Signed URLs are valid for three hours Requires the `urls:sign` API key scope. ## OpenAPI ````json POST /signURLs { "openapi": "3.0.3", "info": { "title": "Tulip API", "description": "The Tulip API gives you programmatic access to your Tulip data.\n\n### Query Parameters\n\nSome Tulip API endpoints take parameters specified in the [URL query](https://en.wikipedia.org/wiki/Query_string). In the Tulip API, the URL query is expected to be a list of key-value pairs, with pairs separated by `&`, keys and values separated by `=`, and keys and values being [percent-encoded](https://en.wikipedia.org/wiki/Percent-encoding). Keys are parsed as strings, values *must* be present for each key, and values are parsed as JSON. Simple string values may be specified as-is instead of being JSON-encoded. A query parameter may be specified multiple times, but only the final value will be used. Examples (shown without percent encoding for readability):\n\n * `a=1&b=true&c=\"hello\"` would parse a parameter `a` as the number 1, `b` as the boolean `true`, and `c` as the string `hello`\n * `a=foo&b=\"foo\"` would parse a parameter `a` as the string `foo` and `b` as the string `foo`\n * `data={\"points\":[{\"x\":3,\"y\":4},{\"x\":2,\"y\":-9}]}` would parse a parameter `data` as an object with a single field `points` containing an array with two elements: an object with `x` as the number 3 and `y` as the number 4, and an object with `x` as the number 2 and `y` as the number -9\n * `a=foo&a=bar` would parse a parameter `a` as the string `bar`\n", "termsOfService": "https://tulip.co/tos/", "contact": { "name": "Tulip Interfaces", "url": "https://tulip.co/contact-us/", "email": "sales@tulip.co" }, "version": "3.0" }, "servers": [ { "url": "http://localhost:8088/api/v3", "description": "Cypress Tulip API Server" } ], "paths": { "/signURLs": { "post": { "summary": "Sign cloud storage URLs", "description": "Sign cloud storage URLs.

All requests require the `Authorization` HTTP header with the `Basic` scheme to provide API credentials unless otherwise noted.\n\nAPI tokens can be configured with a set of _scopes_ which determine what parts of the API that specific token has access to. Security best practices dictate that API credentials be given the minimum set of capabilities required to fulfill their intended purpose. For example, an API token created for use in an integration that is only designed to use the Tables API should probably only be given the `tables:read` and `tables:write` scopes. In this way you can minimize risk in the event that API credentials are compromised. API endpoints will document what API token scopes are required to access that endpoint in their descriptions. If a request is made to an endpoint with an API token which does not have the required scopes, the response will be an authorization error.\n" } }, "schemas": { "ApiError": { "x-tulip-visibility": "public", "type": "object", "properties": { "errorCode": { "type": "string" }, "errorUniqueID": { "$ref": "#/components/schemas/RandomSecret" }, "details": { "type": "string" } }, "required": [ "errorCode", "details" ] }, "RandomSecret": { "x-tulip-visibility": "public", "example": "aq21mSKC1rbO87TjC/4Hz2EJHd/v+jxf7MtC315vo0Y", "type": "string", "pattern": "^[a-zA-Z0-9+/]+$" } } } } ````
