Example prompt: Call POST `/v4/forms` to create form

### Automated Forms Management

Automate forms operations by combining multiple Submittable Grants Management API endpoints. Agents can list forms and then update form in a single workflow.

Example prompt: Call GET `/v4/forms` to list forms, then verify the result

### AI Agent Integration via Jentic

AI agents discover and call Submittable Grants Management API endpoints through Jentic without managing credentials directly. An agent searches for the required operation by intent, receives the matching endpoint schema, and executes the call with Jentic-managed authentication. This eliminates the need to read API documentation or handle basic tokens manually.

Example prompt: Search Jentic for 'create form', load the operation schema, and execute with Jentic-managed credentials

## Why Jentic

- **Setup:** Wiring the Submittable Grants Management API by hand means setting up its HTTP basic auth with your API key as the username and a blank password, then tracking form and entry ids yourself. Through Jentic you install once, import the Submittable Grants Management API from the API Directory, store the key once, and your agent calls it.
- **Permission scoping:** Submittable puts the form id in the URL path (`/v4/forms/{formId}`), so a rule can pin your agent to one form: it can read and update that form and nothing else. You choose the operations it may call, so destructive ones like deleting a form are not included unless you add them.
- **Credential handling:** Your Submittable basic API key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
- **Discovery method:** Agents search Jentic by intent such as 'create a form' or 'submit an entry', and Jentic returns the matching Submittable operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

## FAQ

### What authentication does the Submittable Grants Management API use?

The Submittable Grants Management API uses HTTP Basic authentication with username and password. Through Jentic, these credentials are stored encrypted in your Jentic One instance and injected at execution time, so raw secrets never enter the agent context.

### Can I create form with the Submittable Grants Management API?

Yes. Use the POST `/v4/forms` endpoint. The API returns structured JSON responses that agents can parse and act on directly.

### What are the rate limits for the Submittable Grants Management API?

Rate limits are not specified in the OpenAPI spec. Check the vendor documentation for current limits. Through Jentic, rate limiting is handled automatically with retry logic built into the execution layer.

### How do I create form through Jentic?

Install the Jentic SDK with pip install jentic, authenticate through Jentic One, the self-hosted execution layer, then search for 'create form'. Jentic returns the matching Submittable Grants Management API operation with its input schema. Load the schema and execute the call - credentials are injected automatically.

### How many endpoints does the Submittable Grants Management API have?

The Submittable Grants Management API exposes 26 endpoints covering forms, entries, funds operations.

### Can I limit what my agent is allowed to do with the Submittable Grants Management API?

Yes. Jentic One is self-hosted by you, so your own rules decide which Submittable operations and credentials the agent can use. Because Submittable puts the form id in the URL path (`/v4/forms/{formId}`), a rule can pin the agent to a single form so it only reads and updates that form and nothing else. You also choose which operations it may call, so destructive ones like DELETE `/v4/forms/{formId}` stay off limits unless you explicitly add them.
