REST API Mapping

The REST API Mapping function type maps functions to REST API endpoints.

It is defined like this:

type: rest-api-mapping
mapping:
  path: /contacts
  method: GET
  requestMapping:
    query:
      limit: 100
      offset:
        $var: $.cursor
  responseMapping:
    records:
      $var: response.data.contacts

Format

  • path – The API endpoint path
  • method – HTTP method (GET, POST, PUT, PATCH, DELETE)
  • requestMapping – Request mapping
    • query – Query parameters mapping
    • headers – Headers mapping
    • data – Request body mapping for POST/PUT/PATCH
    • pathParameters – Values for placeholders in the path (e.g., {projectId})
  • responseMapping – Mapping to transform the API response

Variables

  • credentials – Authentication credentials from the current connection
  • parameters – Function-level and collection-level parameters combined
  • Function-specific input variables

For responseMapping:

  • response.data – API response data
  • response.headers – API response headers
  • response.statusCode – API response status code

Using in Connector Files

When used in connector files, the mapping is written in a separate file named <function-name>.rest.yml (or <function-name>.api.yml).

For example:

# "list" function of the "Contacts" data collection.
# File location: data/contacts/list.rest.yml
path: /contacts
method: GET
requestMapping:
  query:
    limit: 100
    offset:
      $var: $.cursor
responseMapping:
  records:
    $var: response.data.contacts
  cursor:
    $var: response.data.nextOffset
