Depending on your setup, data should flow between ConvertAPI and Postmark (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect ConvertAPI and Postmark
ConvertAPI + Google Drive + Postmark: When a file is converted using ConvertAPI, it is archived in a specified Google Drive folder, and a confirmation email is sent via Postmark to notify the user of the successful conversion and archival.
Postmark + ConvertAPI + Airtable: When a new email arrives in Postmark containing attachments, those attachments are converted to PDF by ConvertAPI. Then, data about the converted file is extracted and added as a new record in Airtable.
