In this blog post, we will dive into the various operations you can perform on Azure Cosmos DB using the Zeromagic platform. Whether you need to create, read, update, or delete data, Zeromagic provides a set of predefined actions to help you manage your database efficiently. These operations include CreateOne, CreateMany, ReadOne, ReadMany, DeleteOne, DeleteMany, UpdateOne, UpdateMany, and Custom Filter queries. Let’s explore each operation in detail to understand how you can use them to manage your Cosmos DB effectively.

Login to Zeromagic Platform and go to you Project Console. Now navigate to Modules in the sidebar of the console. Click on the necessary Module and navigate to the Flow Builder Page.

​
1. CreateOne

The CreateOne operation allows you to insert a single document into your Cosmos DB container. This is useful when you need to add individual records to your database.
  1. Add a CreateOne block to your workflow. Set the record to add field to {{$request.body}} so as to specify the data that will be used to create the new record.
  2. In the Http Response block , set the Response Variable field to expression as {{$block-name.val}}.
