Print and Mail API Services

The government authority in St. Louis, MO needs print and mail API services to establish an automated system for programmatic mail fulfillment. The buyer requires a RESTful API that enables departments to trigger standardized physical mailings from digital systems. The requested scope includes providing both sandbox and production environments, supporting direct PDF uploads, and implementing a dynamic template engine capable of metadata mapping, merge tags, and variable personalization. Additionally, the contractor must deliver an automated pre-send proofing workflow that returns a rendering URL for visual verification, along with robust identity management for departmental budget tracking and data residency compliance. The vendor will perform all work offsite. Only USA organizations located onshore meet the buyer's eligibility criteria. The buyer currently seeks proposals to determine the budget.
