In today’s life the Salesforce empowers the business who uses self-service-channel by providing Subscription Management API. This API will help the automation of billing, invoicing, and collecting payments for subscribed items/products and one-time sales. The Salesforce Clients who uses the Einstein AI they can use this API for calculating Risk of late payments and increase in revenue.

Developer can use this API with websites, Slack, and mobile apps. The implementation logic of this is in the form of separate API hence it decouples it from Application Layer.

The Subscription Management API includes collection of Synchronous and Asynchronous APIs.

We need to configure OAuth 2.0 authorization flow (refer the link for Connected App config steps using OAuth 2.0 Protocol)using Connected Apps to access these APIs.

In case of Asynchronous API Platform Event gets published when Process completes execution. A subscriber who is subscribed to it , listen to that event. There are many ways to listen it.

Invoke Subscription Management API- Developer can invoke it using one or more combinations of tools. Salesforce provides Flows to invoke this API. We can use invocable Actions to call this API.

When these Asynchronous system are outside of Salesforce environment. We can invoke REST APIs of Subscription Managements using tools. We can then subscribe the completion events of Asynchronous API using cometD client (refer https://cometd.org/). This client is used in various popular open source languages.

Pranshu Goyal, Director of Products at Mirekta, states: “We envision DSM to be used by every small to a medium-sized organization dealing with bad data and want to get rid of duplicates easily with no cost. We have faced issues dealing with duplicates in our organization. That inspired us to make a solution that is not only simple to use but can be used widely to make the organization’s data clean to make them more efficient and productive. We want DSM to be a solution for every organization looking for duplicate management capability better than the Salesforce out-of-the-box solution with no additional cost.”
