Frequently asked questions
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.
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.
How can I check if a mailer has been delivered?
Use the get_mailer_status tool with the unique mailer ID. It will return the current status, including production phases and the final USPS delivery confirmation when available.
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.
How does AutoGen connect to MCP servers?
Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call Poplar tools during their conversation turns.
Can different agents have different MCP tool access?
Yes. AutoGen's role-based architecture lets you assign specific MCP tools to specific agents, so a querying agent has different capabilities than a reviewing agent.
Does AutoGen support human approval for tool calls?
Yes. Configure human-in-the-loop mode so agents pause and request approval before executing sensitive MCP tool calls.
