Submittable is a submission management, grants, and applications platform used by foundations, nonprofits, corporations, and governments to collect, review, and manage forms, applications, submissions, and awards. Its public REST API (v4, base https://submittable-api.submittable.com) provides read-and-write, programmatic access to account data - submissions and their form-field entries, projects and forms, submitters (users), labels, review team members and assignments, funds and payment distributions, and message attachments. The API uses HTTP Basic Authentication (an account access token sent as the password) and is throttled at roughly 10 transactions per second and 10,000 transactions per hour. API access is enabled per account under More > Integrations > API Access, and Submittable pricing is quote-based (bundled Grant/Application Management and Corporate Social Responsibility products, plus Enterprise) via contact-sales.
