Price an API order before you send it - post the same request body to the estimate endpoint to get the total, a cost breakdown, and whether your balance covers it, with nothing charged or mailed.

How long each field on an API order can be, how characters are counted, when an order is rejected versus a value being shortened, and how %FIRST_NAME% splits a recipient's name.

Find the IDs the API, Zapier, n8n, HubSpot workflows and AI assistants need - a creative's ID, its front and message template IDs, and mailing list IDs - and where your API keys are.
