# post\_\_register

`POST /register`

*Register Bridge Node*

Register a new bridge node with the Flashgate platform using cryptographic signature verification for authentication.

This endpoint allows bridge nodes to register themselves with the platform without requiring traditional authentication. Instead, it uses RSA signature verification to ensure the request comes from an authorized organization key.

**Key Features:**

* Cryptographic signature verification using RSA keys
* Automatic node-key association upon successful registration
* Support for multiple cloud providers (AWS, GCS, Azure, S3-compatible)
* Node status and region tracking
* Version information capture for compatibility monitoring

**Authentication:**

* No traditional authentication required
* Uses RSA signature verification for security
* Signature must be generated using a valid organization private key
* Timestamp validation prevents replay attacks

**Supported Providers:**

* `S3`: AWS S3 and S3-compatible services
* `GCS`: Google Cloud Storage
* `AZURE`: Azure Blob Storage

**Validation:**

* All required fields must be present
* Provider type must be valid
* Signature must be cryptographically valid
* Timestamp must be recent to prevent replay attacks

#### TypeScript Client Library

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.flashback.tech/support-reference/platform-api-reference/storage-apis/node-registration/post__register.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
