Create PostPulse Webhooks in n8n

If you've followed our previous walk-throughs, you'll understand that sometimes when scheduling a post, something goes wrong; a scheduled post could fail, or stall. And if you're working in a team, then it's important to keep every member of the team up to date on the status of your scheduled posts. While there are lots of ways to send progress reports to your team, for our money, we'd recommend using a webhook. In this article, we're going to walk you through how to set up a PostPulse webhook in n8n.

Step 1: Setup Webhook Node

Add the webhook node in your n8n workflow. In our node, we're going to find two URL's: a test URL, and a production URL, we'll use the production URL for our demonstration.

Our HTTP method is going to be a POST method. And our authentication method is going to be a Basic auth. With a basic auth, we can set up simple credentials using the User and Password fields.

Note: When using the production URL, in order to receive live responses, switch n8n workflow from inactive or unpublished, to active or published.

Step 2: Add Webhook in PostPulse

Once you've set up your webhook in n8n, copy your webhook URL and head over to your PostPulse developer portal. In your dev portal, you'll find the webhook panel to your left.

In the webhooks section, create a new webhook in the application of your choice.

Note: The app chosen must be the exact same application as the one with the PostPulse API key you're using in n8n.

When creating a new webhook, add your webhook URL in the endpoint URL field. In the API key field, you're expected to add a unique key to keep our webhook calls secure. To generate an API key, we're going to head over to base64encode.org to turn our basic auth credentials from n8n into a security key.

To do that, add your basic auth user and password details (for example; user:password) and click on the encode button. It will generate a unique key.

Add the authorization header "Basic" in front of your key, and you now have an API key to use.

Copy and paste this key in the API key field. Once you've done that, all that's left to do is to set up your event subscription; this is where you'll select the kind of event responses you'll like to receive. While you can subscribe to all events, for this demonstration you should subscribe to just 3 events:

• schedule.completed

• schedule.failed

• schedule.partialy_completed

Once you've done that, click on the create webhook button and you're all done. You would have now setup your PostPulse webhook.

If your webhook has been set up successfully, you should be able to view all of your webhooks calls from your webhook dashboard in PostPulse.

And you'll also be able to view the webhook's JSON payload and response.
