Run a process model through a link (link, button) in the email

A link in an email can not trigger a POST API call. And to call Appian, authentication is required.

One option might be to reply by email and a specific keyword. That email would start a process.

Another option is to create an Appian Portal which accepts a unique identifier sent by email. On this portal these external users could approve or reject.

Stefan, 

Do you have tips for how to insert/extract custom property fields from emails? I'm running into a similar manner as the original poster, but I'm having a very difficult time trying to get the information out of the email. I see in the documentation about retreiving custom properties, but nothing about how to actually implant and/or use them in the email itself. Any help/tips?

I am also having a difficult time with splitting the body information. Using any of the body properties includes the company footer in what is stored in the variable being used to hold the body. 

As an email has zero structure, there is no good or fool proof way of doing this.

What is your concrete use case? If it is about requesting data from a non-Appian user, did you consider Portals?

Currently, it is all POC and being investigated/conisdered. But from my understanding with the clients, it is very similar to the original post. The client does not see a nessecity for certain users to always have to login to Appian in order to approve/deny/reject/etc certain tasks or updates, and wanted it explored for if there is a way to do so using email. I know the send/receive email sections of the Appian documentation mention using custom properties, but I don't see any information about how to correctly set them up or retreive them. It's mentioned at the bottom of this article here, at the very least.

docs.appian.com/.../Receive_Message_Event.html

I assume these custom properties are email headers.

Do you act in a highly regulated environment? If yes, then an approval by email is probably not a good idea.

Go through the following URL - https://docs.appian.com/suite/help/23.1/Receive_Message_Event.html#message-properties

Basically you need to configure the receive message event in the Start node as following.

With Email message types, key-value pairs are treated as custom properties.

To obtain the value of a key specified in a message, the name of the key should be included in the definition of a mapping. For example, if the key-value pair [incidentId =222100] is sent in an email message, you can capture incidentId in a receive message event by creating a mapping with the following definition:

msg!properties.incidentId

Include [incidentId = <value>] in either subject or email body

Stefan,

I understand it's probably not a good idea. But at this point currently, I'm mostly just tasked with checking if it can be done. Even if it's not being implemented, I'm too far into it now myself, that I want to see it through to the end of even being possible. I appreciate the concern and warnings regarding best practices.

Abhay,

That's the information I was looking for! I had all of my input mapped in the process model, but I couldn't get any of the information out of the body. Turns out I was setting up my values wrong, I was usnig colons instead of equal signs. Thank you so much, I couldn't find any information in the documentation about how to actually set up custom properties, just how to call them.
