Frequently asked questions
Common questions about connecting Buttondown and Postmark.
Connect your Buttondown and Postmark accounts once, pick a trigger in one app and an action in the other, then map the fields so data flows automatically between them. [3]
Example: when Buttondown's "Watch Events" fires, WEXTL can "Create Domain" in Postmark. Buttondown has 1 trigger (including Watch Events); Postmark has 28 actions (including Create Domain, Create Message Stream, and Create Server). Add filters and transforms between steps when you need them. [1]
Yes — the integration works in both directions. Use each app's triggers to start a workflow and the other app's actions to update it. [2]
No. Buttondown-to-Postmark automations are built visually on the canvas. You can optionally add custom JavaScript with Functions when you need advanced logic. [4]
Yes. Trigger-based automations start the moment Buttondown (or Postmark) fires a new event — webhook-backed apps run within seconds, and polling-only apps re-check on a schedule you control. [7]
A first automation typically takes 5–10 minutes: connect each app's credential once, drop a trigger + action onto the canvas, map the fields, and turn the workflow on.
You can build your Buttondown + Postmark automation on a 3-day trial with every feature unlocked. Cancel anytime. For your protection, a small deposit is charged to your card when your trial starts. It counts toward your first payment and is non-refundable. [8]
