2. Add Synaps element
There is two integration methods : modal or embed
modal : place a button and open the verification flow when user click on the button
embed : integrate directly the verification flow into your interface
Modal integration (verify with Synaps button)
Add the following element to your page to add the button. 
1
<button id="synaps-btn">Verify with Synaps</button>
Copied!
Note that you can also use it as a link

3. Init SDK
To init the Synaps SDK, simply write down the following line in your JS.
session_service must be replaced either by individual or corporate
individual - for know your customer
corporate - for know your business
1
const Synaps = new SynapsClient('session_id', 'session_service');
2
Synaps.init();
Copied!
Get a session_id
To get a session_id you need to create an app on Synaps Manager. Once you selected your service type, you will have to go in your "integration" tab and copy your Api-Key.
The Api-Key MUST NOT be stored in your frontend. You have to store it on your server and never on the client side. The only thing that should be exposed to the user is the session_id.
To create a session_id, you have to call the API related to the service you chose. For instance, if you chose Identity service, go to Identity > Sessions in the documentation.
Know Your Customer -  Session Creation
Sessions
Know Your Business -  Session Creation
Sessions
Once you initliazed your session_id, you will have to init the SDK with your session_id and a session_service.
session_service must be replaced either by workflow or corporate
workflow - for know your customer
corporate - for know your business
By default, the SDK type is set to modal which means that need to implement the Verify with Synaps button to your page to make it work. However, you can set the type to embed, simply by passing it as an option while you declare the SynapsClient.
1
const Synaps = new SynapsClient('session_id', 'session_service');
2
Synaps.init({
3
    type: "embed",
4
})
Copied!
4. Events
Synaps Web SDK (javascript) lets you know when the user has finished the workflow.
Flow finished
On completed onboarding, Synaps will trigger a callback.
1
Synaps.on('finish', () => {
2
    // Do something
3
});
Copied!
5. Customization
Custom colors
We give you the possibility to customize your workflow with your colors. You can set a primary color and a secondary color, it will create a verification flow tailored to your compliance needs and your brand.
To add primary and secondary colors, simply add colors with primary and secondary inside without the hashtag '#'.
1
const Synaps = new SynapsClient('session_id', 'session_service');
2
Synaps.init({
3
    type: "embed",
4
    colors: {
5
        primary: "212b39",
6
        secondary: "ffffff",
7
    }

Custom Element ID
If for some reason you need to bind our workflow on other element ID, you can.
Simply add, element_id as an option and it will automatically bind it.
1
const Synaps = new SynapsClient('session_id', 'session_service');
2
Synaps.init({
3
    type: "modal",
4
    element_id: "synaps-identity-btn"
5
})

Custom language
You can set a predefined language for your user. Synaps already take advantage of browser language to display the relevant language to the end-user but if your user has set up a language option to your website, you can definitely pass it as an option.

Synaps.init({
2
    lang: "fr" // fr, en,
3
})
