## Challenges Tray.ai solves

### Keeping BlackLine credentials out of logs

A raw API call usually means pasting a key or token into the request, where it ends up in step inputs, logs, and screenshots.

**How Tray.ai helps:** Store BlackLine credentials once as a Tray.ai authentication and reference them from the HTTP Connector. Tray.ai masks authentication values in logs, so the secret never shows up in a step's input or output.

### Going from the BlackLine API docs to a working call

Translating an example request from API docs into a workflow step means copying the method, URL, headers, and body by hand.

**How Tray.ai helps:** Paste a cURL example from the BlackLine API docs into the HTTP Connector and Tray.ai fills in the method, URL, headers, and body for you.

### Handling files and non-JSON responses

Not every API answers in JSON. Some return XML, files, or binary data, or expect a multipart upload.

**How Tray.ai helps:** The HTTP Connector parses JSON and XML responses, returns files you can pass to the next step, and sends multipart form data for uploads.

## Frequently asked questions

### Does Tray.ai connect to BlackLine?

Yes. Tray.ai connects to BlackLine through the HTTP Connector, which calls the BlackLine API directly. Any call the BlackLine API documents can run as a step in a Tray.ai workflow.

### How does Tray.ai authenticate with BlackLine?

The BlackLine API uses OAuth 2.0. You save it once as a Tray.ai authentication, and the HTTP Connector adds it to every request.

### Can I get a dedicated BlackLine connector?

BlackLine runs through the HTTP Connector rather than a dedicated connector. If your team wants one, the Tray.ai connector SDK can build a dedicated BlackLine connector from the BlackLine API.
