If an API producer has not shared a spec with you, then creating an API spec in Step 2 is not a declarative process., You can either create the API spec (depending on your background) yourself, enlist your developer, or use a schema builder tool like Swagger Editor to do this. Salesforce can capture these responses from the external web service for use with a tool like Flow Builder. Data is retrieved, created, updated, or deleted by the external web service. The web service returns output based on the API spec. During runtime, flow sends a callout to the web service endpoint.A Salesforce administrator uses Flow Builder to access the invocable flow actions that were registered in Step 4.External Services imports the API spec's operations into your org and makes them available as invocable actions.
#Youtrack rest api registration
A Salesforce administrator declaratively registers the web service and uses both the Named Credential and API spec during the registration process.The endpoint is simply what exposes the web services resources for interaction with External Services. A Salesforce administrator or developer declaratively create a named credential to authenticate the web service endpoint using the URL of the REST-based API provided by the external web service provider.The web service provider (like in our bank web service example) or a developer (or maybe even you) shares a JSON-based API spec that describes the API.In this scenario, think of a REST-based API as specifying a type of contract between the bank (provider) and you (consumer). An external web services provider, such as a bank, hosts its REST-based API.As you work your way through the units in this module, we cover each step in more detail. Notice that while there are 6 steps, the key ones for External Services are 3, 4, and 5. Once registered, you can use tools like Flow Builder to build a flow with the invocable actions of your web service. While we’re looking, though, notice that much of the work to register an external web service of your own is done declaratively via the External Services registration page. It’s time to take a step back and look at the whole picture to understand the interconnected building blocks of External Services. Later on, we have a simple application use case that walks you through the API spec of a web service, registers the operations defined in the schema, and uses Flow Builder to drag-and-drop the newly available actions into a flow. While these terms-OpenAPI specification, API spec, and schema-are geared toward developers, External Services helps bridge the gap between the coding of web services, and automating the access to them. Salesforce Flow includes flows (built with Flow Builder) and processes (built with Process Builder). When the flow runs, it updates the credit terms for the order associated with the account.įlow- A flow is the part of Salesforce Flow that collects data and performs actions in your Salesforce org or in an external system. You register your external service (the credit validation service), External Services converts the service into invocable actions (see definition) for use with a platform tool like Flow Builder, and then you use Flow Builder to create a flow that includes the actions from this outside service into inputs like order amount and credit terms. Let’s say you want to connect to a credit service that determines if credit is extended to an account record stored in your Salesforce org. Access outside Salesforce services to perform a task.Now every time you create a new user within Salesforce, an autolaunched flow fires and adds the user as a collaborator with access to the payroll app service outside of Salesforce that contains their timesheet and salary. Next, you create a flow with triggers that act on the input (for example, user ID) from your payroll app. You register your external service (the payroll app), External Services converts the service into actions for use with Flow Builder. Suppose you want users to have access to an external payroll information app so that they can look up their own timesheet and pay data. Make your new Salesforce org users automatic collaborators for external, org-related applications.Before we get into the details about what External Services is and how it works, let’s take a look at a couple of examples that illustrate the workflow and highlight how External Services is changing the integration landscape for all kinds of web services.
