How to integrate Postgrid in automation workflow?
3 simple steps to make your Postgrid connected with other apps in automation workflows on WEXTL. Up to 10 minutes integration set up.
STEP 2
Connect Postgrid
When prompted, authorize access to Postgrid in WEXTL once. Postgrid credentials are encrypted and never shared with WEXTL. Authorization will be reused in any future API calls [3].
WEXTL wants to integrate with your Postgrid account. Approve?
STEP 3
Build a workflow
Build your workflow with Postgrid yourself or with WEXTL® AI Builder. Connect Postgrid to any available integrations [5], or use HTTP node to go beyond them.

How Postgrid connects and integrates with WEXTL
Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever Postgrid app is called in workflows. That allows your marketing automations to run without your attention, per defined schedule [7]. Explore documentation [6] for a detailed list of fields that Postgrid supports.
The following table illustrates what fields Postgrid integration require during authorization flow inside our workflow builder [4].

Connect Postgrid to popular apps on WEXTL
Enter a name of the other app you want to sync with Postgrid below. Click on selected app to explore integration options with Postgrid. If the app you search for is not available in WEXTL yet, you can use HTTP node [10] instead to integrate it directly.
Example automation with Postgrid integration
Select Watch Events trigger from Postgrid - this will be a starting point in your automation. Whenever event happens in Postgrid, workflow will start [7] from Watch Events node.
Search for Create a Contact, connect it as the next step of integration sequence. You can use filters between Watch Events and Create a Contact, so only important data pass from Watch Events to the next step. WEXTL gives you full control over the process of Postgrid automation. All parts of workflow are visible on the canvas [4].
Postgrid on WEXTL has 10 modules for combining marketing automations. Explore Postgrid documentation for more.
Video slide demonstrates how Watch Events and Create a Contact [6] nodes are used in Postgrid workflow.
Frequently asked questions
Common questions about automating Postgrid in your workflows.
Postgrid has 1 trigger, including "Watch Events". Triggers are start points of the workflow, and automations may start from them.
Integration has 9 actions, including "Get a Contact", "Get a Postcard", and "Search Contacts", and more. Refer to our Postgrid Documentation for detailed inputs and outputs.
No. Most automations are built visually on the canvas by picking triggers, actions, and mapping fields. You can add custom JavaScript with Functions when advanced logic is needed — but our customers do that in rare cases [4].
Yes. Connections are authenticated per account, credentials are encrypted at rest, and you can enforce approvals and team-level access controls on any automation.
The Postgrid integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by Postgrid official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.
Absolutely. Where Postgrid provides native webhooks, you can use instant triggers to eliminate polling delay. For custom webhooks, WEXTL offers Custom Webhook node, so you can start automation whenever Postgrid or any other service sends event to webhook URL.
WEXTL is an AI-first visual canvas. The platform allows you to describe automation in plain text — and AI will wire nodes for Postgrid inside the workflow builder [4]. You can also use built-in workflow nodes (AI Agent, Human in the Loop, Condition, Aggregate Results) in pair with Postgrid modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
