How can I resend last message with buttons if the response was invalid?

There is a telegram message with buttons.
User send custom message
I want to catch it and tell him that the message is wrong and resend the same initial message with buttons.

How can I do that?

It sounds like you want to use an “Ask a Question” task, which will validate that the answer is one of the options and repeat the question if the validation does not pass.

Thank you. Yes, this is the good solution, but what if I want to change the button layout? In case of “Ask a Question” task I don’t have an option to set number of rows for the buttons, right?

I see. You can turn a Telegram “Send a Message” into a question with a “Wait for a Response” task immediately after the message you send. This can be configured with validation. However, it does NOT repeat the question. Unfortunately there is not a way to automatically repeat the question using a combination of Send a Message and Wait for a Response.

There might be an imperfect workaround by repeating the question in the custom validation message of the Wait for a Response task.

Yes, it would be great. Because now the chain seems like “Label + send TG message + wait for response [without validation] + parsing answer + go to label”

It is really noisy to implement for every question in the flow…

Maybe you can add toggle for switching between native and inline buttons just for telegram to the “Ask a question?” entity? Would it be difficult to implement?
