FAQ

Questions Poplar owners ask.

  • 01

    How do I get my Poplar Access Token?

    Log in to your Poplar account and navigate to the API Settings or Developer section. You will find your Access Token there. Use a Test Token for development and a Production Token for live mailings.

  • 02

    Can I standardize non-US addresses?

    No, Poplar's address standardization service is specifically designed for US addresses only. For international mailing, ensure your addresses are pre-formatted correctly.

  • 03

    How can I check if a mailer has been delivered?

    Use the get_mailer_status capability with the unique mailer ID. It will return the current status, including production phases and the final USPS delivery confirmation when available.

  • 04

    Is the integration secure for customer addresses?

    Absolutely. The integration uses official Poplar Bearer tokens over HTTPS. Your credentials and customer data are encrypted and stored securely within the Vinkius Cloud infrastructure.
