Difference between put and patch in MuleSoft43

 Difference between put and patch in MuleSoft

While both PUT and PATCH methods modify resources in MuleSoft 4, they have key differences in their scope and behavior:


  • Purpose: Replaces the entire resource with the provided data.

  • Behavior:

  • Sends the complete representation of the resource in the request body.

  • Overwrites any existing data in the resource on the server.

  • Can be used for creating new resources if they don't exist.

  • Use cases:

  • Updating the entire state of a resource.

  • Creating a new resource with all necessary data.

  • Replacing outdated or invalid data completely.


  • Purpose: Applies partial modifications to specific fields of a resource.

  • Behavior:

  • Sends only the data that needs to be updated in the request body.

  • Leaves other fields unchanged on the server.

  • Cannot be used for creating new resources.

  • Requires specifying the fields to be updated explicitly.

  • Use cases:

  • Updating specific attributes or properties of a resource.

  • Making incremental changes without affecting other parts.

  • Applying individual field updates based on user input or calculations.

Key Differences:





Entire resource

Specific fields

Data sent

Full representation

Only changes

Existing resource

Can create or overwrite

Requires existing resource

Use case

Complete updates, new resources

Partial updates, specific changes

Choosing the right method:

  • Consider whether you need to update the entire resource or only specific parts.

  • If creating a new resource is a possibility, PUT can be used.

  • If you only need to update specific fields, PATCH is more efficient and avoids sending unnecessary data.

Additional Notes:

  • Both PUT and PATCH are HTTP methods supported by MuleSoft connectors and can be used within integration flows.

  • DataWeave expressions can be used within the request body to manipulate data before sending it for updates.

  • Understanding the differences between PUT and PATCH is crucial for designing efficient and focused integration scenarios.

I hope this explanation clarifies the distinctions between PUT and PATCH in MuleSoft 4. Feel free to ask if you have any further questions or require more specific examples based on your use case!
