# Fizzy API Fizzy has an API that allows you to integrate your application with it or to create a bot to perform various actions for you. ## Authentication There are two ways to authenticate with the Fizzy API: 1. **Personal access tokens** - Long-lived tokens for scripts and integrations 2. **Magic link authentication** - Session-based authentication for native apps ### Personal Access Tokens To use the API you'll need an access token. To get one, go to your profile, then, in the API section, click on "Personal access tokens" and then click on "Generate new access token". Give it a description and pick what kind of permission you want the access token to have: - `Read`: allows reading data from your account - `Read + Write`: allows reading and writing data to your account on your behalf Then click on "Generate access token".
Access token generation guide with screenshots | Step | Description | Screenshot | |:----:|-------------|:----------:| | 1 | Go to your profile | Profile page with API section | | 2 | In the API section click on "Personal access token" | Personal access tokens page | | 3 | Click on "Generate a new access token" | Generate new access token dialog | | 4 | Give it a description and assign it a permission | Access token created |
> [!IMPORTANT] > __An access token is like a password, keep it secret and do not share it with anyone.__ > Any person or application that has your access token can perform actions on your behalf. To authenticate a request using your access token, include it in the `Authorization` header: ```bash curl -H "Authorization: Bearer put-your-access-token-here" -H "Accept: application/json" https://app.fizzy.do/my/identity ``` ### Magic Link Authentication For native apps, you can authenticate users via magic links. This is a two-step process: #### 1. Request a magic link Send the user's email address to request a magic link be sent to them: ```bash curl -X POST \ -H "Content-Type: application/json" \ -H "Accept: application/json" \ -d '{"email_address": "user@example.com"}' \ https://app.fizzy.do/session ``` __Response:__ ``` HTTP/1.1 201 Created Set-Cookie: pending_authentication_token=...; HttpOnly; SameSite=Lax ``` ```json { "pending_authentication_token": "eyJfcmFpbHMi..." } ``` The response includes a `pending_authentication_token` both in the JSON body and as a cookie. Native apps should store this token and include it as a cookie when submitting the magic link code. __Error responses:__ | Status Code | Description | |--------|-------------| | `422 Unprocessable entity` | Invalid email address, if sign ups are enabled and the value isn't a valid email address | | `429 Too Many Requests` | Rate limit exceeded | #### 2. Submit the magic link code Once the user receives the magic link email, they'll have a 6-character code. Submit it to complete authentication: ```bash curl -X POST \ -H "Content-Type: application/json" \ -H "Accept: application/json" \ -H "Cookie: pending_authentication_token=eyJfcmFpbHMi..." \ -d '{"code": "ABC123"}' \ https://app.fizzy.do/session/magic_link ``` __Response:__ ```json { "session_token": "eyJfcmFpbHMi..." } ``` The `session_token` can be used to authenticate subsequent requests by including it as a cookie: ```bash curl -H "Cookie: session_token=eyJfcmFpbHMi..." \ -H "Accept: application/json" \ https://app.fizzy.do/my/identity ``` __Error responses:__ | Status Code | Description | |--------|-------------| | `401 Unauthorized` | Invalid `pending_authentication_token` or `code` | | `429 Too Many Requests` | Rate limit exceeded | #### Delete server-side session (_log out_) To log out and destroy the server-side session: ```bash curl -X DELETE \ -H "Accept: application/json" \ -H "Cookie: session_token=eyJfcmFpbHMi..." \ https://app.fizzy.do/session ``` __Response:__ Returns `204 No Content` on success. #### Create an access token via the API You can programmatically create a personal access token using either a session cookie or an existing Bearer token: ```bash curl -X POST \ -H "Content-Type: application/json" \ -H "Accept: application/json" \ -H "Cookie: session_token=eyJfcmFpbHMi..." \ -d '{"access_token": {"description": "Fizzy CLI", "permission": "write"}}' \ https://app.fizzy.do/1234567/my/access_tokens ``` Or with a Bearer token (must have `write` permission): ```bash curl -X POST \ -H "Content-Type: application/json" \ -H "Accept: application/json" \ -H "Authorization: Bearer put-your-access-token-here" \ -d '{"access_token": {"description": "Fizzy CLI", "permission": "write"}}' \ https://app.fizzy.do/1234567/my/access_tokens ``` The `permission` field accepts `read` or `write`. __Response:__ ``` HTTP/1.1 201 Created ``` ```json { "token": "4f9Q6d2wXr8Kp1Ls0Vz3BnTa", "description": "Fizzy CLI", "permission": "write" } ``` Store the `token` value securely — it won't be retrievable again. Use it as a Bearer token for subsequent API requests. ## Caching Most endpoints return [ETag](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/ETag) and [Cache-Control](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Cache-Control) headers. You can use these to avoid re-downloading unchanged data. ### Using ETags When you make a request, the response includes an `ETag` header: ``` HTTP/1.1 200 OK ETag: "abc123" Cache-Control: max-age=0, private, must-revalidate ``` On subsequent requests, include the ETag value in the `If-None-Match` header: ``` GET /1234567/cards/42.json If-None-Match: "abc123" ``` If the resource hasn't changed, you'll receive a `304 Not Modified` response with no body, saving bandwidth and processing time: ``` HTTP/1.1 304 Not Modified ETag: "abc123" ``` If the resource has changed, you'll receive the full response with a new ETag. __Example in Ruby:__ ```ruby # Store the ETag from the response etag = response.headers["ETag"] # On next request, send it back headers = { "If-None-Match" => etag } response = client.get("/1234567/cards/42.json", headers: headers) if response.status == 304 # Nothing to do, the card hasn't changed else # The card has changed, process the new data end ``` ## Error Responses When a request fails, the API response will communicate the source of the problem through the HTTP status code. | Status Code | Description | |-------------|-------------| | `400 Bad Request` | The request was malformed or missing required parameters | | `401 Unauthorized` | Authentication failed or access token is invalid | | `403 Forbidden` | You don't have permission to perform this action | | `404 Not Found` | The requested resource doesn't exist or you don't have access to it | | `422 Unprocessable Entity` | Validation failed (see error response format above) | | `500 Internal Server Error` | An unexpected error occurred on the server | If a request contains invalid data for fields, such as entering a string into a number field, in most cases the API will respond with a `500 Internal Server Error`. Clients are expected to perform some validation on their end before making a request. A validation error will produce a `422 Unprocessable Entity` response, which will sometimes be accompanied by details about the error: ```json { "avatar": ["must be a JPEG, PNG, GIF, or WebP image"] } ``` ## Pagination All endpoints that return a list of items are paginated. The page size can vary from endpoint to endpoint, and we use a dynamic page size where initial pages return fewer results than later pages. If there are more results to fetch, the response will include a `Link` header with a `rel="next"` link to the next page of results: ```bash curl -H "Authorization: Bearer put-your-access-token-here" -H "Accept: application/json" -v http://fizzy.localhost:3006/686465299/cards # ... < link: ; rel="next" # ... ``` ## List parameters When an endpoint accepts a list of values as a parameter, you can provide multiple values by repeating the parameter name: ``` ?tag_ids[]=tag1&tag_ids[]=tag2&tag_ids[]=tag3 ``` List parameters always end with `[]`. ## File Uploads Some endpoints accept file uploads. To upload a file, send a `multipart/form-data` request instead of JSON. You can combine file uploads with other parameters in the same request. __Example using curl:__ ```bash curl -X PUT \ -H "Authorization: Bearer put-your-access-token-here" \ -F "user[name]=David H. Hansson" \ -F "user[avatar]=@/path/to/avatar.jpg" \ http://fizzy.localhost:3006/686465299/users/03f5v9zjw7pz8717a4no1h8a7 ``` ## Rich Text Fields Some fields accept rich text content. These fields accept HTML input, which will be sanitized to remove unsafe tags and attributes. ```json { "card": { "title": "My card", "description": "

This is bold and this is italic.

