The REST API is a convenient alternative to the SOAP API that lets you also manage Smart Campaigns.

See also: [REST API resource documentation](https://world.optimizely.com/documentation/class-libraries/rest-apis/campaign/optimizely-campaign-rest-api-1/)

REST supports several standards and formats, such as HTTPS, URI, JSON and XML. You can retrieve data from and send data to Optimizely Campaign via REST API.

## What can I do with the REST API?

You can execute virtually any function of Optimizely Campaign from a remote system without using the web browser and logging into your client manually, for example:

- Campaign management
  - Activate and start a Smart Campaign
  - Get report data of sent mailings
  - Create and send transactional messages
- Recipient management
  - Create recipient lists and add new recipients
  - Update blocklists or create a custom blocklist
  - Add recipients to an unsubscribe list
- Bounce management
  - Check the bounce status of recipients
  - Reset the bounce counter of a recipient
