How It Works?

Picky Assist Connector makes use of the inbuilt Automation Feature of Trello called “Butler” you can create simple or advanced automation using Butler and in the Action you can send a “HTTP Request” from Trello to Picky Assist Connector further in the Picky Assist Connector you can create various Actions like Send A WhatsApp Message, Add User into a WhatsApp Group etc

Watch Video How Butler Works

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;


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

You can get Complete List of Variables Supported by Trello Here https://help.trello.com/article/1157-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.

Creating Cards & Adding Comments in Trello when an Incoming WhatsApp Messages comes

This helps you to automatically create a card in the specific board & list you have configured along with the option to add the incoming message as comment in the specific card under “Activity”

We make use of the Picky Assist Connector “HTTP Request” action to push incoming messages from WhatsApp to Trello Board and this process includes 5 steps as explained below;

1. Generating Trello API Key & Token

The very first step is to generate the API token from your Trello account, make sure the the account you are using having access to the board also note that all comments will be added in the name of the user whom the API is generated, if you wish to track the comments and cards created by our platform then we recommend to create a new user and give a name like “WhatsApp Bot” then generate the API from that specific user

To Generate API Key make login into your trello account then click on this url https://trello.com/app-key in the browser and you will see a screen as shown below;

It will open a new window where you need to scroll down and click on “Allow” button as shown in the below image

You will then able to see a page which display the API Token of your Trello Account as shown in the below image;

Now we have got the API Key & API Token this needs to be saved somewhere as we need this in our next step with the Connector HTTP Trigger Action

2. Finding Trello Board ID & List ID

Now we need trello board id and list id of your trello account to which board we want to create a card and to which list we need to create it

To find the Trello ID & Board ID please open the respective board in a browser then prefix .json at the end of the URL as hit enter

Example : If your trello board direct url is https://trello.com/b/OkGJAEZR/trello-api then make it as https://trello.com/b/OkGJAEZR/trello-api.json and hit the browser it will show you a JSON data as shown in the below image

Now open this url in your browser https://pickyassist.com/app/api/trello/board.php and then copy and paste the code into the textbox and click on “Get Details” button as shown below and wait for few time which shows the Board ID & List ID present in your board

This will show you with all the unique ID of the Board & List you have in that specific board which we need it in the next step

3 Create A Connector

Now we create a new connector which needs to be used to push informations from Picky Assist to Trello Server whenever a new incoming WhatsApp message comes

4. Create Global Webhooks or Smart Reply

Now you need to make use of the Picky Assist Global Webhook or Smart Reply (Smart Actions – Route to Connector” feature to trigger the connector whenever an incoming messages comes to your WhatsApp

Send All Incoming Message to Trello

If you wish to send all incoming whatsapp messages to Trello then you need to make use of Global Webhook and configure the Connector “Connecting URL” as webhook

Send Conditional Message to Trello

If you wish to send only specific message to Trello like message contains “Help, Support, Call me” etc then you need to enable the Smart Replies and configure Smart Actions “Route to Connector” then select the newly created connector

5. Setting Up Connector HTTP Request

Now you need to setup HTTP Request in the Connector so that whenever the connector receives an incoming messages it triggers the HTTP request to Trello for creating a new card or adding a comment into the existing card

Go to the Connector then just send a message to your incoming message this helps you to map the incoming message with the Connector,

After that go to “Steps” and Create a New Step then select Action “HTTP Request” and fill in the below details with real value

Method : POST

URL : https://pickyassist.com/app/api/trello/comment.php


api_keyAPI Key which we generated from the first step https://trello.com/app-key
api_tokenAPI Token we generated in the second step
board_id Board ID to which board you need to add the card, generated in the 3rd step
list_idList unique id to which you want to add the card, generated in the 3rd step
numberWhatsApp number you need to map this dynamically
messageIncoming Message you need to make this dynamically
mediaMedia files if any for incoming, you need to map this dynamically

Click on “Body” tab then select “Query String Form/Data” then key the variables in the left side and right side add the actual values which we have extracted from the above steps

Kindly Note that the Title (Name) of the Card should be the WhatsApp Number in order this to work perfectly, so don’t edit the Title of the Card, if you are creating cards manually then make sure you are inputting WhatsApp number along with country code.

The system automatically creates card with the Title as WhatsApp Number