" } } ``` ### Attaching files to rich text To attach files (images, documents) to rich text fields, use ActionText's direct upload flow: #### 1. Create a direct upload First, request a direct upload URL by sending file metadata: ```bash curl -X POST \ -H "Authorization: Bearer put-your-access-token-here" \ -H "Content-Type: application/json" \ -d '{ "blob": { "filename": "screenshot.png", "byte_size": 12345, "checksum": "GQ5SqLsM7ylnji0Wgd9wNA==", "content_type": "image/png" } }' \ https://app.fizzy.do/123456/rails/active_storage/direct_uploads ``` The `checksum` is a Base64-encoded MD5 hash of the file content. The direct upload endpoint is scoped to your account (replace `/123456` with your account slug). __Response:__ ```json { "id": "abc123", "key": "abc123def456", "filename": "screenshot.png", "content_type": "image/png", "byte_size": 12345, "checksum": "GQ5SqLsM7ylnji0Wgd9wNA==", "direct_upload": { "url": "https://storage.example.com/...", "headers": { "Content-Type": "image/png", "Content-MD5": "GQ5SqLsM7ylnji0Wgd9wNA==" } }, "signed_id": "eyJfcmFpbHMi..." } ``` #### 2. Upload the file Upload the file directly to the provided URL with the specified headers: ```bash curl -X PUT \ -H "Content-Type: image/png" \ -H "Content-MD5: GQ5SqLsM7ylnji0Wgd9wNA==" \ --data-binary @screenshot.png \ "https://storage.example.com/..." ``` #### 3. Reference the file in rich text Use the `signed_id` from step 1 to embed the file in your rich text using an `` tag: ```json { "card": { "title": "Card with image", "description": "

Here's a screenshot:

" } } ``` The `sgid` attribute should contain the `signed_id` returned from the direct upload response. ## Identity An Identity represents a person using Fizzy. ### `GET /my/identity` Returns a list of accounts the identity has access to, including the user for each account. ```json { "accounts": [ { "id": "03f5v9zjskhcii2r45ih3u1rq", "name": "37signals", "slug": "/897362094", "created_at": "2025-12-05T19:36:35.377Z", "user": { "id": "03f5v9zjw7pz8717a4no1h8a7", "name": "David Heinemeier Hansson", "role": "owner", "active": true, "email_address": "david@example.com", "created_at": "2025-12-05T19:36:35.401Z", "url": "http://fizzy.localhost:3006/users/03f5v9zjw7pz8717a4no1h8a7" } }, { "id": "03f5v9zpko7mmhjzwum3youpp", "name": "Honcho", "slug": "/686465299", "created_at": "2025-12-05T19:36:36.746Z", "user": { "id": "03f5v9zppzlksuj4mxba2nbzn", "name": "David Heinemeier Hansson", "role": "owner", "active": true, "email_address": "david@example.com", "created_at": "2025-12-05T19:36:36.783Z", "url": "http://fizzy.localhost:3006/users/03f5v9zppzlksuj4mxba2nbzn" } } ] } ``` ## Boards Boards are where you organize your work - they contain your cards. ### `GET /:account_slug/boards` Returns a list of boards that you can access in the specified account. __Response:__ ```json [ { "id": "03f5v9zkft4hj9qq0lsn9ohcm", "name": "Fizzy", "all_access": true, "created_at": "2025-12-05T19:36:35.534Z", "url": "http://fizzy.localhost:3006/897362094/boards/03f5v9zkft4hj9qq0lsn9ohcm", "creator": { "id": "03f5v9zjw7pz8717a4no1h8a7", "name": "David Heinemeier Hansson", "role": "owner", "active": true, "email_address": "david@example.com", "created_at": "2025-12-05T19:36:35.401Z", "url": "http://fizzy.localhost:3006/897362094/users/03f5v9zjw7pz8717a4no1h8a7" } } ] ``` ### `GET /:account_slug/boards/:board_id` Returns the specified board. __Response:__ ```json { "id": "03f5v9zkft4hj9qq0lsn9ohcm", "name": "Fizzy", "all_access": true, "created_at": "2025-12-05T19:36:35.534Z", "url": "http://fizzy.localhost:3006/897362094/boards/03f5v9zkft4hj9qq0lsn9ohcm", "creator": { "id": "03f5v9zjw7pz8717a4no1h8a7", "name": "David Heinemeier Hansson", "role": "owner", "active": true, "email_address": "david@example.com", "created_at": "2025-12-05T19:36:35.401Z", "url": "http://fizzy.localhost:3006/897362094/users/03f5v9zjw7pz8717a4no1h8a7" }, "public_url": "http://fizzy.localhost:3006/897362094/public/boards/aB3dEfGhIjKlMnOp" } ``` The `public_url` field is only present when the board is published. ### `POST /:account_slug/boards` Creates a new Board in the account. | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | Yes | The name of the board | | `all_access` | boolean | No | Whether any user in the account can access this board.
