(Beginner) Chatter action to publish an external image to a feed

Question

I'm a beginner to the Salesforce platform and I'm currently integrating my app with the Salesforce Chatter.

I want to create a Chatter Action that does the following:

• shows user an input or select box where user can type/select some value;

• creates a Chatter feed item with the externally loaded image (src of image is dynamically calculated based on the value typed into the input/select field).

I've searched a lot, and it seems that I can build a Canvas App and install it as a Chatter Publisher Action. Is that correct, and is it a way to achieve this task? Can anyone guide me to some (simple) code samples?

Answer 1

There are two possibilities depending on where your Text box and Action needs to happen

1.Assuming your requirement is not to mashup with SFDC UI

Lets say your app is hosted else where and you do not want to bring your page into SFDC ,you can use salesforce REST API to accomplish your requirement .

Platform provides Chatter REST API to push feed into SFDC provided you have set up your app to oauth with SFDC (Via Connected App)

2.Canvas App - If you are trying to mashup your app inside SFDC (UI mash up)

If you want to bring your webpage or app inside SFDC then canvas is tool for it .You will create a connected app and decode SFDC signed request and make an API callout to SFDC once signed request is validated .

There are sample apps in the docs here
