<fullname>Lambda</fullname> <p> <b>Overview</b> </p> <p>Lambda is a compute service that lets you run code without provisioning or managing servers. Lambda runs your code on a high-availability compute infrastructure and performs all of the administration of the compute resources, including server and operating system maintenance, capacity provisioning and automatic scaling, code monitoring and logging. With Lambda, you can run code for virtually any type of application or backend service. For more information about the Lambda service, see <a href="https://docs.aws.amazon.com/lambda/latest/dg/welcome.html">What is Lambda</a> in the <b>Lambda Developer Guide</b>.</p> <p>The <i>Lambda API Reference</i> provides information about each of the API methods, including details about the parameters in each API request and response. </p> <p/> <p>You can use Software Development Kits (SDKs), Integrated Development Environment (IDE) Toolkits, and command line tools to access the API. For installation instructions, see <a href="http://aws.amazon.com/tools/">Tools for Amazon Web Services</a>. </p> <p>For a list of Region-specific endpoints that Lambda supports, see <a href="https://docs.aws.amazon.com/general/latest/gr/lambda-service.html/">Lambda endpoints and quotas </a> in the <i>Amazon Web Services General Reference.</i>. </p> <p>When making the API calls, you will need to authenticate your request by providing a signature. Lambda supports signature version 4. For more information, see <a href="https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html">Signature Version 4 signing process</a> in the <i>Amazon Web Services General Reference.</i>. </p> <p> <b>CA certificates</b> </p> <p>Because Amazon Web Services SDKs use the CA certificates from your computer, changes to the certificates on the Amazon Web Services servers can cause connection failures when you attempt to use an SDK. You can prevent these failures by keeping your computer's CA certificates and operating system up-to-date. If you encounter this issue in a corporate environment and do not manage your own computer, you might need to ask an administrator to assist with the update process. The following list shows minimum operating system and Java versions:</p> <ul> <li> <p>Microsoft Windows versions that have updates from January 2005 or later installed contain at least one of the required CAs in their trust list. </p> </li> <li> <p>Mac OS X 10.4 with Java for Mac OS X 10.4 Release 5 (February 2007), Mac OS X 10.5 (October 2007), and later versions contain at least one of the required CAs in their trust list. </p> </li> <li> <p>Red Hat Enterprise Linux 5 (March 2007), 6, and 7 and CentOS 5, 6, and 7 all contain at least one of the required CAs in their default trusted CA list. </p> </li> <li> <p>Java 1.4.2_12 (May 2006), 5 Update 2 (March 2005), and all later versions, including Java 6 (December 2006), 7, and 8, contain at least one of the required CAs in their default trusted CA list. </p> </li> </ul> <p>When accessing the Lambda management console or Lambda API endpoints, whether through browsers or programmatically, you will need to ensure your client machines support any of the following CAs: </p> <ul> <li> <p>Amazon Root CA 1</p> </li> <li> <p>Starfield Services Root Certificate Authority - G2</p> </li> <li> <p>Starfield Class 2 Certification Authority</p> </li> </ul> <p>Root certificates from the first two authorities are available from <a href="https://www.amazontrust.com/repository/">Amazon trust services</a>, but keeping your computer up-to-date is the more straightforward solution. To learn more about ACM-provided certificates, see <a href="http://aws.amazon.com/certificate-manager/faqs/#certificates">Amazon Web Services Certificate Manager FAQs.</a> </p>

Linode API
Cloud Platforms## Introduction The Linode API provides the ability to programmatically manage the full range of Linode products and services. This reference is designed to assist application developers and system administrators. Each endpoint includes descriptions, request syntax, and examples using standard HTTP requests. Response data is returned in JSON format. This document was generated from our OpenAPI Specification. See the <a target="_top" href="https://www.openapis.org">OpenAPI website</a> for more information. <a target="_top" href="/docs/api/openapi.yaml">Download the Linode OpenAPI Specification</a>. ## Changelog <a target="_top" href="/docs/products/tools/api/release-notes/">View our Changelog</a> to see release notes on all changes made to our API. ## Access and Authentication Some endpoints are publicly accessible without requiring authentication. All endpoints affecting your Account, however, require either a Personal Access Token or OAuth authentication (when using third-party applications). ### Personal Access Token The easiest way to access the API is with a Personal Access Token (PAT) generated from the <a target="_top" href="https://cloud.linode.com/profile/tokens">Linode Cloud Manager</a> or the [Create Personal Access Token](/docs/api/profile/#personal-access-token-create) endpoint. All scopes for the OAuth security model ([defined below](/docs/api/profile/#oauth)) apply to this security model as well. #### Authentication | Security Scheme Type: | HTTP | |-----------------------|------| | **HTTP Authorization Scheme** | bearer | ### OAuth If you only need to access the Linode API for personal use, we recommend that you create a [personal access token](/docs/api/#personal-access-token). If you're designing an application that can authenticate with an arbitrary Linode user, then you should use the OAuth 2.0 workflows presented in this section. For a more detailed example of an OAuth 2.0 implementation, see our guide on [How to Create an OAuth App with the Linode Python API Library](/docs/products/tools/api/guides/create-an-oauth-app-with-the-python-api-library/#oauth-2-authentication-exchange). Before