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.

Examples of some of the use cases which support recurring subscriptions sales are:

  1. Price Adjustments and Calculating Prices
  2. For all Service Channels with ‘Buy Now’ (checkout)
  3. Cancellation and Renewing of Subscription
  4. Payment and Billing Process

The implementation of subscription involves following Salesforce configuration

  • Connected App – OAuth 2.0 (Optional)
  • Payment Gateway
  • Product Data
  • Pricing and Invoicing Info
  • Tax Provider

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.
