DialogFlow and Telegram getFile API

[joaquim_c]

Hello, everyone.

I'm currently looking for a way to use the Telegram getFile API through DialogFlow in my fulfillment function. But with no sucess.

I found this post with a similar question in the old DialogFlow ES Community Group, but the answer given by Jinjun Q doesn't seem to respond correcly my question. The question is: is there a way to make DialogFlow forward non-text messages from Telegram to my fulfillment function? If yes, how is it done?

Thanks in advance

Hey there,

I am not an expert in this area, but have some thoughts based on conversations other community members are having on this topic. To forward non-text messages from Telegram to your Dialogflow fulfillment function, you can follow these steps:

1. Enable Inline Mode: In your Telegram Bot's settings, make sure that inline mode is enabled. This allows your bot to receive all messages, including non-text messages, through the inline query mode.

2. Set Up Inline Query Handling: In your Dialogflow fulfillment code, handle the inline_query event. This event is triggered when a user sends a message, including non-text messages, to your bot in inline mode. You can use the Telegram API to retrieve the necessary information about the non-text message.

3. Extract Relevant Data: Within your fulfillment code, extract the relevant data from the inline query event. For non-text messages, the important information would typically include the file ID or other relevant details about the media sent by the user.

4. Implement getFile API: To retrieve the actual file from Telegram, you can use the getFile API provided by Telegram. Make an HTTP request to the Telegram Bot API's getFile method, providing the file ID obtained in the previous step. This API call will return a file object containing the file's URL and other details.

5. Process the File: Once you have the file URL, you can download or process the file as needed in your fulfillment function. For example, you might want to save the file to your own storage system or perform some analysis or processing on the file.

It's important to note that Dialogflow itself doesn't natively support file uploads or non-text messages. However, by leveraging Telegram's APIs and the inline query functionality, you can extract the necessary information about the non-text message and handle it within your fulfillment code.

Remember to handle any errors that may occur during the API calls and ensure that your fulfillment function is appropriately secured and validated before processing the files.

Hope this helps!
