# Certifier API

The Certifier API creates, issues, and sends digital credentials such as certificates and badges to recipients. It applies design templates and credential templates to control how each credential looks and what it contains, and can create, issue, and send a credential in a single call. Credential search, listing, and recipient interaction records round out the issuing workflow.

## For AI agents

Create, issue, and send digital certificates and badges, apply design and credential templates, and track recipient interactions through the Certifier API.

## Scope

Does not handle identity verification, exam proctoring, or course delivery. Use for issuing and sending digital certificates and badges only.

## Capabilities

- Create, issue, and send digital credentials to recipients
- Issue and deliver a credential in a single create-issue-send call
- Search and list issued credentials
- Define credential templates that set each credential's content
- Apply design templates to brand a credential
- Record recipient interactions with issued credentials

## Use cases

### AI Agent Credential Issuing

An AI agent connected through Jentic can award a credential on request: it creates the credential from a template for a named recipient, issues it, and sends it to their email. Certifier can even combine those steps into a single create-issue-send call, so the agent completes the award in one action.

Example prompt: Create a credential from a template for a named recipient, issue it, and send it to their email

### Course Completion Certificates

Reward learners at the end of a course by issuing a certificate tied to a credential template. Certifier populates recipient details from the issue request and delivers the certificate, which suits automated completion flows triggered from a learning platform.

Example prompt: Issue a completion certificate from a program template to a learner and send it to their email

### Branded Credential Design

Keep credentials on-brand by applying a design template to each one. Certifier exposes design templates and credential templates so an integration can select the right look and content before issuing.

Example prompt: List the available design templates and create a credential template that uses a chosen design

### Credential Lookup and Verification Records

Answer recipient questions by searching issued credentials and reading their recorded interactions. Certifier lists credentials and credential interactions so a support workflow can confirm what was issued and whether it was viewed.

Example prompt: Search credentials for a recipient email and return each credential's status and recorded interactions

## Why Jentic

- **Setup:** Wiring Certifier by hand means handling its bearer-token auth and tracking the credential, design, template, and interaction paths yourself. Through Jentic you install once, import Certifier from the API Directory, store the token once, and your agent calls it.
- **Permission scoping:** You choose which Certifier operations the agent may call, such as creating and issuing credentials, so operations like deleting credentials or templates are not included unless you add them.
- **Credential handling:** Your Certifier access token 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 'issue a credential' or 'send a certificate', and Jentic returns the matching Certifier operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

## FAQ

### What authentication does the Certifier API use?

The Certifier API authenticates with a bearer access token sent in the Authorization header, per its OpenAPI spec. You create and manage tokens in the Certifier dashboard, and through Jentic the token is stored encrypted by your own Jentic One instance and injected at call time, so it never appears in the agent's prompt or logs.

### Can I issue and send a certificate in one call with the Certifier API?

Yes. Alongside the separate create, issue, and send operations, the API offers a create-issue-send operation that produces a credential from a template, issues it, and delivers it to the recipient in a single request. This suits fully automated completion flows.

### Is there a Certifier MCP server?

You do not need an MCP server to give your agent the Certifier API. Jentic connects it directly from the API Directory: import Certifier, store your token once, and your agent issues and sends credentials through the operations the API already exposes. Operations are discovered on demand, so no extra tool definitions are loaded into the agent's context.

### Can I limit what my agent is allowed to do with the Certifier API?

Yes. Write a rule that allows only the operations the agent needs, for example creating and issuing credentials, and leave out operations like deleting credentials or templates. The agent can award credentials within those bounds, and every call it makes is logged.

### How do I issue a credential through Jentic with the Certifier API?

Search Jentic for 'issue a credential', which returns the Certifier operation with its input schema, then supply the template and recipient details and the agent runs it. To run it on your own infrastructure, install Jentic One from its GitHub repo.
