Connecting your accounts

1. Navigate to the Zapier page where you can set up the Zap between Postmark and Outgrow and click on Connect Outgrow + Postmark button.

2. On the configuration page select the trigger that will be activated when a new lead is submitted in Outgrow.


3. In the next step, you need to connect your Outgrow account with Zapier. In case you have an existing Outgrow account connected with Zapier, you can choose that account, else you can add a new account.


4. To connect a new Outgrow account, you will need to plug in the API key for your account. You'll find the key under the API Key Heading in the Settings section of your Outgrow account.


5. Choose the calculator/quiz/poll/graded quiz that you wish to use from the drop-down.


6. Fetch sample leads from Outgrow to test whether or not the connection is successful.


7. In the next step choose the action that needs to be performed when a new lead is sent to Postmark.


8. To get started with Postmark on Zapier, first, you will need to click to connect your Postmark account to use with your Zap.


9. Next, you'll be asked to enter your X-Postmark-Server-Token.


Note: To locate your X-Postmark-Server-Token in your account, login to your Postmark account and select the server you want to connect to Zapier. Then you need to click the "Credentials" tab on the next page that shows and copy the Server API token to your clipboard. Paste your token back into your Zapier account and then “Continue”. If your server token was entered correctly your Postmark account will now be successfully connected. You can now use this account with Zapier.

10. Once your account will be linked you can test the connection.


11. In the next field set up the template that you would like to use.

12. Click Save + Continue.

Now, test the Zap to make sure it works. Once you’re satisfied with the results, new entries from your selected Outgrow calculator or quiz will automatically trigger an email to the collected contact using Postmark.

Note: If you ever want to change this Outgrow and Postmark integration, just go to your Zapier dashboard and tweak anything you like.
