Frequently asked questions
Common questions about connecting Captions and Postgrid.
Connect your Captions and Postgrid 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 Captions's "Watch Events" fires, WEXTL can "Cancel a Postcard" in Postgrid. Captions has 1 trigger (including Watch Events); Postgrid has 9 actions (including Cancel a Postcard, Create a Contact, and Create a Postcard). 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. Captions-to-Postgrid 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 Captions (or Postgrid) 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 Captions + Postgrid 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]
