Choosing REST or CLI?

The extension supports both REST and CLI (Command Line Interface) endpoints. Which one you use depends on your needs, but here's the way we usually keep them apart:

  • Use CLI when the service sending data to the extension is in the same environment. This is good for situations where you need more advanced parsing and transformation of input data.

  • Use REST when the data source is external and supports REST export. DataCater is an ETA (Extract Transform Load) service that integrates well with the Interest extension's REST API.

  • Use Webhook to utilize TYPO3's built-in reactions support to authenticate

    a REST-like request (see above).

Common Properties

Which-ever implementation you choose, there are a number of common properties that you will be using:


The name of the table you are writing records to.


The record reference. See: Remote ID mapping


A language as an RFC 1766/3066 string, e.g. nb or sv-SE. Will be set to the default language if not supplied.


(Not yet implemented. Will be ignored.)


The data you would like to write to a record. Compatible with DataHandler, but using remote IDs for references.

   "title": "What are your inteRESTed in?",
   "item_count": 100,
   "images": [
   "page": ["Page-916"]


Please note that arrays of references can only be numeric arrays!


Additional data, external to the record data, sent with a request. Can be used in conditions and transformations. See: Accessing metadata
