Upload image or file via google hangout webhook - webhooks

I needed to upload images via hangout webhook. Is there anyway to don that ?
Please provide api end point through which i can upload images through webhook

I am looking for a solution to this as well. Haven't found it yet, but the workaround I am going with till then is to upload the file on drive/GitHub and sending the link as a text message.

settings in slack that gives you access to the bot [Zapier]

I am new to Zapier. There is some steps in Zap that integrates it with Slack. When someone pushes files from Slack, Slack Bot sends message like "XYZ files have been successfully uploaded to Encompass" but actually the files are not getting uploaded in Encompass.
I am wondering if the Slack Bot sends message but why files are not getting uploaded in Encompass.
Could somebody helps me with this issue? Do I need to do anything in Slack setting to make that work?
But I am not able to see settings in Slack, I can see just Administration.
Thank you in advance! I would really appreciate the help!
I am in need to fix it immediately.

Attach File that was returned in POST call

I have a Podio native webhook that posts to a service we created. That service then returns a PDF. Initially it was attaching the PDF as a file, but it is no longer doing that.
What does the incoming call need to look like to attach that PDF to the Podio item that sent the webhook?
Hope you've used the technique mentioned here - https://developers.podio.com/examples/files ?
The operation would first involve uploading the file and then attaching to an item. Two separate API calls would be required to do so. Later, could you please share the specific error you are facing? Snippets will help too.

Add image as a response in web demo (DialogFlow)

I just want to know if its possible to add images as a response into chatbot web demo. If is not supported, how can I do this? How else can I do it?
As per my knowledge it is not at possible in web demo, you can add images hyperlinks or buttons in your website try exploring custom payload option, where on your website you will have to code by yourself, for the buttons when you send responses as custom payload and divert it to google assistant.
Web demo does not support images or buttons.
You can add some other chat client which supports images, like facebook messenger, slack etc.

I was looking for this feature today morning and realize that unfortunately this doesn't exist. The productsforum # google is full of requests for this feature, see link below for your reference.
