompts the user the select the collection to add the assets to.
Will call the callback method with the id of the collection the assets were added to or null if the flow was canceled or an error occured

const assets = [];
assets.push('asset1-slug');
assets.push('asset2-slug');
if (window.ShowpadLib.addAssetsToCollection(assets, callbackFn)) {
    // Call went through, modal will be shown.
    // callbackFn will be called
}
else {
    // Something went wrong
}

function callbackFn (collectionId) {
    if (collectionId) {
        // Assets were added to the collection with provided collectionId
    }
    else {
       // Something went wrong or the user canceled the flow or
       // none of the given asset-slugs were found.
    }
}

addAssetsToCollectionWithId

Will add the given assets to the collection with the given id. If the collection does not exist, nothing will happen.

const collectionId = '...';
const assets = ['asset1-slug', 'asset2-slug'];
if (window.ShowpadLib.addAssetsToCollectionWithId(collectionId, assets, callbackFn)) {
    // Call went through, callbackFn will be called
}
else {
    // Something went wrong
}

function callbackFn (collectionId) {
    if (collectionId) {
        // Assets were added to the collection with provided collectionId
    }
    else {
       // Something went wrong or the user canceled the flow
    }
}

clearCollection

Removes all the items from the given collection

const collectionId = '...';
if (window.ShowpadLib.clearCollection(collectionId)) {
    // Call went through, items will be cleared
}
else {
    // Something went wrong
}

getShowpadApi

Invokes the callback function with an object with the required information to do an HTTP request to the Showpad API.

If the Showpad API returns a 401, it means your access token has expired, and you’ll need to request a new one. Do this using the refreshShowpadApi() method.

if (window.ShowpadLib.getShowpadApi(callbackFn)) {
    // Call went through, callbackFn will be called
}
else {
    // Something went wrong
}

function callbackFn (apiConfig) {
    if (apiConfig) {
        // apiConfig can look like this:
        const apiConfig = {
            accessToken: 'xyz',
            url: 'https://subdomain.showpad.biz', // no trailing slash
            error: null // or a string with the actual error
        };

        if (apiConfig.accessToken && apiConfig.url) {
            // Do an api-call
        }
        else if (apiConfig.error) {
            if (apiConfig.error === 'unavailable') {
                // no api key available
            }
            else {
                // something else went wrong
            }
        }
        else {
            // Something went wrong
        }
    }
    else {
       // Something went wrong or the user canceled the flow
    }
}

refreshShowpadApi

This method will refresh the Showpad access token and call the callback function with the same object as the getShowpadApi call

function doApiCall (url, config) {
    fetch(url, config)
            .then(response => {
                if (response.status < 200 || response.status >= 400) {
                    const error = new Error();
                    error.statusCode = response.status;
                    throw error;
                }
            })
            .catch(onApiCallFailed);
}
function onApiCallFailed (error) {
    if (error.statusCode === 401) {
        // Unauthorized, let's refresh the token
        refreshToken(url, config);
    }
}

function refreshToken (url, config) {
    if (window.ShowpadLib.refreshShowpadApi(apiConfig => {})) {
        // Call went through, callbackFn will be called
    }
    else {
        // Something went wrong
    }

    function callbackFn (apiConfig) {
        if (apiConfig) {
            // apiConfig can look like this:
            const apiConfig = {
                accessToken: 'xyz',
                url: 'https://subdomain.showpad.biz', // no trailing slash
                error: null // or a string with the actual error
            };

            if (apiConfig.accessToken && apiConfig.url) {
                // Refresh succeeded, retry the failed call.
                config.headers['Authorization'] = `Bearer ${apiConfig.accessToken}`;
                doApiCall(url, config);
            }
            else if (apiConfig.error) {
                if (apiConfig.error === 'unavailable') {
                    // no api key available
                }
                else if (apiConfig.error === 'expired') {
                    // Refresh Token has expired, no further calls can be made.
                }
                else {
                    // Something went wrong
                }
            }
            else {
                // Something went wrong
            }
        }
        else {
           // Something went wrong
        }
    }
}

getSalesforceApi

Invokes the callback function with an object with the required information to do an HTTP request to the Salesforce API.

If the Salesforce API returns a 401, it means your access token has expired, and you’ll need to request a new one. Do this using the refreshSalesforceApi() method.

if (window.ShowpadLib.getSalesforceApi(callbackFn)) {
    // Call went through, callbackFn will be called
}
else {
    // Something went wrong
}

function callbackFn (apiConfig) {
    if (apiConfig) {
        // apiConfig can look like this:
        const apiConfig = {
            accessToken: 'xyz',
            url: 'https://login.salesforce.com', // no trailing slash
            error: null // or a string with the actual error
        };

        if (apiConfig.accessToken && apiConfig.url) {
            // Do an api-call to Salesforce
        }
        else if (apiConfig.error) {
            if (apiConfig.error === 'unavailable') {
                // no Salesforce access token available
                // Possibly, the user is not connected to Salesforce.
            }
            else {
                // something else went wrong
            }
        }
        else {
            // Something went wrong
        }
    }
    else {
       // Something went wrong or the user canceled the flow
    }
}

Particularities with the Salesforce API and HTML Content

To call an api on a different domain (eg. “https://login.salesforce.com”), that service needs to have CORS enabled. More info about CORS or (Cross-Origin Resource Sharing) can be found here .

Salesforce has a specific settings-page to enable specific domains for your Salesforce instance. Salesforce requires this to be an “https://”-url. The problem is that your HTML Content is also rendered in our mobile apps, and they don’t use an “https://”-scheme, but something specific for the platform (eg. “ms-appx-package://” on Windows).

So calling the Salesforce API directly from your HTML Content, will probably result in a CORS error by Salesforce.

To circumvent this, we suggest to proxy all api-calls to Salesforce through an iframe. This iframe would link to a webpage hosted on a CORS-enabled domain. The javascript in the HTML Content would just call some javascript in that iframe, which would send it through to Salesforce and send the response back. The communication between the HTML Content and the iframe needs to happen with “postMessage” https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage.

The diagram below might make things more clear.

refreshSalesforceApi

This method will refresh the Salesforce access token and call the callback function with the same object as the getSalesforceApi call.

function doSalesforceApiCall (url, config) {
    fetch(url, config)
            .then(response => {
                if (response.status >= 200 && response.status < 300) {
                    return response;
                }
                const error = new Error();
                error.statusCode = response.status;
                throw error;
            })
            .catch(onSalesforceApiCallFailed);
}
function onSalesforceApiCallFailed (error) {
    if (error.statusCode === 401) {
        // Unauthorized, let's refresh the token
        refreshSalesforceToken(url, config);
    }
}

function refreshSalesforceToken (url, config) {
    if (window.ShowpadLib.refreshSalesforceApi(apiConfig => {})) {
        // Call went through, callbackFn will be called
    }
    else {
        // Something went wrong
    }

    function callbackFn (apiConfig) {
        if (apiConfig) {
            // apiConfig can look like this:
            const apiConfig = {
                accessToken: 'xyz',
                url: 'https://login.salesforce.com', // no trailing slash
                error: null // or a string with the actual error
            };

            if (apiConfig.accessToken && apiConfig.url) {
                // Refresh succeeded, retry the failed call.
                config.headers['Authorization'] = `Bearer ${apiConfig.accessToken}`;
                doApiCall(url, config);
            }
            else if (apiConfig.error) {
                if (apiConfig.error === 'unavailable') {
                    // no Salesforce access token available
