Step 6: Test the Response in Pabbly Connect Dashboard

As we can see, we are done setting up the trigger for Trello and Slack integration. So, let’s test the Trello trigger by adding test card.

Step 7: Set-up a Filter

You must be wondering why we need to add a filter here. The answer to this is, when you create a workflow without a filter the workflow will run repetitively for each card event such as card created, card updated, card deleted etc. So, to prevent this from happening we’ll simply add a filter condition that will only allow newly created cards.

(a) Select Application you want to integrate

Click the plus button next to your trigger window. Next, select the Choose App value as ‘Filter’.

(b) Define Filter Condition & Send Test Request

Now first, select the ‘type: createCard’ response value in the first condition box.

Second, make sure the second box value to be ‘Equal to’.

Lastly, write ‘createCard’ in the third box,

Then, click the ‘Save & Send Request’ button.

Step 8: Add a Delay Function

As you can see adding a card name and adding the other details to that particular card are who different events on Trello. So, when you design the workflow without a delay function that it will separately for each separate event like naming a card, adding the details etc. And to avoid this from happening we are placing a simple delay function in between.

(a) Add Delay

Hit the plus (+) button and then select the choose app field as ‘Delay’. Also, select the delay value as ‘1’ and then click on ‘Save & Send Test Request’.

(b) Check Delay Success

Check whether your delay is working fine or not in the response window.

Step 9: Get Card Details

(a) Click on Card

Next, we need to add the details for the card name. So, click on the created card first.

(b) Add Card Details

Add the card details.

(c) Get Card Details to Send Slack Notifications on New Cards in Trello

Next, click on the plus button and again select the ‘Trello’ app from choose app dropdown. This time select the event as ‘Get Card Details’.

(d) Again Connect with the Same Trello Account

Now, you don’t need to fill in the API key and token. Select the recent credentials from the ‘New Credentials’ list instead.

(e) Map Card ID

Now, map the card id from the previous response.

To map the card id, click on the menu button (i.e. three horizontal lines) next to the field. Then, find and click on the response value from the captured trigger response.

(f) Send Test Request

Further, click the ‘Save & Send Test Request’ button.

Step 10: Setting Action for Trello to Slack Integration

Now, as we have gathered all the data to send notification on Slack from the new Trello card. We can proceed to use this data to perform our action. After that, a notification will be sent on the Slack channel for every new Trello card entry automatically.

Hit the plus button and select the app to integrate here as ‘Slack’.
