LiveCode server as OAuth2 client for APIs?

[Ralf Bitter]

Hi Keith,

using revIgniter you can always hard code the opening
form tag, this way you can use any URL as an action
attribute.

However, your message has prompted me to change the
rigFormOpen() function so that you can override the
current URL with the value of an optional action
attribute included in the second parameter.
So, if you like, you can download the modified
version of the form helper at:

This requires a POST to a Salesforce endpoint, which, if successful redirects to a page on the Salesforce authorisation server to provide login credentials. This is where I’m stuck...
