How to Add Dynamic Caption When Sending Image to Telegram via HTTP Request

[nashwasabila11 (Fathi Nashwa Sabila)]

Hi everyone,

I’m currently building a UiPath automation that:

1. Reads data from an Excel file
2. Takes a screenshot of a specific sheet or data
3. Sends the image to a Telegram group using the HTTP Request activity

So far, the image is successfully sent to Telegram.
Now, I want to add a caption below the image, which includes a summary automatically generated from the Excel data. This summary is generated by UiPath using data from the Excel file (e.g., reading with Excel activities and processing the values).

My questions:

1. How can I attach a dynamic caption to the image when sending it via HTTP Request?
2. Can I just store the generated string in an Assign activity and pass it as a caption parameter in the HTTP Request?
3. Can I also use parse_mode = Markdown to format the caption nicely on Telegram?

Thanks in advance for your help!

Hi @nashwasabila11

have you tried doing the operations you stated in your below points 2) and 3)?

1. Can I just store the generated string in an Assign activity and pass it as a caption parameter in the HTTP Request?
2. Can I also use parse_mode = Markdown to format the caption nicely on Telegram?

Does it accept the same? ideally, it should work when you send it as parameters.

@nashwasabila11

adding caption is possible as per api

parsing is available for message but not for image

cheers

looks like both are available for use for send photo functionality, but attribute is “parsemode” without underscore.
