How to Launch a Bot via a Link or QR code

You can create a link to start your chatbot flows. When a user follows your link, a messenger chat opens and your trigger flow will launch.

Any user who is not subscribed to the chatbot, but clicks your link, will see the “Get started” button. When the user clicks on the button, the triggered flow will launch, this flow will become the welcome flow.

How link launch works for different messengers

For Facebook users, the flow will start immediately if the user has already subscribed.

For Telegram and Viber users, the flow will start after clicking the "Run" button.

For WhatsApp users, the flow will start after sending the preset text to the chat. When clicking on the link, the user will open a chat with your bot, and the message you entered will be in the text input field. When the user submits it, a flow will start for them.

For Instagram users, you can only send a link to your Instagram business account profile. The link to the flow is not generated, since there is no direct link to direct messages in Instagram.

Choose your chatbot, navigate to the “Bot structure” tab, choose created trigger flow. Click on the drop-down menu and choose “Link to launch a flow.”

You can copy the following link formats.

You can share this link directly or add to your site as hypertext or a button.

Also, you can create a QR code for the link. When a user scans the code they will automatically follow the link.

Creating QR code

A QR code is a barcode that consists of black and white blocks and allows you to encode information, in this case, a link. Information stored in the code can be recognized using a smartphone or tablet - point the camera at the code and a window will appear asking you if you want to open the information in the application.

Under the flow name, click the dropdown menu button, and select "Link to launch a flow." Click on a QR code to download it and save to your device in the JPG file format.

You can also share any chatbot flow so that people can view it without editing. You can share flows as a link or an embedded iframe on your website.
