Web CMP

Implement a notice on a website using Javascript, as described below.


Latest changes​

The last CMP web version is V32.0.1.

You will find amongst the latest changes:

  • Added a cache for backend calls to improve global navigation performance

  • The ability to manipulate consents of your users without displaying the CMP (e.g, for Youtube, Twitch or Twitter embeddings)

  • The replacement of a Continue without accepting by a clickable cross for users using Italian language to abide the latest Italian regulations.

  • The implementation of the notice has been simplified.

note

You can find more details on Release notes page.


Main steps to implement a web notice​

info

You wish integrate AppConsent into shopify? See the dedicated page: ImplΓ©ment Appconsent with Shopify

1. Implement the notice​

info

Open your HTML code source first.

  1. Go to Notices tab in AppConsent configuration interface
  2. Then under the notice you wish to integrate, copy the integration code using the "Copy" button

Quick start copie code

  1. Finally, paste the code in the <head> tag in your website

2. Add privacy center​

With the GDPR, you have an obligation to provide a way for the user to be able to change their choices at any time and easily. That's why you need to add privacy center kit.

3. Results​

Congratulations! You have now finished setting up the CMP, your code should look like this :

<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">

Migrated your old configuration​

Since version 29.0.0, the implementation of cmp in your website has been simplified. For users who have configured the cmp before this release, we have provided a guide to migrate to the new configuration.

Configuration Migration Guide


Go further​

Now that you have implemented your CMP you can put some extra commands or settings by reading the following instructions.

Passing commands in URL​

You can pass commands to the CMP through the querystring. Querystring commands are evaluated on init.

?ac_cmd=show

The above link would show the CMP on init.

For more specific needs, other orders exist. Please contact the support.

You can also pass parameters to the command with the same mechanism. Parameters are passed as is from the querystring. Consider the following example:

?ac_cmd=show&jumpAt=banner

Commands / CMP Calls​

CMP can be controlled through iAB's __tcfApi global function, as documented.

Custom calls are providen to operate the CMP, like displaying it, activating programmatic consent and so on. All Custom calls are asynchronous functions receiving an error-first callback and optional arguments, as follow:

init​

Init the CMP with AppConsent credentials and additionnal configurations.

argument nametypeoptionalvalue
commandstring'init'
versionnumber2
callbackfunctionfunction(error: Error, state: State)
parameterObjectConfiguration

Callback returns the CMP's state, retrieved from either LocalStorage or server. State contains Consent and Vendorlist. This command performs at most one server call.

Basic Example​
__tcfapi("init", 2, console.log, {
appKey: "YOUR_APPKEY",
});
Basic Example with i18n​
__tcfapi("init", 2, console.log, {
appKey: "123",
i18n: {
buttons_acceptAll: { values: { en: "ACCEPT ALL" } },
},
});
Advanced example with passing ExternalID (UUID key)​
__tcfapi("init", 2, console.log, {
appKey: "appKey",
uuid: "YOUR_ID_ABCD12345678",
debug: true,
storage: true,
i18n: {
banner_title: { values: { fr: "DΓ©mo i18n" } },
buttons_acceptAll: { values: { fr: "DΓ©mo i18n Accept" } },
},
});

Static mode example​

A static example file can be found here: collector-fr.json

show​

Displays the CMP for collecting user consents.

ArgumentTypeOptionalValue
commandstring'show'
versionnumber2
callbackfunctionfunction(error: Error)
parameterObjectShowOption
ShowOption = {
/**
* true - If a consent if present, won't bother the user
* false (default) - Show the banner no matter what
*/
lazy: Boolean,
/**
* null, 'banner'
* 'privacy'
*/
jumpAt: string,
};
Example 1:​
__tcfapi("show", 2, console.log, {
lazy: false,
});
Example 2:​
__tcfapi("show", 2, console.log, {
jumpAt: "privacy",
});

accept​

Registers a full consent on the CMP, as the user would have clicked on the "accept everything" button. The default behavior is to prevent overwriting any existing consent. You can force overwriting by specifying a special force parameter.

Note that no matter the outcome, this call will hide the UI.

ArgumentTypeOptionalValue
commandstring'accept'
versionnumber2
callbackfunctionfunction(error: Error)
parameterObjectAcceptOption
Example:​
__tcfapi("accept", 2, console.log);

deny​

ArgumentTypeOptionalValue
commandstring'deny'
versionnumber2
callbackfunctionfunction(error: Error)
parameter
Example:​
__tcfapi("deny", 2, console.log);

fakedeny​

Forge a deny consentstring and return it to all vendors, without saving it as a user legitimate consent. This is useful to prevent unhonorable vendors from assuming lack of consent is one. This WONT hide the UI.

ArgumentTypeOptionalValue
commandstring'fakedeny'
versionnumber2
callbackfunctionfunction(error: Error)
parameter
Example:​
__tcfapi("fakedeny", 2, console.log);

How heavy is this CMP ?​

We're leveraging chunking to alleviate bandwidth. Code for the UI is only downloaded when user interaction is needed. Besides, we do have a nice size report

Tag managers compatibility​

We've decided to not support directly tag managers, as implementation and usages varies. We strongly encourage you to use the standard TCF v2 API to achieve consent resolution for your tags. But it's very easy to interract with them.

For example, a GTM implementation could look like this, provided we only strive for a full consent:

__tcfapi("getTCData", 2, (tcData, ok) => {
if (ok) {
for (var c in tcData.purpose.consents) {
if (tcData.purpose.consents[c]) {
// Push events to GTM
window.dataLayer.push({ event: "purpose_" + c });
}
}
}
});

Or for Tag Commander:

__tcfapi("getTCData", 2, (tcData, ok) => {
if (ok) {
var tcVars = {};
for (var c in tcData.purpose.consents) {
if (tcData.purpose.consents[c]) {
// Build a TagCommander events object
tcVars["purpose_" + c] = "1";
}
}
// Push events to Tag Commander
window.tcEvents(null, "sfbx_consent_action", tcVars);
}
});

Very simple exemple :

__tcfapi("getTCData", 2, (tcData, success) => {
if (success) {
console.log(tcData.tcString);
} else {
// do something else
}
});

Will output your tcString V2 in your console :

More information in the official IAB Documentation here.

Edition of consents without displaying the CMP​

When you website embeds external integrations (Youtube, Twitch, Twitter, etc.), you may need to modify consents of a user (with their agreement) to give access to this content without redisplaying the CMP. To do this, you can use the updateStatus function. This is how to use it:

__tcfapi('updateStatus', 2, () => {}, [{t: <type>, id: <id>, status: <bool-value> }])

The list of possible types <type> is the following one:

1 - Purpose

2 - Extra purpose

3 - Special feature

4 - IAB vendor

5 - Extra vendor

The ID <id> is the one of the object you want to enable/disable. Its nature depends on the object represented by <type>. You can see the list of available types and IDs for your notice through getTCData call (see usage example here).

The value <bool-value> enables (true) or disables (false) for the tuple (<type>, <id>).

An error will be returned if the consent of the user does not exist yet, of if any of the input combinations (<type>, <id>) does not exist in the array in argument.
