You can find more Videos in Youtube to learn more about how Trello Automation Platform Butler works https://www.youtube.com/results?search_query=trello+butler
Getting Started
The first step is to go to Picky Assist and create a Connector URL and get ready with the Connector URL – Read More on How to Create a Connector
Create A Automation in Trello Butler
Kindly refer the above video’s on how you can create an Automation with Trello Butler, what we will show here how to Set an Action in the Trello which post an event to Picky Assist Connector using the Trello builtin HTTP Request Action
Once A Trigger is Created in the Automation you have to Set an Action, kindly follow the below steps to set a “HTTP Request” as action;
Click on “Content” then move to last option as shown below;


Now Click on “get” and it will show and option “post to” and enter the Connector URL as shown below;

Passing Trello Data Values
In order this automation to work you need to pass the Trello data values in variables appended to the Connector URL or for advanced Users can use JSON as Payload, we will discuss here how to pass the trello values through variables along with the Connector URL
Let’s assume your Connector URL is https://pickyassist.com/beta/url/410474eb24ec757b5545d7c17eaec992c18b
and you need to pass following details to the Picky Assist Connector from your Trello Board
Card Name
Card ID
So we will construct a query as card_name={cardname}&id={cardid} if you wish to add more values you can add & then give a variable name = {bulter variable name} i.e in simple separate a value with &
Now this query needs to be appended to your Connector URL, add ? at the end of the Connecting URL followed by the query as shown below;
https://pickyassist.com/beta/url/410474eb24ec757b5545d7c17eaec992c18b?card_name={cardname}&id={cardid}
So what it do is that whenever an automation triggers the Trello will replace the {cardname} with the actual value and assign this to the variable named “card_name” and post to the URL.
Complete List of Trello Variables

Kindly Note that in order to Send A WhatsApp Message the WhatsApp Number should be saved in your Card along with the Country Code. You can save this as a Card “Title” or in a “Custom Field” Please make sure that the field you save the WhatsApp Number don’t contains any other informations.
