Data and logic

The person does not see these blocks. The app runs them between screens and goes on through the exit the block has chosen: the request succeeded or not, the condition is met or not, the app was opened in Telegram or in a browser.

What the blocks put into variables and how to insert variables into their settings is on the App data page.

HTTP request The "HTTP request" block sends a request to an external API — from the server or from the person's device — and puts the response into variables. Condition The "Condition" block compares variables, tags, the launch source and the link parameter with values and leads through the "Yes" or "No" exit. Launch source The "Launch source" block splits people into branches depending on where the app was opened — Telegram, MAX, the bot web chat, the home screen or a browser. JavaScript The "JavaScript" block runs your code on the person's device — open a link, copy text, read the device theme — and leads through the "Done" or "Error" exit. User tags The "User tags" block adds and removes the app's own tags — everyone who opened the app has them, even without a chatbot.
