What purpose does the REST API OAuth Connected App serve?

The OAuth Connected App serves a vital function in enabling secure and efficient integration between external applications and Salesforce by using the REST API. This particular capability allows Lambda functions, which are serverless compute services provided by AWS, to access and interact with your Salesforce organization records in a secure manner.

By utilizing OAuth for authentication, the Connected App streamlines the process of establishing a connection while ensuring that sensitive data remains protected. This method enables Lambda functions to execute various operations on Salesforce data, such as creating, reading, updating, or deleting records, thereby facilitating smooth interoperability between cloud services.

This approach is essential for building scalable and maintainable integrations while preserving the integrity and security of user data and organizational records.