you implement OAuth in your application, you first need to create an OAuth client. You can do this [with the Linode API](/docs/api/account/#oauth-client-create) or [via the Cloud Manager](https://cloud.linode.com/profile/clients): - When creating the client, you'll supply a `label` and a `redirect_uri` (referred to as the Callback URL in the Cloud Manager). - The response from this endpoint will give you a `client_id` and a `secret`. - Clients can be public or private, and are private by default. You can choose to make the client public when it is created. - A private client is used with applications which can securely store the client secret (that is, the secret returned to you when you first created the client). For example, an application running on a secured server that only the developer has access to would use a private OAuth client. This is also called a confidential client in some OAuth documentation. - A public client is used with applications where the client secret is not guaranteed to be secure. For example, a native app running on a user's computer may not be able to keep the client secret safe, as a user could potentially inspect the source of the application. So, native apps or apps that run in a user's browser should use a public client. - Public and private clients follow different workflows, as described below. #### OAuth Workflow The OAuth workflow is a series of exchanges between your third-party app and Linode. The workflow is used to authenticate a user before an application can start making API calls on the user's behalf. Notes: - With respect to the diagram in [section 1.2 of RFC 6749](https://tools.ietf.org/html/rfc6749#section-1.2), login.linode.com (referred to in this section as the *login server*) is the Resource Owner and the Authorization Server; api.linode.com (referred to here as the *api se
DigitalOcean API
Cloud Platforms# Introduction The DigitalOcean API allows you to manage Droplets and resources within the DigitalOcean cloud in a simple, programmatic way using conventional HTTP requests. All of the functionality that you are familiar with in the DigitalOcean control panel is also available through the API, allowing you to script the complex actions that your situation requires. The API documentation will start with a general overview about the design and technology that has been implemented, followed by reference information about specific endpoints. ## Requests Any tool that is fluent in HTTP can communicate with the API simply by requesting the correct URI. Requests should be made using the HTTPS protocol so that traffic is encrypted. The interface responds to different methods depending on the action required. |Method|Usage| |--- |--- | |GET|For simple retrieval of information about your account, Droplets, or environment, you should use the GET method. The information you request will be returned to you as a JSON object. The attributes defined by the JSON object can be used to form additional requests. Any request using the GET method is read-only and will not affect any of the objects you are querying.| |DELETE|To destroy a resource and remove it from your account and environment, the DELETE method should be used. This will remove the specified object if it is found. If it is not found, the operation will return a response indicating that the object was not found. This idempotency means that you do not have to check for a resource's availability prior to issuing a delete command, the final state will be the same regardless of its existence.| |PUT|To update the information about a resource in your account, the PUT method is available. Like the DELETE Method, the PUT method is idempotent. It sets the state of the target using the provided values, regardless of their current values. Requests using the PUT method do not need to check the current attributes of the object.| |PATCH|Some resources support partial modification. In these cases, the PATCH method is available. Unlike PUT which generally requires a complete representation of a resource, a PATCH request is is a set of instructions on how to modify a resource updating only specific attributes.| |POST|To create a new object, your request should specify the POST method. The POST request includes all of the attributes necessary to create a new object. When you wish to create a new object, send a POST request to the target endpoint.| |HEAD|Finally, to retrieve metadata information, you should use the HEAD method to get the headers. This returns only the header of what would be returned with an associated GET request. Response headers contain some useful information about your API access and the results that are available for your request. For instance, the headers contain your current rate-limit value and the amount of time available until the limit resets. It also contains metrics about the total number of objects found, pagination information, and the total content length.| ## HTTP Statuses Along with the HTTP methods that the API responds to, it will also return standard HTTP statuses, including error codes. In the event of a problem, the status will contain the error code, while the body of the response will usually contain additional information about the problem that was encountered. In general, if the status returned is in the 200 range, it indicates that the request was fulfilled successfully and that no error was encountered. Return codes in the 400 range typically indicate that there was an issue with the request that was sent. Among other things, this could mean that you did not authenticate correctly, that you are requesting an action that you do not have authorization for, that the object you are requesting does not exist, or that your request is malformed. If you receive a status in the 500 range, this generally indicates a server-side problem. This means that we are having
